Guidance Required – ST-LINK V2 Not Working After Inverter Board Failure
I need your guidance regarding an issue I encountered while working on the customer inverter board.
While testing the board, I applied a sudden ramp-up in open-loop mode. Due to the high current spike, the inverter board got damaged, which I understand and accept.
However, I had an isolated ST-LINK V2 connected to the board during the test. Since then, the ST-LINK is no longer functioning properly. The PC detects the debugger, but when I try to connect or program the target using STM32CubeIDE, it reports that "No ST-LINK detected" or is unable to establish a connection with the target.
Unfortunately, we do not have the schematic of the isolated ST-LINK V2, so I am unable to troubleshoot or repair it further. As the debugger costs around ₹5,000, I would appreciate your guidance on whether there is any recommended procedure to diagnose or repair it, or if it should be sent for service/replacement.
Please let me know how I should proceed.
