Flashing
Here is an example for the Hello World application.
On board debugger Nu-link2 can emulate UART0 as a virtual COM port over usb, To enable this, set ISW1 DIP switch 1-3 (TXD RXD VOM) to ON. Connect the NuMaker-M3334KI to your host computer using the USB port, then run a serial host program to connect with your board. For example:
$ minicom -D /dev/ttyACM0
# From the root of the zephyr repository
west build -b numaker_m3334ki samples/hello_world
west flash
Debugging
Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b numaker_m3334ki samples/hello_world
west debug
Step through the application in your debugger.
VS Code Support
Here is to go through VS Code instead of command line.
