Debug session doesn’t launch
Software Development Kits > Troubleshooting
After pressing the Run and Debug the Terminal output for the Pre-Debug task shows Status: SUCCESS, but nothing happens!
For the 2.0.x release, there is a known bug with the way OpenOCD is configured for debugging. This is fixed in 2.1.x onwards.
External debugging tools are recommended for 2.0.x. The MM-IoT-SDK installs OpenOCD into the .platformio/packages/tool-openocd directory of the user's home directory, and can be used externally to run a gdb server to connect gdb to the device.
