I’ve got a m2 berry with sata drive connected. The os is Raspbian jessie 8.0 V1.1. I want to move the whole os to the sata ssd and want to boot from the sata disk. I’ve tried different tutorials but every time I get stuck because I can’t find the /tmp/boot/uEnv.txt file. I followed this tutorial banana-pi-boot-your-rootfs-from-sata. Are this tutorials for a different os?
