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?

Hello,

i have another STM32WB DK which is working so i connected and observed that the value of SFSA and SBRSA is differ from the current (which has issue) DK.

so i tried to change the value so it gave the error "option byte program failure"

[Remi QUINTIN]

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.

[Remi QUINTIN]

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.

[Ra.1]

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

just for confirmation check my board connections as follows

Strange! Could you give us the value for the SFSA and SBRV option bytes?

One point above is the fact that it seems the FUS upgrade looked good, but the SFSA value is still 0xF6.

Could you move to CubeProgrammer 2.8 and read the FUS value with this version?

You may have to press the "READ FUS version" button twice to get the version.

[Ra.1]

Hello,

1) Could you give us the value for the SFSA and SBRV option bytes?

A: i can find SFSA but SBRV not there in that list

2) One point above is the fact that it seems the FUS upgrade looked good, but the SFSA value is still 0xF6.

A: actually at that point i clicked just "START FUS" option but i did not pressed "UPGRADE FIRMWARE" option in it so in log that shows just fus_started_successful

3) Could you move to CubeProgrammer 2.8 and read the FUS value with this version?

A: yes i am using same version

​

4) You may have to press the "READ FUS version" button twice to get the version

A: ​

[Remi QUINTIN]

1) So what is the value of SFSA? Still 0xF6?

Note that the SBRV option byte is in the same "secure" window but you may have to scroll the window down a bit to see it appearing.

2) OK understood.

Could you show me the command you sent to upgrade the FUS with stm32wb5x_FUS_fw_for_fus_0_5_3.bin or stm32wb5x_FUS_fw_1_0_2.bin files?

The addresses should be 0x080EC000 for both.

Note that you may only use stm32wb5x_FUS_fw_for_fus_0_5_3.bin file to upgrade the FUS to the latest version.

[Ra.1]

Hello,

1) Yes i got the SBRV  value as well as SFSA see*2

2) No...i am not updating using cmdprompt just i am clicking the firmware upgrade option see *1

image: *2

[Remi QUINTIN]

For the FUS upgrade , you should uncheck the "Start stack after upgrade" button. I see it seems not active as there is no FW installed but who knows.

SFSA and SBRV option bytes are consistent. The load address is also OK.
