ROCK Pi 4C Plus can not direct boot from SSD, you need to plug the SD card for bootloader and kernel, rootfs can be put on the SSD. To do that,

  1. boot from SD card with SSD attached, as you do now

  2. write the image rockpi-4cplus-ubuntu-focal-server-arm64-20220520-1242-gpt.img.xz to SSD with:

    xzcat rockpi-4cplus-ubuntu-focal-server-arm64-20220520-1242-gpt.img.xz | dd of=/dev/nvme0n1

  3. use parted to delete the rootfs partition in SD card.

    parted /dev/mmcblk0

  4. reboot, you will boot from SSD now
