failed to start GDB server

Hello everyone,

I am facing a flashing/debugging issue with the STEVAL-SPIN3202 Rev 3.1 board.

Board:
STEVAL-SPIN3202 Rev 3.1

Software Used:

• STM32CubeIDE

• STM32CubeProgrammer

Problem:
While trying to flash or debug the board from STM32CubeIDE, I get the following error:

"Failed to start GDB server"
"Error in initializing ST-LINK device"
"Failed to connect to device"

Also, in STM32CubeProgrammer:

• Read data operation fails

• Target connection sometimes not detected

Additional Observations:

• ST-LINK USB is detected intermittently

• Board LED becomes dim/slow ON sometimes

• Reinstalled STM32CubeIDE and drivers

• Installed ST-LINK drivers

• Tried different USB cables and USB ports

• Tried lower SWD frequency

• Tried Hot Plug mode

• Tried BOOT0 method

• Still unable to flash or read target

I would appreciate guidance on:

1. Correct jumper settings for STEVAL-SPIN3202 Rev 3.1

2. Whether onboard ST-LINK firmware may be corrupted

3. Possible hardware protection/reset issue

4. Correct power supply requirements during flashing

Thank you.
