NUCLEO-G474RE - Failed to start GDB server

[alw]

Hello,

I can create a simple program in STM32CubeIDE V1.17.0 targeting the NUCLEO-G474RE board. I can build ok but am having problems with the GDB server starting. 

JP5 is set to 5V_USB_STLK and JP (BOOT0) is off. I can do the ST-Link Upgrade without problem, so the USB cable and powering is ok.

I select Run>Run As>STM32 C/C++ Application and get the following. 

STMicroelectronics ST-LINK GDB server. Version 7.9.0

Copyright (c) 2024, STMicroelectronics. All rights reserved.

Starting server with the following options:

Persistent Mode : Disabled

Logging Level : 1

Listen Port Number : 61234

Status Refresh Delay : 15s

Verbose Mode : Disabled

SWD Debug : Enabled

ST-LINK Failed to get target status

Error in initializing ST-LINK device.

Reason: Unknown. Please check power and cabling to target.

Hello @alw ,

Have you tried the latest release of STM32CubeProgrammer?

Dd you change the default Option Bytes with Cubeprogrammer ?

Try connecting in "under reset" mode, then connect the debugger.

Check that the headers/jumpers on the Nucleo are fitted correctly.

Please follow the tips in this article : How to solve connection errors when connecting and... - STMicroelectronics Community

Hello,

Problem solved, it was just JP6 that was missing.
