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

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, SP...

There is some  STM32H573I-DK Discovery kit from STMicroelectronics that support MB1400 on STMOD - looks like it is easirer to program there. ANother variant is STMWINKT1 or STWIN.box . All they have much more memory to reprogram. OR you may simply require STM to send you module reprogrammed to 2.4 because technically its their fault. Kit with 64KB flash memory is nonsense
