Model assertion file for build Ubuntu Core images for the Sipeed Lichee RV.

Install the ubuntu-image utility:

snap install --classic ubuntu-image

Build or download the latest versions of the kernel and gadget snaps from the links below.

Create an image file using the assertion and downloaded snaps:

ubuntu-image snap ubuntu-core-22-sipeed-lichee-rv.model \
  --snap sipeed-lichee-rv-kernel_*-allwinner_riscv64.snap \
  --snap sipeed-lichee-rv-gadget_*_riscv64.snap

The image is generated and saved to the following file: sipeed-lichee-rv.img

Copy the image to an SD card using dd:

dd if=sipeed-lichee-rv.img of=/dev/<path to SD card> bs=4M

Insert the SD card into the device, connect a serial console, and boot.
