u-Link NAND program Openwrt on Meraki MR33.

- The 3.3v to NAND only draw 90mA. So the power is directly from the u-Link NAND.
Program the openWRT on MR33 only need to replace the u-boot (2012 version) and ubi. The process is easy and fast.(about 10 min)
Thanks, for video, For now i know what hardware need to do OpenWRT on MR33 with new uboot!
Love your videos! Thanks for taking the time to record everything. It's been incredibly helpful.
Glad I can help. Others in the community had done great job.
Will this process work on a MR34 AP?
Same firmware will work?
If not, do you have the firmware available that would?
MR34 isn't supported yet.
Which UART do you use?
@@oliverstammer637 cheap ch341 board.
thank you for uploading this.
what's the usb ur using? how can i make one?
IT is a u-Link NAND cost about $62 online plus ship. Just search for it.
The wallmount backplate is just a spring-mechanism. Just press is with your fingers. There's no needs to use a screwdriver ☺️
Agree,I latter on find it has a spring-like clip and easy to remove.
Thank you for sharing! Will this method work for MR42?
Have not tried MR42, Depends on if it is easy to clip the NAND flash.
Where do I get that cable you are using?
The clip is bought from aliexpress.
@@usbbdm Do you have links to the used hardware?
@@TechTonor Clip can be found on aliexpress. Programmer on www.usbjtag.com
I found time to watch the video. It's great! I have a few questions for you.
- Are you holding the Power to the UART Connection, while flashing the chip? IT was still connected to the pins, so I need to ask.
- You are flashing the chip without desoldering. Most people recommend to desolder it. Is there no risk of doing it, without desoldering?
Thanks for a great video 😀
And oh, maybe add information about the programmer in the details too, including which hardware you've used. That would be helpfull, too.
No. When programming the UART is not powered on. Power is from u-Link NAND. It only draws 90mA 3.3v.
@@TechTonor I have created several video about u-Link Nand already. Let me know if you still have questions so I can make new videos to clear things out.
Hi, where to buy the clip to flash the nand using u-link nand ? thanks
I got it from Aliexpress.
@@usbbdm can you please put down the links to the parts? Thanks
@@miguelfna Search for 360-Clip Tsop Nand and find the one you like.
@@joppewillems I do not think so. This is for easy shipment.
@@usbbdm but which one 32pin/48/56 ?
@0:15 all you have to do is press the button in to take the mounting bracket off. No prying needed.
Agree, I latter found that is quite easy to take off.
is there an alternative way to do this
Remove the flash and program it using a NAND programmer.
@@usbbdm oh but I mean like just using the serial interface I won't be able to downgrade or is NAD Programming the only option I have and also can you recommend some and programmers.
@@rayyanrahman262 For some newer u-boot, the serial port method does not work.
Would you be willing to offer this as a service to flash AP's? I would like 2 x MR33's doing.
Thank you
You mean physically send me the AP to flash? I do not know if it is worth doing that due to the shipping is quite expensive.
@@usbbdm where are you based as I'm in UK?
I'm a tech and probably capable of doing it, as flashed other types of products in the past, and also can solder with thr correct ESD and SMC rework etc, but I've never done this before so was wanting an idiots step by step guide and also links to everything i would need if possible otherwise :) great work and krep it up :)
@@moodyk1979 I am in North America. Converting MR33 is for fun. Having someone doing for you lots the fun part.
@@usbbdm believe me i want to try it but i want to use them asap, as I want to install them into my new appartment. Would you be able to email me so we could talk about helping me doing this from scratch like and idiots guide? Thank you
@@moodyk1979 Come to www.usbjtag.com and we can chat there.
C'mon... not anyone are programmers! Explain how you do it! Show step by step and also a easy way... for me (I'm not a programmer) it is like... yeah another one who say nothing! So... step 1, 2, 3 .... and finish!
Thanks. I will make another video soon. This time I will explain less. But provide a script.
Unless you are doing a lot of these then JTAG is a waste of money and time. Anything more than UART console and a TFTP server and you're wasting your time really
If you have the right u-boot you can do it via UART. The problem is the new u-boot blocks the UART.
@@usbbdm And given the way Merakis update it's extremely likely it has the new u-boot
Maybe a video into the realities and charges of JTAG would be good. Talking about JTAG without mentioning the costs and complexities may cause people more problems than it solves
