Could not start GDB process while debugging Zephyr Blinky build on NUCLEO-WL55JCx

Dear All,

Please find issue report I'm experiencing with coretx-debug v1.12.1 using it with VSCode v1.88.1 under Ubuntu LTS v22.04 with NUCLEO-WL55JCx board when trying to run \sample\basic\blinky demo from zephyr-sdk-0.16.5-1

Describe the bug

NUCLEO-WL55JCx is working fine with STM32CudeIDE, have updated STLINK debugger to V3J14M5. Zephyr-SDK installation is working fine with FRDM-K64F boards with VSCode using MCUXpresso plugin. I can also flash and manually GDB debug Blinky example on NUCLEO-WL55JCx board with west. west flash and west debug all work are expected using "openocd" version 0.11.0+dev-00728-gb6f95a16c (2024-02-17-23:51) from Zephyr SDK.

But I can't do source level debugging using cortex-debug neither with "stlink" nor with "openocd"

To Reproduce Steps to reproduce the behavior:

Start debug session
See issue

Expected behavior

I expect to be able to do source level debugging of Zephyr blinky demo on NUCLEO-WL55 board but instead I'm getting this error: Screenshots

I added the following to Zephyr.code-workspace after reading https://github.com/Marus/cortex-debug/issues/598, but it did not helped. Adding it to launch.json makes no difference.

Both outputs are fundamentally the same

Additional context

Manual execution of of the following works as expected. I do get all symbols and version info

~/zephyr-sdk-0.16.5-1/arm-zephyr-eabi/bin/arm-zephyr-eabi-nm --defined-only -S -l -C -p /home/XXXXXXX/zephyrproject/zephyr/samples/basic/blinky/build/zephyr/zephyr.elf > nm.txt

both produce about 50kb files

~/zephyr-sdk-0.16.5-1/arm-zephyr-eabi/bin/arm-zephyr-eabi-gdb -q --interpreter=mi2

produce the following output
