CubeCell remote debugging possible?

Hello all,

I read CubeCell is based on ARM Cortex M0+. This platform has builtin remote debug capabilities. Also the Heltec chip has the minimal necessary pins routed outside (16/17 aka GPIO06/07) that provide the needed SWD_DATA/SWD_CLK signal.

I know that feature from ESP32 and STM32 chips and it is so much more efficient than using serial.print() …

Anyone using this with gdb and is willing to share how to set this up?
Heltec, maybe you could support this along with PlatformIO or Eclipse or … whatever?

Best Regards,
