How to fix ST-Link Nucleo board unable to connect, where the target is not found and the st-link is showing chipid 0x0000

[JMora.7]

Hello I ordered two NUCLEO boards, to start some projects on the ST32G03 platform. I was using the board with out an issue and connected to am Ubuntu 20.04 sys, updated the firmware on both and now one is working and the other is not, here is an output from dmesg inserting one then the other.

the first one works great and the second one is not able to connect to the g03 board. Here is the output os the st-info probe.

This is from the working one.

This is from the failing one:

This failed only after the firmware upgrade, is there any way to revert this?

You can use the firmware update tool to go to older versions, you just have to download the appropriate one.

V2J35 is still rather OLD

Thank you for your recommendation, I could have sworn I tried that, but I have to double check, Any specific procedure I need to take to ensure this is done correctly? Thank you.

Well, I tried going back to an older firmware and it did not work.
