U-Boot#
Yocto Linux Image
So I used
Etcher to burn a microsd with
cl-som-imx7-image-qt5.sdcard.bz2. Note that P6, the SD Card slot is used for
boot.
Alternatively we can use bzcat:
→ bzcat ./cl-som-imx7-yocto-linux/images/cl-som-imx7-image-qt5.sdcard.bz2 | sudo dd of=/dev/sdd bs=1M ; sync

Ehhhh, I’m a bit scared. I’ll wait.
