Description:
The chip id is incorrect.

This problem only happens on this nucleo_g0b1 board, I have other boards (F411RE / LoRaWAN boards, etc..) and the chip id is read properly. I unfortunately doesn't have access to other G0 boards to probe if the problem happens on other Cortex-M0+ cores.
I've tested this only with the lastest release (v1.7.0), on multiple machines (Windows 10/11, Arch Linux) and got the same problem everywhere.

PR #1126 doesn't seem to fix my issue as it should be the v1.7.0 Release

I've ensured that the STLink is properly updated, and I can also program the board properly using STM32CubeProgrammer or STM32CubeIDE.

Is there anything else that I can do to help solve this issue ?

Thanks for your support,

Hi, I have the same problem on a custom board with a STM32G0B0RE using an ST-Link V2, STLink tools version 1.7.0 on Windows 10 64-bits:

I don't have this problem on any other board. The chip id is correct but STLink tools version 1.7.0 doesn't recognise it.

Thanks for your support !

Fixed in #1140.
