Flashing Image to the SD Card

First, partition your SD Card into boot and root. Then flash the corresponding image into the partition:

sudo dd if=deepin-eic7700-riscv64-25-desktop-installer.boot.ext4 of=/dev/sdd1 status=progress
sudo dd if=deepin-eic7700-riscv64-25-desktop-installer.root.ext4 of=/dev/sdd2 status=progress

Finally, Insert the SD card into the card slot shown with No.1 of figure 1.

Flashing Image to the SATA M.2 SSD
