Build & Debug

./scripts/rollup.sh
cd build
make clean all
make flash

Analyze *.elf file

make elfread
make elfsize

# Run both above commands.
make analyze

On-chip debug using GDB

First, start OpenOCD server:

make openocd

Then, run make gdb in another terminal.

make gdb

Or, run make debug to automate the above two commands:

make debug

Lint
