I love how this turned from "hello world on a cheap new embedded chip" to "summarize and compare 40+ years of instruction set architectures" while still being comprehensible!
It's a nice, well done video. I did notice one problem though: Andrew may have confused Arm and MIPS because he said Arm is like RISC-V in not using flags/condition codes. While ARMv7 (Thumb2) added "cbz"/"cbnz" instructions that branch based on the contents of a register, Arm in fact has NZVC condition codes in the DEC/Motorola tradition (PDP-11, VAX, 6800, 68000, 6502 etc) and all other conditional branches are based on those. The Milk-V Duo is a nice little board and the 1 GHz CPU pretty capable, but the 64 MB RAM is a little limiting. It's enough to run emacs and gcc on the Duo itself to write and compile small to medium programs, which is cool. Meanwhile Milk-V has announced the Duo 256M which increases the RAM to 256 MB, and (weirdly) adds a 1 GHz Arm A53 core to the 1 GHz and 700 MHz RISC-V cores in the original Duo. Price and shipping date haven't been announced yet.
linux is kinda overkill depending on what you are actually planning to use it for. for a lot of embedded stuff an RTOS may be more suitable, but since linux is easy to find stuff for its kinda nice to just have a full OS for. and yes. the unix/*nix/linux way of making basically everything a file is super cool
It's certainly a useful and valuable design paradigm, even if it isn't perfect in every situation. Too much complexity at the bottom of the software stack can really make a mess. --- That said, you can "have a whole OS" without necessarily including the Linux kernel and GNU tools. CP/M and MS-DOS, among hundreds of other historical example, were all /operating systems/ in their own right, even though many had little or no built-in support for any kind of local networking of machines.
Isn't Linux a "everything is a file" OS? The webcam? A file. The screen? A file. Your keyboard? A file. A file? A file. Nothing? You guessed it, a file.
@@top.of.reddit For the most part. Since Linux is "Unix-like" and not a real UNIX system it doesn't always follow that design pattern, though. For most hackers and makers it's useful, though! I'm about to start working on a script to control a USB-connected CPU fan using the USB device files, for example.
@@merthyr1831 : A lot of the certified Unix distributions didn't make everything a file either, it wasn't actually rare. At any rate, the "real" "everything is a file" OS is Plan 9 and it's derivatives, which a bunch of the original Unix guys created as a successor to Unix- in essence, enough of a mess had developed in the Unix space that they had enough reference points to figure out how to make an OS be more Unix than Unix itself. Anything with FUSE support can be turned into a Plan 9-alike, so much of the *nix world will probably eventually drift over in that direction.
I like RISC-V. It seems highly comprehensible. This board and the work they put in to making it accessible and usable seems exceptional. I'll pick up a couple. And your discussion of it and of ISA's really enhances and completes the package! Thank you!
Man, it's so refreshing to hear about a device from somebody that knows what they're talking about (mips, arm, ppc experience). Does this little chip have any audio capabilities?
It doesn't show up in the peripheral docs, but it looks like it does potentially support using the ADC input for audio. I'm not sure really. My guess is yes, since it's a security camera chip, but software support might not be all there.
@@apalrdsadventures According to the docs there is an audio subsystem with I2S and PCM capabilities. Also, regarding the RISC-V branching instructions, I am not sure what you mean by doing a subtraction first. RISC-V doesn't need an extra subtraction, it happens internally with the branch instructions, which admittedly is a small difference. By the way, BEQZ is not a real instruction, it gets expanded to BEQ x0 by the assembler. The compiler here hides some things.
As an old "full stack dev" (including assembler on some archs) - it was a joy to listen to your presentation. The right level and speed for a more tech savvy audience. Thanks 🙂
Fabulous hands-on with affordable hardware I didn't know exist! Very nice explanation at the end about different architectures! (BTW Big thanx for doing some magic on the audio side of things! Excellent listening experience with this video!)
ARM has sorta pay for what you need with the Cortex M/A/R families, but you still have to buy the core from ARM, with no options for alternate designs or designing the core yourself, and there aren't very many options.
This is one of the best videos I've seen in the past few months, at least. Super well explained, useful interjections and lots of info about the different asm variants. Plus the board itself looks super interesting, I just wish there was a European reseller or something. Or that it wasn't sold out... Again, excellent video, keep up the good work!
@@therealchaydThey do, but it turns a 10€ computer into a 30€ computer. Plus the possibility of huge import taxes. At that point you might as well get a more capable device. It's only worth it if you're buying in quantity.
I'd love to see more like this. I've recently finished work as full time developer, I never got to do low level stuff but I was always interested. Here's an idea, maybe you could put together a short series of videos, say half a dozen, introducing people to RISC-V and low level development. We could pick up a board like this for cheap it to follow along. Obviously, this is a huge amount of work you'd have at least one person that was really interested :)
I have a video coming up using this to build a display, so I'm sure there will be plenty of embedded programming in that video. The nice thing about using Linux on this board is the development setup is way easier than using a microcontroller.
@@apalrdsadventures Subscribed, and waiting for that video. I was thinking of using this board to drive a SSD1322 Oled at +60fps to replace some unobtainium VFDs.
Didn't expect to dive into systems architecture like this when I opened TH-cam for dinner, but thanks! The sysadmin stuff is what I do myself, this is a topic I'm not familiar with (other than hearing about it) so this video was really interesting and so well explained/delivered I feel like I actually understood!
I come from the computer science world, so while I did some assembly (in MIPS) in college it wasn't a major part of my education. Also did only a little with hardware. If I could do it all again I think I might have chosen computer engineering. I tinker around with dev boards and I love the hardware side of things. While the pure theory stuff with algorithms scratches an intellectual itch, the fact is we live in the physical realm and doing stuff with microcontrollers and small boards and all the various I/O they offer makes for some fun and very practical projects. Honestly, college was wasted on me. I had all this opportunity to take classes in network security, robotics, computer engineering, etc. but never took advantage when I was there. I just wanted to get my degree and get out into the real world. I should have taken so many more electives in related fields. So now I just learn this stuff on my own with the internet as a resource. I'm also really into radio stuff, got my ham license.
Wow! I'm seriously impressed by your knowledge and, of course, this video. I was as involved with assembly language 50 years ago as you are now. I cut my teeth on the IBM 7074 and the CDC 6000 series. I also dabbled in Z80, 8080, 6800 and 6502. I wrote a rudimentary OS for the 6502 using a Tarbell floppy controller and a couple of 8" floppy drives all in assembly language. So this video took me back. Thanks!
CDC 6000!!! Wow! Arguably the first RISC ISA (Cray 1 was the 2nd), though the term hadn't been invented yet. With 15 bit and 30 bit instruction lengths it was really quite similar to RISC-V or Thumb-2. The only really weird (but valid) thing was there were no load or store instructions. Instead you just stored the desired memory address into one of the A registers and the corresponding X register was automatically loaded (A1-A5) or stored (A6-A7) from memory. I fall between you and Andrew. I started with 6502 and z80 (and TI and HP programmable calculators before them), went to university and used PDP-11 and VAX, and by the time I graduated the first 68000 Mac was out. I worked on a DG MV10000 supermini (VAX competitor) for a couple of years, but from 1987 on was exclusively Mac, then Linux in the late 90s when MacOS 9 was looking very dated, then back to OSX in combination with Linux. Later I got into compilers and ISA design (proprietary and RISC-V).
Excellent video. I like your straightforward approach of showing the board...showing the compiled code. Good explanation of instructions and history. I have been working with low level code for 12 years now and did not know about the 16-bit ones 😂😂
Really enjoyed your presentation and video. I especially liked your c and asm walkthrough. I think you would make a GREAT teacher as well. Looking for more content like this.
You're bad ass dude! Thank you for sharing! I plan on teaching myself assembly on RiscV before moving on to high-level languages and was impressed with how many ISA's you were familiar with. I was like, "Damn.....I'ma suck!" 😛
small correction: morse code is not a Huffman code, since it doesn't satisfy the prefix-property (meaning that no encoded letter is included at the beginning of another letter), which is the main point of doing Huffman encoding anyway. the benefit of these prefix codes is, that do not have to incorporate separations for letters, since you know exactly when a new symbol starts. there also exist "morse" codes which are prefix codes, but those are not as commonly used/known as the standard version. small example for the point above: take the morse sequence .-. this can be anything from these words: AE, EN, ETE or R with a prefix code (such as a Huffman code), there would only be one possible translation, even when omitting separation

So technically we could run statically compiled Go tools on it? Not sure if goc supports RISC-V, but since GCC does, GCCGO should work I guess. Edit: Just looked it up, there's actually a goc port for RISC-V. Nice!

Hello! OI just found your channel! I am so happy I did, you do so many things I want to do or am doing. Use Linux a lot but you do so much more than me. Programming in SDL2 on linux mostly but I have other things too. Looking forward to catching up on all your videos.
Thanks for the video. I like RISC-V because I'm not locked in a ARM hold. Went to mentioned links but seems sold out. Will try back on occasion. Liked and subscribed!
There's also a Milk-V Duo S now and it's fire 🔥 It also has a RISC-V cpu, but also a second CPU with ARM, not 64 MB, but 512 MB of RAM, it has Ethernet and USB ports on the board itself (you don't need to buy another board for it!), but who needs Ethernet, when this board also supports WiFi and Bluetooth (make sure to buy model with it!), it says it also supports audio via GPIO header and it also has more GPIO pins. I bought Milk-V Duo S (with WiFi) myself, and it's good. It was long to wait for Arduino support in software, but we finally got it! 🎉
I thought that the Duo was doomed to obscurity, but it's been amazing to see it get more popularity and support. Fairly recently I setup X11 forwarding (something it shouldn't do) and used MPV to rickroll Milk-V forum members lol
@@apalrdsadventuresyes, for some reason Milk-V includes a whopping 256mb swap partition with the default image, but you need to manually mkswap and swapon it yourself
I love all these dev boards but for embedded systems it would be hard to beat the older chips like Z80 or 6502 (and derivatives) with mature development tools. These chips will be great for edge computing and custom processing. Love the innovation here.
Been messing with MIPS64, not with SGI hardware (tho I've got an Octane2, O2 and others) but with an Exablox RAID appliance that I picked up on eBay and discovered it's a Cavium Octeon 6-core machine running on a barebones Busybox Debian, 16GB of RAM. Octeon hardware is pretty interesting as there's hardware packet processing, hardware REGEX for packet inspection and gzip compression in hardware.
Pretty cool. I heard of this board few weeks ago, and definitively going to grab few to do some testing and development. If you want to extend storage, you can use micro SD card, USB drive, or just mount some file system over network (i.e. NFS or sshfs). This way you could even get rid of cross-compiling and compile directly on board. Crazy.
Yes, 64 MB is just enough RAM to run a full current version Debian/Ubuntu/Fedora server install with about half the RAM free, making it possible to run emacs, gcc and so forth to edit and build small to medium programs. There has recently been a 256 MB version of this board announced, though we don't yet know the price or delivery date. My first Linux machine in the mid 90s (a Pentium Pro 200) had only 32 MB RAM!! Well, that really wasn't enough for serious work and I soon threw another 128 MB in the free sockets, which was ample at the time.
@@BruceHoult I see in their Git repo mention of a new model with 256MB of RAM, plus an extra core (ARM one, as an addition to existing to RISC-V cores; a bit weird, but ok).
I've done assembly programming on the following systems: DEC PDP-8, DEC PDP-11, Intel 8080/85 (& Zilog Z80), Motorola 680X0, IBM 360/370. At Bankers Trust of SC, I had to add the check number to a tape that was read by a microfiche writer. The PL/1 was impossible to understand with way too many GOTO's. I rewrote that in 370 assembly. The mainframe operators said that the program nearly spun the tape off the tape drive.
we need clx for prosumers and also gpu #eat the document this was an informative look as you included all the arcane and dirty work - setting it up and looking at what is included - riscV will be a force in a few years and challenge arm and x86 - more room for innovation
The shipping price scared me off for now but I want to test drive RISC-V and will keep an eye out for another group-buy. I appreciate your great taste in keyboards and t-shirts
Ah, backwards compatibility with the 70s. Where would we be without it??? Well, in the 60s I guess, since everything since then has had it. Hooray for consistency.
Auto sub cause who would not love a nerdy good stuff like this.

Raspberry Pi was also supposed to be a cheap alternative for hobbyists. Now it's more expensive than some Intel SBCs. Only time will show where it's all going.
Interesting little package for sure! Another source of PPC motherboards/systems which are much cheaper than the Talos II would be the next gen PPC Amiga hardware using a variety of CPUs from PA Semi, Freescale, AMCC, and others, from single to quad core. The Talos II offers more computing power per dollar, but for general purpose RISC computing the PPC Amigas are relatively affordable.
Relative to what? The so called "Amiga" boards are small scale production, poorly supported, low end tech, and will likely disappear in no time. They have little in common with the latest POWER ISA. You would probably be no worse off buying an old PPC Mac and learning on that.
7:20 Here I thought that all of the modern boards without visible transformers were not standards compliant! I had no idea that they were hidden in the RJ45 port now. 24:20 I have a Lemote Yeelong with a MIPS-el (Little endian) processor. It is supposed to have x86 compatibility instructions to speed up emulation: but never got around to playing with it.
Better for machine control, because it doesn't have to do calculations, more or less dealing with libraries and no floating point needed.. that can be off loaded to the 'master'. Speed can matter and 2 core, if programed right gives a back-up redundancy in critical implementation.. a worker and a guard that can pickup the worker's implementation and flag operation, but still get communication and operational results if a core freezes. Code smart and know your core kernel functions. I wish that they would do some of the micro controllers in dual core and 16 bit..
I love how this turned from "hello world on a cheap new embedded chip" to "summarize and compare 40+ years of instruction set architectures" while still being comprehensible!

The major benefits of RISC are that it follows the KISS rule rather well, and is also modular IIRC.
With optional modules it's performant up to big systems, and without it's scalable down to small systems.

small example for the point above:
take the morse sequence .-.
this can be anything from these words: AE, EN, ETE or R
with a prefix code (such as a Huffman code), there would only be one possible translation, even when omitting separation

Yes, with Morse code you have to listen for the rhythm, if you listen to it as dots and dashes, chances are you'll just hear gibberish.

Looking forward to watching your older and new video’s! All the best from 🇳🇱
Very informative… camera looked better than most mid-rang leaning towards high end commercial security cameras! Good job…
It's $3.50 for the camera module, but I agree it does look pretty good for the price.
Very nice little board. I can think of tons of things to do with this. Thank you for the in-depth and detailed video!
As an average Joe, what are some practical uses for this board?
Hello! OI just found your channel! I am so happy I did, you do so many things I want to do or am doing. Use Linux a lot but you do so much more than me. Programming in SDL2 on linux mostly but I have other things too. Looking forward to catching up on all your videos.
Thanks!
Glad you liked it!
Thanks for the video. I like RISC-V because I'm not locked in a ARM hold. Went to mentioned links but seems sold out. Will try back on occasion. Liked and subscribed!
Very interesting, especially the assembly, i remember arm Assembler from a long while ago.
Wow!!!! I gotta buy one of these. Love your videos man keep it up
Nicely done. Very well explained and interesting even though most of the programming stuff was over my head I still gained some insight. Subscribed😊
Glad you enjoyed it!
I recently discovered your channel, and I love it! Keep it up! 👏
Very cool video! Thanks for doing something different and more involved than the common format of: 1. Talk about the specs, 2. Run blink demo. 😂
There's also a Milk-V Duo S now and it's fire 🔥
It also has a RISC-V cpu, but also a second CPU with ARM, not 64 MB, but 512 MB of RAM, it has Ethernet and USB ports on the board itself (you don't need to buy another board for it!), but who needs Ethernet, when this board also supports WiFi and Bluetooth (make sure to buy model with it!), it says it also supports audio via GPIO header and it also has more GPIO pins.
I bought Milk-V Duo S (with WiFi) myself, and it's good. It was long to wait for Arduino support in software, but we finally got it! 🎉
I have it and it's great
I still prefer wired Ethernet over wifi though
I bought that board a month ago. I haven't gotten to it yet. So far it seems awesome.
Awesome video, I'm going to grab a couple of these soon, thanks!
Good timing have 2 of these on order with breakout and camera
I thought that the Duo was doomed to obscurity, but it's been amazing to see it get more popularity and support.
Fairly recently I setup X11 forwarding (something it shouldn't do) and used MPV to rickroll Milk-V forum members lol
I'm guessing it's using quite a bit of swap doing x11 applications?
@@apalrdsadventuresyes, for some reason Milk-V includes a whopping 256mb swap partition with the default image, but you need to manually mkswap and swapon it yourself
So cool, can't wait to get my tinkering hands on one!
This is so cool! I would like to see it run some CLI applications though.
I love all these dev boards but for embedded systems it would be hard to beat the older chips like Z80 or 6502 (and derivatives) with mature development tools. These chips will be great for edge computing and custom processing. Love the innovation here.
Caraca, um dos melhores vídeos que assisti ultimamente no TH-cam!
thanks for the code, i will be studying it and using it when i get my board
I just ordered one! Amazing content!
Finally getting around to ordering some to play with!
1:14 "The instruction set is not particularly complex" Well, I think that was the whole point!
Been messing with MIPS64, not with SGI hardware (tho I've got an Octane2, O2 and others) but with an Exablox RAID appliance that I picked up on eBay and discovered it's a Cavium Octeon 6-core machine running on a barebones Busybox Debian, 16GB of RAM. Octeon hardware is pretty interesting as there's hardware packet processing, hardware REGEX for packet inspection and gzip compression in hardware.
I like your shirt for the kernel build portion :)
Definitely a lot of kernel building when you play with RISC-V
Nice use of cloest space, I'm diggin it. Good vidya thanks!
Pretty cool. I heard of this board few weeks ago, and definitively going to grab few to do some testing and development. If you want to extend storage, you can use micro SD card, USB drive, or just mount some file system over network (i.e. NFS or sshfs). This way you could even get rid of cross-compiling and compile directly on board. Crazy.
Yes, 64 MB is just enough RAM to run a full current version Debian/Ubuntu/Fedora server install with about half the RAM free, making it possible to run emacs, gcc and so forth to edit and build small to medium programs. There has recently been a 256 MB version of this board announced, though we don't yet know the price or delivery date. My first Linux machine in the mid 90s (a Pentium Pro 200) had only 32 MB RAM!! Well, that really wasn't enough for serious work and I soon threw another 128 MB in the free sockets, which was ample at the time.
@@BruceHoult I see in their Git repo mention of a new model with 256MB of RAM, plus an extra core (ARM one, as an addition to existing to RISC-V cores; a bit weird, but ok).
@@movax20h yes, I mentioned that new board in the comment you replied to.
@@BruceHoult You are right! Thanks.
I've done assembly programming on the following systems: DEC PDP-8, DEC PDP-11, Intel 8080/85 (& Zilog Z80), Motorola 680X0, IBM 360/370.
At Bankers Trust of SC, I had to add the check number to a tape that was read by a microfiche writer. The PL/1 was impossible to understand with way too many GOTO's. I rewrote that in 370 assembly. The mainframe operators said that the program nearly spun the tape off the tape drive.
Cool little chip, I think I will use it in future projects!
I didn't knew the riscv until I found it mentioned on a recent comment on a Jhon Carmack post about OSS
Great stuff, thank you! Keep fighting the ipv6 fight
They actually merged my kconfig changes and included them in the future releases, so no more need for my builds to get v6 support!
we need clx for prosumers and also gpu #eat the document this was an informative look as you included all the arcane and dirty work - setting it up and looking at what is included - riscV will be a force in a few years and challenge arm and x86 - more room for innovation
The shipping price scared me off for now but I want to test drive RISC-V and will keep an eye out for another group-buy. I appreciate your great taste in keyboards and t-shirts
My Duo cost $14.62 USD including shipping from China across the Pacific to New Zealand.
I don't know most of the terms, but I really liked the video!
Ah, backwards compatibility with the 70s. Where would we be without it??? Well, in the 60s I guess, since everything since then has had it. Hooray for consistency.
No idea what’s going on here or what’s being said but it’s comforting to know there are smart people in the world to figure all these out 😂
Thank you. Cheers from OZ
and I enjoy your videos from which I am learning and thank you for that ;)
Woah, Louder with Crawder is doing tech videos now!!!
👍Fascinating... but I'm banging my head on the Proxmox VDI videos 🤣
Very well explained, thank you!
I did not understand most of this video but I still enjoyed it thank you 😂
I should get looking into this some more, would make like a nice cheap DIY reverse camera for my car.
Auto sub cause who would not love a nerdy good stuff like this.
Raspberry Pi was also supposed to be a cheap alternative for hobbyists. Now it's more expensive than some Intel SBCs. Only time will show where it's all going.
Interesting little package for sure!
Another source of PPC motherboards/systems which are much cheaper than the Talos II would be the next gen PPC Amiga hardware using a variety of CPUs from PA Semi, Freescale, AMCC, and others, from single to quad core. The Talos II offers more computing power per dollar, but for general purpose RISC computing the PPC Amigas are relatively affordable.
Relative to what? The so called "Amiga" boards are small scale production, poorly supported, low end tech, and will likely disappear in no time. They have little in common with the latest POWER ISA. You would probably be no worse off buying an old PPC Mac and learning on that.
Thx for the introduction! Great video!
Subbed. Awesome explanation and walkthrough.
Have you ever considered partnerships? You do great work!
It'll be cool to see RTOSes and SeL4 on these types of computers.
Great overview, thanks!
awesome video man dont stop
FYI they are out of stock as per 10 october 23 ($5) but AliX has them for $10 incl postage
they went out of stock a few hours after the video published, oops
AliX has them for $10 incl postage so it is not that bad
very compelling video. I might need to get me one of these system on a chip doohickeys
Voice volume is good now. Thanks.
This looks like the most awsome device!
7:20 Here I thought that all of the modern boards without visible transformers were not standards compliant!
I had no idea that they were hidden in the RJ45 port now.
24:20 I have a Lemote Yeelong with a MIPS-el (Little endian) processor. It is supposed to have x86 compatibility instructions to speed up emulation: but never got around to playing with it.
Better for machine control, because it doesn't have to do calculations, more or less dealing with libraries and no floating point needed.. that can be off loaded to the 'master'. Speed can matter and 2 core, if programed right gives a back-up redundancy in critical implementation.. a worker and a guard that can pickup the worker's implementation and flag operation, but still get communication and operational results if a core freezes. Code smart and know your core kernel functions. I wish that they would do some of the micro controllers in dual core and 16 bit..
subscribed thanks to laymans explanation of arm vs x86
The problem with an OS on any SBC other than a Raspberry Pi or a board with an X86 chip, is that good software support is hard to come by.
very well made video my friend. keep it up!
That was a fast sold out group buy.
