Read FUS info: works (see screenshot)
Neither firmware deleting nor Firmware upgrading is possible with my STM32WB55 Nucleo board.
Always receiving FUS_STATE_ERR_UNKNOWN.
Can you please advise how to proceed?
Below you can find the option bytes of the board:

Hi @STTwo-32 ,
thanks for the quick response. Sorry, but you may haven't fully read my post "Neither firmware deleting nor Firmware upgrading is possible". I tried updating with STM32CubeProgrammer GUI:
and also with the CLI tool (see below). Seems that uploading (1.step of FUS) works but starting the firmware (2.step of FUS) always fails with FUS_STATE_ERR_UNKNOWN.
Meanwhile I read some other posts and found that FUS_STATE_ERR_UNKNOWN is maybe an issue with "ESE bit set"?
