Programming and Debugging
Flashing
The byteSENSI-L board can be flashed with the SEGGER JLink programmer.
You can build and flash applications in the usual way. Here is an example for the Hello World application.
west build -b bytesensi_l samples/hello_world west flash
Debugging
Debugging your application can be done with west debug.
Serial console
The byteSENSI-L board only uses Segger’s RTT console for providing serial console. There is no physical serial port available.
