stm32wb55 nucleo & dongle DFU

[Marek Pio]

Hello,

I have STM32WB set from workshops that I borrowed from my work.

The problem is both pcbs are not recognised in DFU mode. I connected stm32f4-discovery and it's recognised correctly.

I'm Linux Mint 19 user and I have followed CubeProgrammer's installation manual. I did the same on Windows 10 with the same effect.

On nucleo board I connected pins 5-7 and USB MCU SOURCE.

On dongle board I set switch position to BOOT.

What is the problem? It's look like both of pcbs don't have bootloaders.

Do I need to buy a new stm32wb development kit or can I program a new bootloader file?

Can I flash the Wireless Coprocessor Binary without DFU? I want to turn on BLE examples, but they didn't work.

A new devboard works without any problems.

Hi,

have you found a way, how to update Co processor without USB? Is it possible to access it from SWD/JTAG?

Thanks!

same issue here, boths seem dead. Boards are the preview ones I got in one of ST workshops

Hi! I got same issue today. After removing old coprocessor FW i was not able to detect board by USB in DFU mode. I have custom board. Port LPUART was connected via USB-serial to the PC.

I have removed FW without any issues:

But after that - i was receiving message - USB device not detected.

I made next steps and board was able to be detected via USB:

1 - Erased FLASH in normal mode;

2 - Erased FLASH, sector by sector after booting in DFU mode (with boot0 signal)

3 - Disconnect USB-Serial port, connected to the PC.

Now board works OK! Hope this post helps you.
