## Compiling
Simply go to an example and run `make`. If you used the `./build_image` command before (see section "Bootloader"), run a `make clean` before. TODO: Unify the two build options.
Initialize the build-system by running `meson --cross-file card10-cross.ini build/` in the main directory. Then you can build either everything using `ninja -C build/`, or build individual binaries by choosing one of the following targets (`ninja -C build/ <target>`):

## Debugging
After flashing and the initial reset using `mon mww 0x40000004 0x80000000`, you can say `mon reset halt` and then `continue`. You can now debug as usual.

## Serial Console
card10 outputs debug information on the serial console. Baudrate is 115200. The provided USB adapter creates a CDC device (under Linux /dev/ttyACM0). You can use screen to open and view it: `screen /dev/ttyACM0 115200`.
