Programming and Debugging

The rts5817_maa_evb board supports the runners and associated west commands listed below.

	flash	debug
rtsflash	✅ (default)

Building

Build Hello World application as you would normally do.

# From the root of the zephyr repository
west build -b rts5817_maa_evb samples/hello_world

The file zephyr.rts5817.bin will be created if the build system can build successfully. This binary image can be found under file “build/zephyr/”.

Flashing

Short the two pins of J6 to enter force rom mode (see RTS5817MAA_EVB_User_Guide [1]).
Connect the board to your host computer using USB.
Use west flash command to flash the image.
Disconnect the two pins of J6 and reboot, The Hello World application is running.
