CubeProgrammer firmware upgrade, Error: firmware not authentic (P-NUCLEOWB55)

Javier1 · ‎2021-09-08

I am trying to follow this video: because i think i bricked my coprocessor (m0+ ), same thing happens in two different boards.✌�?

STM32WB Getting Started Series: Part 9, Stack Loading

https://www.youtube.com/watch?v=wheGvdXsi4o

When i click firmware upgrade

\STM32Cube\Repository\STM32Cube_FW_WB_V1.12.1\Projects\STM32WB_Copro_Wireless_Binaries\STM32WB5x\stm32wb5x_BLE_Stack_full_fw.bin

i get this Error: Firmware not authentic!the firmware start addr in the video is outdated, with fw v1.12.1 the correct addr is 0x080CA000 but still same result:

>Please use the CubeProgrammer V2.8 version which ahs the "Start FUS" button and is able to read the FUS state even via the SWD port. This was not the case with version 2.6 or earlier.

I am using a 2.6 version (7months old), i missed the two last updates ,my bad.

I downloaded the 2.8 version all buttons are there.

>“Firmware not authentic�? error message can absolutely result from the fact that an old version of FUS is installed on your board with an old decryption key that does not match a new one used to encrypt the new FW stack .

It sounds plausible,thanks this solves my issues

I'm having a similar issue...

https://community.st.com/s/question/0D53W00001Fmu49SAB/unable-to-successfully-load-ble-firmware-because-of-fusimagenotauthentic-so-my-code-is-failing-in-shcic2bleinit

I tried reverting back to 1.0.2 but it just tells me that I already have a newer version installed.

@Remi QUINTIN , if I have one of those old decryption keys that does not match the new stack how do I update that key?

@DPars.2 what version of cubeProgrammer do you have? my problems were solved by upgrading to latest version

Thank you for the response @Javier Muñoz . I am using CubeProgrammer v2.9. I did notice that my command line programming was still using an earlier version so I updated that but it didn't change anything.

One thing I did notice during command line programming that I hadn't be before is that for the STM32WB5xxE (512K part I'm using) the FUS for 1.12.1 is supposed to be placed at 0x0807A000. I'm loading stm32wb5x_BLE_Stack_full_fw.bin which is 170804 bytes so it takes up 42 memory segments. If I place it at the recommended location of 0x08056000 it erases and programs through section 0x0807F000. Obviously this just writes over the FUS code. So I moved the BLE firmware to 0x0804F000 so that it ends before the FUS. It actually worked on one of the boards that I'm having an issue with but on a couple of others I'm not getting a flash write error (FUS_IMAGE_WRTERROR).

Here's the command line printout:

I actually don't think this is how this works, but I was able to successfully write the BLE firmware by trying different start addresses and different size files (full, light and basic versions of BLE).

@DPars.2 im afraid i cannot help you here

I worked on this issue briefly 2 months ago, gladly never had to come back to it.

I hope you the remaining two boards, stm32's BLE developing experience is a bit messy

Found a solution that worked

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

"I have solved it with a full chip erase. I think it was the option byte nSWBOOT0 set to 1 before the update."

this worked for me and I was starting with 0.5.3 (although a full erase removes that 😉
