failed to start GDB server

[Charan_sahoo]

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.

Hello ​@Charan_sahoo,

Did you try to upgrade the ST-LINK firmware version using the Firmware upgrade button on the STM32CubeProgrammer tool?

• ST-LINK USB is detected intermittently

Sounds like you have a dodgy cable and/or a faulty USB connector.

Clearly, if the basic USB connectivity is flaky, nothing else which depends upon that connection can ever be reliable!

Hi,

>  Target connection sometimes not detected

thats most time a connection problem, so try : other usb cables, other plug/port ; try not on a hub.

And check in CubeProgrammer : option bytes → look on all sectors , protection is off.
