Building
Applications for the it8xxx2_evb board configuration can be built as usual
(see :Zephyr Getting Started Guide 2):
west build -b it8xxx2_evb
Flashing
In order to upload the application to the device, you’ll need our winflash tool and download board. You can get the winflash tool at here:Download Link 1 Use the winflash.exe tool to program a zephyr application to the it8xxx2 board flash.
Debugging
Supporting uart debug, currently.
