Some help for running the setup

1. Use ./build.sh to build the challenge docker container
2. Execute it with ./run.sh

Debugging

Using ./run-debug.sh starts the container in debug mode. You can use port 1337 for the usual serial connection. The emulator listens on port 3333 for a GDB connection. Logging from the emulator is available on stdout from the docker container.

To connect to the gdbserver use multiarch or arm-none-eabi GDB:

file docker/gnrc_networking.elf
target remote tcp:localhost:3333

Firmware modifications

Run ./build.sh --firmware to download the git repository and apply the patches. Running ./build.sh --firmware again will create a new image including any modifications. To get back to the initial state use ./build.sh --clean-firmware

Many files have #define ENABLE_DEBUG 0 in the header. Setting this to 1 will enable debugging output for a single file.
