Programming and Debugging
Applications for the raytac_mdbt50q_db_33/nrf52833 board configuration can be
built, flashed, and debugged in the usual way. See Building an Application and
Run an Application for more details on building and running.
Note
Flashing and Debugging Zephyr onto the raytac_mdbt50q_db_33/nrf52833 board requires an external J-Link programmer. The programmer is attached to the J1 or J9 SWD connector.
Flashing
Follow the instructions in the Nordic nRF5x Segger J-Link page to install and configure all the necessary software. Further information can be found in Flashing. Then build and flash applications as usual (see Building an Application and Run an Application for more details).
Here is an example for the Hello World application.
Use a USB to TTL converter to connect the computer and raytac_mdbt50q_db_33/nrf52833 J10 connector. Then run your favorite terminal program to listen for output.
$ minicom -D <tty_device> -b 115200
Replace <tty_device> with the port where the USB to TTL converter
can be found. For example, under Linux, /dev/ttyUSB0.
Then build and flash the application in the usual way.
# From the root of the zephyr repository
west build -b raytac_mdbt50q_db_33/nrf52833 samples/hello_world
west flash
Debugging
The raytac_mdbt50q_db_33/nrf52833 board does not have an on-board-J-Link debug IC,
however, instructions from the Nordic nRF5x Segger J-Link page also apply to this board.
Use the Debug out connector of nRF52x DK to connect to the J1 connector, and use SEGGER
J-Link OB IF to debug.
