STM32WB55 FUS issue ==> firmware not authentic or reconnexion issue during upgrade

[bboulet]

Hello,

I' trying to update the FUS on my STM32WB55CG (1M), I have the latest STM32Cube_FW_WB_V1.3.0, I followed the Release_Notes in the STM32WB_Copro_Wireless_Binaries :

for information I use this chip on my own board (not a nucleo)

I switched the MCU in bootloader

then

• STEP 3 : Delete current wireless stack :
  • STM32_Programmer_CLI.exe -c port=usb1 -fwdelete

then

STEP 4 : Read and upgrade FUS Version

• STM32_Programmer_CLI.exe -c port=usb1 -r32 0x20030030 1
  • 0x20030030 : 00050300 : FUSv0.5.3 => Must be updated using STEP 5.
  • 0x20030030 : 01000100 or 01000200 : FUSv1.0.x => Up to date, you can download the new wireless stack using STEP6.

so I need to update it

STEP 5 : Download new FUS :

• STM32_Programmer_CLI.exe -c port=usb1 -fwupgrade [FUS_Binary] [Install@] firstinstall=0

in my case

STM32_Programmer_CLI.exe -c port=usb1 -vb 2 -fwupgrade stm32wb5x_FUS_fw.bin 0x080EC000 firstinstall=0

I increse the verbose mode to 2 (I join the log file flash_FUS_VB2)

most of the time the upgrade fail during the reconnecting process after Deleting firmware...

if this part pass I have a firmware not authentic at the end

Reconnecting...

Reconnected

Reconnected !

sending an abort request

setting the address pointer to address: 0xffff0054

sending an abort request

FUS state is FUS_UPGRADE_ONGOING

FUS status is FUS_IMAGE_NOT_AUTHENTIC

Error: Firmware not authentic!

and obviously because of this I can't upload the BLE stack.

Your help would be really appreciate, we have a nice project based on this and we would like move forward on this topic.

regards,

Benjamin

I'm having the same problem. despite everything I still do not get results. you solved the problem by pulling the boot pin to the VDD. I tried but did not. Is there a solution you can offer?

Same here!

Here's my full version log:

Notice 0x20030030 : 00050300 (FUSv0.5.3 => Must be updated using STEP 5.), yet getting the same error!

Here's the last section of the upgrade log:

It would be really nice if someone could help us getting our controllers upgraded.

v0.5.3 can not directly upgrade to v1.1.0, first upgrade to v1.0.2, then upgrade to 1.1.0.
