Nucleo STM32WB55: Firmware delete and Firmware Upgrade fails with FUS_STATE_ERR_UNKNOWN

[Rena Z.]

Start FUS: works
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:

Hello @Rena Z. 

According to your screenshot, SBRV is equal to 0x3D800 that indicate FUS v0.5.3 is running on your board. So, you must update the FUS using the stm32wb5x_FUS_fw_for_fus_0_5_3.bin binary.

Best Regards.

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"?

Hello @Rena Z. 

When it fails on the first time on the firmware starting, can you try again by clicking on the "Start FUS" Button. It may fail on the first time. 

Best Regards.
