FUS_STATE_IMG_NOT_AUTHENTIC error updating FUS from 1.1.0 to 1.2.0 on STM32WB5MM-DK

[NS.123]

Hi All,

I am getting the error FUS_STATE_IMG_NOT_AUTHENTIC while updating FUS. I am using the provided image in:

STM32Cube/Repository/STM32Cube_FW_WB_V1.12.1/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x/stm32wb5x_FUS_fw.bin

Any hints are welcome!

Thanks,

Cheers,

Thanks NS.123 this worked well. I was having issue with USB connection and getting "Error: firmware not authentic" so switching to stlink and I was getting FUS_STATE_IMG_NOT_AUTHENTIC. Finding you solution made my day.
