Hello Houda,

As per your suggestion i started FUS

after that i tried to delete so i am facing same issue, another thing we need to observe here that FUS version still showing v0.0.0.0

Hello Remi QUINTIN,

1) while going to option bytes it shows that check the flash protection, and another thing i am not able to connect ST-link utility

2) 8 months back i have purchased

Hi @Ra.1​ ,

can you please confirm The Firmware upgrade is done correctly?

Houda

Hello all,

these are for the reference

Thanks for the download but I am just missing the 2 most important ones: SFSA and SBRV which are part of the security configuration. They do not appear on the first screenshot.

Hello houda,

this is the log which i got after updating

Hi @Ra.1

Can you please share a screenshot with SFSA and SBRV OB which are part of the security configuration as mentioned by Remi QUINTIN?

Houda

The SBRV value is still missing but I have enough info with SFSA = 0xF6 to say that the FUS has never been updated on this board as this address is the one of the very first FUS version v0.5.3. At the opposite, the pre-installed FW has indeed been deleted.

From this constatation, I can say that you will never be able to upgrade the FW with this FUS version. You need first to upgrade it to FUS v1.0.2 first and then to the latest version v1.2.

Then you will be able to program the FW stack on your board.

So we have to focus first on the upgrade to FUS V1.0.2.

Looking at the latest WB FW package v1.12, we should be able to upgrade the FUS in one row, just using the stm32wb5x_FUS_fw_for_fus_0_5_3.bin file.

stm32wb5x_FUS_fw_for_fus_0_5_3.bin

• Firmware Upgrade Services (FUS)
• This binary is the utility to flash the Wireless Coprocessor Binaries.
• Latest version of the FUS to upgrade board containing only FUS v0.5.3

So try to update your board with this binary file. Then you should have the SFSA value set to 0xF4. Then program the RF stack you need on your board. It should work.

Hello,

sorry for late response, i tried with both the files which you have suggested stm32wb5x_FUS_fw_for_fus_0_5_3.bin, stm32wb5x_FUS_fw_1_0_2.bin

but getting same error as shown in below screen shot
