Zephyr RTOS aware debugging with RT1020

Hi there,

I just started working with a mimxrt1020 dev board. PlatformIO seems to work fine with Zephyr, I already created a small application to blink the internal and an external LED with two separate threads.

For flashing/debugging i use the on board Jlink debugger. But here comes the issue:

How do I debug with RTOS awareness? I don’t see the two different threads. I only get errors if I try to set breakpoints.

I googled around but did not find a solution. Do I need an external debugger? How do I correctly configure the debugger? It would be awesome if someone could send some help…

My platformio.ini:

platform = nxpimxrt
board = mimxrt1020_evk
framework = zephyr
debug_tool = jlink
upload_protocol = jlink
monitor_speed = 115200
