How to fix "Old firmware delete failed" error while trying to firmware update?

[DImre.1]

I tried to update the firmware on P-NUCLEO-WB55 devboard, but it fails with the following error:

"Error: FUS_STATE_ERR_UNKNOWN

Error:

Old Firmware delete failed"

I check in STM32CubeProgrammer, and I have V.0.0.0 version:

 

I do not know why it happened, maybe a previous incorrect way of upgrade process.

Any idea how can I resolve it?

Additional info:

The dongle is ok, I could update it via USB, it has fw V1.1.2.0 version.

This means the FUS is not activated.

Using cube programmer v2.8, you can start the FUS using the "Start FUS" button.

What is the port used to connect to your board?: USB or SWD (ST-LINK) port?

[DImre.1]

SWD (ST-Link) port.

[Remi QUINTIN]

OK.

So be sure to activate the FUS and then read the FUS again.

please provide a log of the FW installation if it fails again.

I attached the log from STM32CubeProgrammer.

from command window:

Could you try in USB DFU mode?

How old is your Nucleo board?

Is it the first time you tried to upgradde the FUS?

Could you give me the value of the SFSA and SBRV option bytes?

--> I do it now, and will give you feedback.

How old is your Nucleo board?

-->first time it is used, unpacked yesterday. No idea when it was manufactured, but on the sheet in the package I see July 2019.

Is it the first time you tried to upgradde the FUS?

--> yes.

Could you give me the value of the SFSA and SBRV option bytes?

-> value of SFSA: val0xd0, addr: 0x080d0000, SBRV: 0x34000

[Remi QUINTIN]

Nothing strange regarding the option bytes.

Can you launch a FW delete command?

[DImre.1]

No, because as I wrote earlier, the error message is:

"Error: FUS_STATE_ERR_UNKNOWN

Error:

Old Firmware delete failed"

via ST-LINK. Via USB only the dongle I can see, and the command is working. At that point I'm little bit uncertain because I did not see any info regarding the need for dongle upgrade.

[DImre.1]

It looks like the old firmware is damaged and cannot be recognized. One solution would be to directly flash the memory with the fw file. Ignoring the old firmware error issue.

[Remi QUINTIN]

But The SFSA = 0xD0 which means there is a FW already and still installed on the board!!!

It is not deleted.

I assume that your board configured in USB DFU mode (with a jumper set on CN7 position (67 + the USB USER connector) is not discovered by CubeProgrammer because nSWBOOT0 = 0 while it should be set to 1 for the USB DFU mode.

--> I assumed it, because I never could delete it. Looks like it is damaged.

--> I tried it now, but the error is after trying to connect:

[Remi QUINTIN]

I am afraid you won’t be able to flash a recent version of the FW with an old version of FUS.

I am quite puzzled by your issue.

Could you try with CubeProgrammer version 2.8?

[DImre.1]

I'll do and will give you feedback.

[Remi QUINTIN]

I want to correct my statement regarding the USB configuration : the jumper must be set on position 5-7 on CN7.

Have a look at the attached document.

[DImre.1]

Don't worry, I did the same from the beginnging. :)

[Remi QUINTIN]

I am out of idea. Your board is a weird state with a FUS potentially impacted.

The only lame recommendation I can give you is to try with another Nucleo board.

[DImre.1]

Remi, thank you for your help! :)
