Problem with STM32G0B0: failed to download Segment[0]

I have a Nucleo board with a new MCU, base board is the Nucleo-G070RB. Now it is a ST link with a STM32G0BORE.

I have a problem with the internal bootloader where i cannot upload a new program via USB DFU.

There is no hardware problem because VCP works just fine. No data corruption of something.

I have tried .HEX .BIN and .ELF all have the same problem.

This is the error log is have:

Hi @PieterInHetBos,

Can you please check Option Byte setting?

Try this workaround: Force to erase 'entire flash' memory, before start debugging.

Can you please share the Option Bytes parameters and the log file, in order to investigate the issue.

Hello @PieterInHetBos​ and welcome to the Community 🙂

Could you please try to use STM32CubeProgrammer on standalone.

Make sure to use latest release of CubeProgrammer, and try to upgrade ST-LINK firmware.

Check the registers and ensure that “flash empty�? is not causing such issue.

I advise you to erase the flash memory first.

A code, which expects a 255-byte alignment, is definitely broken:

Hello Imen,

Thank you for your reply.

I have updated CubeProgrammer to V2.13 and CubeIde V1.12. I have updated the STLink firmware. I also have erased the memory everything is filled with FFFFFF.

What needs to be the Option Bits on the STM32G0B0RET?

Hi Imen,

It seems that the 0x467 loader is really broken. The bigger problem is that CubeIDE is also relying on it to load the program before debugging, and it is now impossible on some of the G0 devices.

This must be fixed as soon as possible...

Best regards,

Kraal

Hello Imen,

I have downgraded to STMCubeIDE to 1.7 with STMCubeMX 6.3 and STMCubeProgrammer 2.8. This fixed all the problems. Please fix the new software so we can use the updates

Dear Imen,

Any luck on a update?

Hi @PieterInHetBos​ ,

The fix is integrated and will be published in the STM32Cubeprogrammer v2.14.0.

But, for the moment I can't give you any information about delivery date.
