Unable to debug with FreeRTOS awareness enabled

Hi there,

Up until recently I was able to debug fine using the following config:

                "name": "X Debug Release",
                "cwd": "${workspaceFolder:X}",
                "executable": "${workspaceFolder:X}/project/X/build/release/X.elf",
                "request": "launch",
                "type": "cortex-debug",
                "servertype": "jlink",
                "device": "STM32L451VE",
                "runToMain": false,
                "rtos": "FreeRTOS",
                "svdFile": "${workspaceFolder:X}/toolchain/STM32L4x1.svd"

However, recently when trying to launch this config I get the following log: "monitor" command not supported by this target. Removing the line "rtos": "FreeRTOS", allows debugging to launch as usual but without FreeRTOS awareness.

arm-none-eabi-gdb version: 8.3.0.20190709-git JlinkGDBServer version: V6.94a

This was working well up until recently and I’m unsure what has changed. Any help is much appreciated, thanks.

Interesting - as the v6.94 doesn’t break it in general for all FreeRTOS versions - but certainly seems to have issues with that particular one. On our side, we can’t do anything about it as it just seems to crash the GDB server - which at that point puts it out of our hands. Glad you found a work-around.

Interesting find @Marus. However, I just manually downgraded the jlink-software-and-documentation package from version v6.94 to v6.88a (a version that I found I had working in the past) and thread aware debugging is working again. Unfortunately without going through all the versions in-between I would be hard pressed to tell you which version of the package broke things.

Thanks for having a look at this.
