I have a P-NUCLEO-WB55 and I would like to update the FUS (currently v0.5.3). However, I keep getting that the firmware is not authentic...

I have followed the steps detailed in the release notes, but both using the GUI and the CLI I still get the error about the firmware being not authentic (despite having downloaded it from ST's website).

Here's the log from the CLI:

./STM32_Programmer_CLI -c port=usb1 -fwupgrade /home/rob/Downloads/stm32/STM32Cube_FW_WB_V1.12.0/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x/stm32wb5x_FUS_fw_for_fus_0_5_3.bin 0x080EC000 firstinstall=0

What am I doing wrong?

Thanks a lot in advance!

Hello @RRob.746​ and welcome to the Community :)

Try set RDP option byte to 0xBB (level 1) and back to 0xAA (level 0). Then, upgrade the FUS.

I advise you to have a look at this AN5185 on the table explains possible errors.

I'll be waiting for your update on this post.
