FUS version v0.0.0

[BertrandM]

Hi,

 

I have a custom board with a STM32WB55RG and I’m trying to upgrade the Wireless stack (and the FUS firmware).

 

When I perform a Read FUS Infos in STM32CubeProgrammer, it returns v0.0.0 value for the FUS Version (I know that it should be v1.2.0 as it used to be v1.2.0).

 

If I read the memory at address 0x20030000 I have the following value:

 

 

where DeviceInfoTable seems valid,  the Wireless stack version is1.15.0 build 3 and FUS version is 1.2.0

 

SFSA value is 0xce (address: 0x080ce000)

 

Any ideas why I see this value (v0.0.0) when I read the FUS infos?

 

Moreover, when I try to update the wireless stack (or the FUS firmware), everything looks to go well but when I read back the FUS infos they are still the old values.

Hello ​@BertrandM 

Did you try with the latest release of the STM32CubeProgrammer V2.22.0?

Try reset the board and reconnected via CubeProgrammer.

You can use Full chip erase in STM32CubeProgrammer, then retry Read FUS.

Hello ​@Imen.D ,

 

Thanks for your reply.

 

Unfortunately, I already use the latest release of STM32CubeProgrammer (v2.22.0).

 

I already tested to reset the board, reconnect, full chip erase and even enable RDP1 then return to RDP0 to force an erase but without success.

But this morning, for unknown reason, it recovered...
