Question

Is it possible to brick FUS 1.2?

I had my NUCLEO-WB15CC running stack full v1.15 and today I decided to upgrade it to v1.16 and got "Warning: FUS_STATE_ERR_UNKNOWN". And now I have no stack and I'm unable to install it.

And I can't even start FUS, when I try, I get those errors:

Error: FUS_STATE_ERR_UNKNOWN: Unknown error

Start FUS failed !

Error: Start FUS Operation Failure! Please, try again

My problem is very similar to this, but I have latest FUS. IPCCDBA is 0x00, SBRV is 0x8400 and SFSA 0x31

STM32WB series

Strange. It looks like the SBRV is not aligned with the expected start address of the FUS code which should be 0x08F40000. So, you are not executing the FUS code but some other code. This is why the FUS state cannot be determined. At least the FUS is not running.

To activate it, you may have to send the command START FUS twice and then check whether the SBRV is aligned with the start of the FUS code.

Unfortunately, FUS don't start even sending multiple START FUS or GET_FUS_STATE commands, it keeps returning error 0xFF (unknown), even using cube programmer (FUS_STATE_ERR_UNKNOWN: Unknown error)
