Compile, Flash & Debug

requirements:

• for compiling: arm-none-eabi-toolchain, gnu-make, git
• for flashing: SEGGER J-Link, JLinkGDBServer (other Debug Probes can be used, see Makefile)

run gdb-server
./gdb.sh

build and flash firmware with static DMX-Address
make program DMX_ADDRESS=99

build and flash firmware with address selector on EXP1
make program

open serial RTT prints:
telnet localhost 9000

open cgdb debugger:
./debug.sh
