Thank You so much for the training. I have a small request please Be authentic. Let your knowledge and voice shine through instead of the music in the background.

Why does TH-cam only have 7 parts? Your website has way too many advertisements. It isn't easy to read it. My Laptop fan starts as soon as I visit your website.

Please turn the music off and only highlight differences if they exist with other platforms instead of repeating the steps on them.

Please provide Github link where code is located.

How is class used? All platforms are running Linux so why repeat on each?

Please remove the music. It is not required. And I don't see any difference between Ubuntu and raspberry so why repeat everything?

thank you best tutorial

I am using stm32 h7 i am able to move my code from bootmode(bt0 high ) to application mode But when I want to read and write data from USart1 it shows some random data which gets filled in my array And my usart is also not working.

Hi sir can you do a video on SPI protocol esp32 c6 board with serial flash W25Q128JV. I have been doing it from last 3 weeks but I am unable to do it properly. My humble request. Please . Thankyou.

I have followed every step that you said in video but application. bin file and bootloader. bin were not generated in my build.my controller was STM32H723ZGT6. please help me.

great tutorial but as i understand "read" operation will give you data from the whole bar and if i want to read the particular byte is it possible to read from particular addr in a bar, like read(base_addr+offset, len)?

thanks alot

Hehe.. This series helped me in 2 aspects. 1. Able to gain knowledge on Bootloaders (SW and HW ). 2. Learnt how to use datasheets for SW development. Thank you so much.

thanks you so much

Hello, I'm trying to do this, but I always get error in the received end of frame. The end of frame always came 0xbf. If I comment out that part to ignore, the CRC came wrong. Calculated CRC is 0x4e08bfb4 and the crc that came is 0xb4000000. If I upload the previous version and previous PC-Tool everything works perfect. Could the new PC-Tool have problem? I checked the with the online CRC tools and when I make CRC-32 calculation of 0x00 I got the same result as the STM32 calculation Edit: I found the problem. Here is data that PC Tool generating. There is so much zero. DATA_BUF[3...7] are unnecessary CMD:0 CRC:4E08BFB4 DATA_BUF[0]:aa DATA_BUF[1]:0 DATA_BUF[2]:1 DATA_BUF[3]:0 DATA_BUF[4]:0 DATA_BUF[5]:0 DATA_BUF[6]:0 DATA_BUF[7]:0 DATA_BUF[8]:b4 DATA_BUF[9]:bf DATA_BUF[10]:8 DATA_BUF[11]:4e DATA_BUF[12]:bb

yo this video is super W good stuff

Opening COM5... unable to open comport Can not open comport OTA ERROR unable to open COM port

Since http GET with URL parameter is not good practice for activating LEDs (192.168.1.25/LEDControl.cgi?green=OFF&blue=OFF&red=OFF), is it possible to process a POST http request with a real payload doing the same ?

can u explain more detail about why you command promot there and how to use it and what is pctool

why you are not providing complete classes

thanks a lot G

You updated the user fw app via the bootloader. But when you did this, you are using the built-in ST-LINK in the board???

You told that use SD card for update firmware but use UART ???? . This is code from Github : printf("Starting Firmware Download!!! "); /* OTA Request. Receive the data from the UART4 and flash */ if( etx_ota_download_and_flash() != ETX_OTA_EX_OK ) and after this : //receive SOF byte (1byte) ret = HAL_UART_Receive( &huart2, &buf[index], 1, HAL_MAX_DELAY ); What goingg on ?

***FYI everyone ST-LINK Utility has been replaced with "STM32Cube Programmer"***

Very underrated

the "Enable the ethernet via USB0" part save my life :)) thank you so much!

didnt work, my cubible using sepam relay and same port config but doesnt work

It is necessary to clean Flash memory before writing new application version or this step could be omitted?

In tera term no com port is showing for ST link. So I cheacked in device manager about this it showing my STM port under "universal serial bus devices." Sir, how you connected it to COM port ?

Very Good Series. Keep it up. Thank you.👍

how the code is change if I have esp32 for Bluetooth?

Thank you, this still works into mid 2024!

It is very useful 😃 not boring one

Thank you

The web version of this tutorial requires disabling AdBlock. A good sign to stay away from such sites. Goodbye.

Hello. I am confused since in all the literature I have read up until this point I have been told that Cortex-M MCUs have a full-descending stack model and what it is loaded into the MSP after reset/power is the direction of the top of the stack i.e 0x200X X000.The value that you say gets loaded in the MSP (0x20000000) is actually the direction of the begining of the SRAM memmory that leaves virtually no room for stack to grow. MSP should point to the end of SRAM (direction depends on the specific MCU but it is in the range of 0x200X X000) to allow it to grow downwards.

your accent is soo bad cant understand properly

Where can I download the driver? Do you have a download link?

Hello friend, plz make a video on Bluetooth firmware update over the air using STM32F103C8T6.

an incorrect ip address shows up on the terminal when I perform ipconfig : I get 169.254.83.55 instead of 192.168.1.25 that I have set up. The ping doesn't wor out. What could be wrong?

How can i fix error "undefined reference to `httpd_init'"?

unfortunately very bad quality, nothing to understand

Please remove the background music.. its too disturbing... not able to foucs on content

slot 0 slot 1是将内容拷贝到APP吗？

why dont you interface a 32 gb sdhc card, I think nobody was able to achieve that since time immemorial...

I love you EmbeTronix

Your pronounciation is horrible, try at least speak slower - maybe it improve a bit.

Hi sir, Thanks for you tutorial But it's seem have problem with transmit data from hostap to STM This issue like: OTA START : NACK OTA START [ex = -1] send_ota_start Err OTA ERROR I have doing some debug with your code, this issue happen because in your etx_receive_chunk on STM function will recive each part in turn, but function on hostapp will send all data in 1 turn without wating each part of etx_receive_chunk return, so the second part of fucntion etx_receive_chunk dont have data --> timeout --> send NACK. Ex: In funciton sent_ota_start on hostapp will send all data in step receive SOF byte of etx_receive_chunk and wait respone. I try to increat delay but I dont think it is a good idea. I very happy if you fix this issue. Many thanks!!!

For nucleo F303RE what are the flash memory addresses? Its not working for this board, though compilation and flashing proceeds OK, seems.
