Problem with STM32CubeProgrammer version 2.16.0 and STM32G0B1xx USB DFU

[CHoog.1]

Hello, there is a problem with programming STM32G0Bxx/B1xx/C1xx using  STM32CubeProgrammer version 2.16.0 

A have a HEX file starting at address 0x8001800 and with length 0x32800.

When programming this using USB DFU, the tool first starts to erase some of the sectors first.

Which is what i expect. Only the number of sectors and the address go wrong. See part of log of the tool:

"14:38:58 : Size : 202.00 KB
14:38:58 : Address : 0x08001800
14:38:58 : Erasing memory corresponding to segment 0:
14:38:58 : Erasing internal memory sectors [1 51]
14:38:58 : erasing sector 0001 @: 0x08000800 done
14:38:58 : erasing sector 0002 @: 0x08001000 done"

As the sector size is 2K for this MCU type, it should erase sector 3 to 103 (or 102)!

And it should start at address 0x80001800!

Please fix asap.

Something similar was already reported by my colleague.

Thanks,

Regards,

Corné

Hello @CHoog.1 

Sorry for the late replay. I'm not able to reproduce this behavior on my side (with both GUI and CLI):

Could you please share your .hex file and your device ID so that we can test it.

Best Regards.

Bumb, We see the same problem with our firmware...

Lets get a fix quickly please..

Can you give more details and share your .hex file and the MCU that you are using.

Best Regards.

STM32G0B1KC is the exact type of the MCU i am using.

When programming a hex file, not starting at 0x8000000 you immediately see the problem with the erases send before the actual programming starts.

Also when just easing individual sectors, you see an error in the calculation of the 'Progam Counter' as the value is called. The value send with the FDU_DOWNLOAD command with wValue = 0 is calculated wrong.

And maybe there is something wrong with the size of the sector. The flash sector size of this MCU is just 2Kbyte.

Not the 4K as shown on that Erase & Programming menu.

As you can see the start address of the erase is wrong. Also the end address and the nr of sectors erased is wrong.

The data in the hex file ends at 0x8034000 (not at 801A000)

Hello @CHoog.1 

Could you please share your .hex file.

Please send me an email or something i can send the hex file to? (something more private)
