Unable to start latest GDB Server

[tapioreijonen]

When using gcc-arm-none-eabi-10.3-2021.10-win32.exe the GDB debug session start as expected.

When using latest gcc-arm-11.2-2022.02-mingw-w64-i686-arm-none-eabi.exe the GDB debug sessio does not start. Here is copy/paste from the debug console: Reading symbols from C:\Program Files (x86)\Arm GNU Toolchain arm-none-eabi\11.2 2022.02\bin\arm-none-eabi-objdump.exe --syms -C -h -w C:\Projects\git-aws\git-aws-clean\tier2-wxt-aqt\build-bmu801\gcc\projects\BMU801\tier2-wxt-aqt.elf Reading symbols from c:/program files (x86)\arm gnu toolchain arm-none-eabi\11.2 2022.02\bin\arm-none-eabi-nm.exe --defined-only -S -l -C -p C:\Projects\git-aws\git-aws-clean\tier2-wxt-aqt\build-bmu801\gcc\projects\BMU801\tier2-wxt-aqt.elf Launching GDB: "C:\Program Files (x86)\Arm GNU Toolchain arm-none-eabi\11.2 2022.02\bin\arm-none-eabi-gdb.exe" -q --interpreter=mi2 "C:\Projects\git-aws\git-aws-clean\tier2-wxt-aqt\build-bmu801\gcc\projects\BMU801\tier2-wxt-aqt.elf" Set "showDevDebugOutput": true in your "launch.json" to see verbose GDB transactions here. Helpful to debug issues or report problems Launching gdb-server: "C:\Program Files\SEGGER\JLink\JLinkGDBServerCL.exe" -singlerun -nogui -if swd -port 50000 -swoport 50001 -telnetport 50002 -device R7FA4M2AD Please check TERMINAL tab (gdb-server) for output from C:\Program Files\SEGGER\JLink\JLinkGDBServerCL.exe undefined GDB Server Quit Unexpectedly. See gdb-server output for more details.

If I start GDB server manually using same command line parameters ("C:\Program Files\SEGGER\JLink\JLinkGDBServerCL.exe" -singlerun -nogui -if swd -port 50000 -swoport 50001 -telnetport 50002 -device R7FA4M2AD), the GDB server start as expected.

You can see the exact GDB command line and the command line for JLinkGDBServerCL.

Looks like a bad/incomplete install of gdb.

Run them in a Terminal/Cmd.exe and see what you get.

After more investigating of this issue I find this:
