Unable to upgrade FUS on STM32WB55 (WeAct) / FUS_NOT_RUNNING

[Magal]

I was trying to upgrade the FUS on my STM32WB55CGU6 (WeAct board) using an ST-Link V2, but it keeps spamming errors when I try to "Start FUS":

Or when I try "Firmware delete":

This is what appears when I read the FUS infos:

These are my option bytes:

I have already tried to update using stm32wb5x_FUS_fw_for_fus_0_5_3.bin and it says "Firmware upgrade success", but the errors persist. I tried the other upgrades (stm32wb5x_FUS_fw_1_2_0, stm32wb5x_FUS_fw and stm32wb5x_BLE_Stack_full_fw) after the _for_fus_0_5_3.bin one, but no luck.

I tried using "Start address automatic detection" and also tried placing the address manually (0x080EC000 for the first two FUS upgrades, 0x080EE000for the last and 0x080D0000 for the Stack). Maybe something crashed internally? I mistakenly used the address 0x0807A000 one time too.

Any ideas on how to recover this?

Hello @Magal 

Which version of STM32CubeProgrammer tool are you using?  Which version of the STM32CubeWB firmware package?  Make sure to use the latest releases of used softwares and tools.

Please have a look at this wiki page which describes how to upgrade BLE stack and FUS.

Try using the binary:
