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.
