Error: FUS_STATE_IMG_NOT_FOUND

[wim_board]

Hi,

Totally newb. I have a custom board with a STM32WB55CEU6. Connected over ST-LINK.

I'm trying to upgrade FUS. Using stm32wb5x_FUS_fw.bin at 0x0807A000

Everything seems to work fine until the very last step, where I get an error: FUS_STATE_IMG_NOT_FOUND: Firmware/FUS upgrade requested but no image found. (such as image header corrupted or flash memory corrupted)

Any ideas?

Here's my log:

Hello,

Please check video guidance how to update FUS or stack. Up to date version of STM32CubeProgrammer is able to made even more steps for you. Please ensure, that no memory protection is active. When you're still facing issue, mass erase of the memory will help - there may be some data, which are by change wrongly identified as FUS header, so update is not done with correct data.
On custom board is also important to ensure voltage is stable during flash write and erase operations (proper decoupling and stable power input).
Is it working for you now after mass erase prior to FUS update?

Thank you in advance for your feedback,
Lubos

Hello, and thank you!

I am basically already following the tutorial. I use a STLINK-V3SET so some steps are different.

I did a mass erase. No difference. Same error, same logs.

The board may, off course be faulty. I didn't build it myself and I don't have the tools to check everything. But things seems to be working all right. I can read whats on the STM32, I can make changes to it, I just can't get the FUS update to work.

Anything else I should try?

I'm sorry for late reply.
Please check also option bytes to ensure there is no memory protection active.

For verification, could you please post content of your security option bytes?
What is the content of FUS information window on your side?

For verification, could you try FUS update also on some different custom board and also on some STM32WB55 nucleo board?
