Hello CaptainData,
yes, the strings for bootmmc and bootcmd are identical, here it’s just a matter of preference. The only difference is that ESPRESSObin automatically reads variables set in bootcmd on every reboot. In above example, users can simply set and save the bootcmd variable so that ESPRESSObin boots every time from microSD card instead of having to type run bootmmc in U-Boot on every reboot.
