Procedure to update MB1400 Wi-Fi module firmware with STM32H7S78-DK

[Fef]

Hello,

I am using the STM32H7S78-DK Discovery kit, which includes the MB1400 Wi-Fi module (as described in the UM3289 documentation).

I am developing with Keil µVision 5, and I would like to update the firmware of the MB1400 Wi-Fi module, but I cannot find any detailed procedure for doing this using the STM32H7S78-DK board.

Could you please clarify:

1. Where can I download the latest MB1400 (EMW3080B) firmware compatible with the STM32H7S78-DK?

2. What is the exact update procedure (UART or SPI interface, boot mode pin settings, required tools, etc.)?

3. Is there any example project or script showing how to perform the firmware update directly from the STM32H7S78-DK (similar to the approach used in AN5534 for other boards)?

Thank you very much for your support and guidance.

Best regards

Have you tried the X-WIFI-EMW3080B ?

Yes, I have downloaded the x-wifi-emw3080b.zip package.
Inside, I found the SPI firmware binaries and update instructions for other boards, such as:

EMW3080update_B-U585I-IOT02A-RevC_V2.3.4_SPI.bin
EMW3080update_STM32H573I-DK-RevA-MB1400-SPI_V2.3.4.bin

However, there is no firmware file or update guide for the STM32H7S78-DK Discovery kit, even though this kit is sold with the MB1400 Wi-Fi module.

I have tried the procedure for the STM32H573I-DK, but it cannot work because the STM32H7S78 (STM32H7SL8H6H) only has 64 KB of Flash, so the same method is not applicable.

Also, the UM3289 documentation mentions to refer to the X-WIFI-EMW3080B product web page for the latest firmware and update procedure, but there is no specific guide or driver available for the STM32H7S78-DK.

Could you please confirm whether an official update procedure or firmware file exists for this board?

Thank you for your help.

You can try to ping support so they can explain how to do this via 3080 console.<<  fota | firmware update by http/https, fota <url> <md5>
>>
Its a good challenge to check their skills - they have full documentation - not just soldering iron, USB to USART and Salea analyzer ---| fota | firmware update by http/https, fota <url> <md5>. I understand that 64k ram is not enough so probably other board is needed to go in classic way. U585 has no spi2 anywhere so i guess reflash via fota is easiest way

I spent a lot making 3080 go live on U585 on SPI2. I guess update is done by loading STM program with V2.3.4 software inside. I also was able to access console and probably it is possible to update right from there - I saw the commands in console. If someone is interested they can me free board and wifi and i will share all possible ways doing this job. I was working with STM support and found them pretty useless. Also I ordered couple original 3080 from Aliexpress for experiments.

I spent 3 weeks recently of tearing down MX EMW3080  If somebody will sponsor for STM32H573I-DK board with MB1400 I will find how to update it with having minimum 64KB flash memory like Fef has. Also I am thrilled to compile  X-CUBE-AZURE-H5 - Microsoft Azure IoT software expansion for STM32Cube targeting STM32H573I-DK - STMicroelectronics. I ordered two chips from China and put on breadboard. Nevertheless i saw that the way how STM U585I-IOT2A  work with and it is much more tricky. This is related to clocking, USART, SPI2 configs and all sequence of calls to board. My first two versions based on MX CUbe generated code did not work at all and USBx version did not work and only accurate extract from HTTP Web example in bare metal variant worked. honestly i have serious doubt that Azure with UsbX and ThreadX will work on H573. If somebody ready to share experience of efforts with me just email me. I plan to explore Nordic nRF7002 in a week . Murata/NXP and RTL7020DN are also in queue
