One wrong letter and your linux system is gone, stay on your toes. On my system, my card reader automounts as "sdc".
This does run, talking to the serial console at 115200 baud. I interrupt the boot sequence (which goes noplace since I have nothing but U-Boot on the SD card and no network cable attached.) I type:
setenv bootaddr 0x40000000 boot_kyu=echo Booting Kyu via dhcp ; dhcp 0x40000000; go 0x40000000 setenv bootcmd run boot_kyu saveenvTo discover the MAC address used by U-Boot, type:
printenv ethaddr ethaddr=02:20:a1:5a:xx:yyAfter doing this and adding an entry in my DHCP server for this mac address, it works just fine to network boot an orangepi executable, which actually runs pretty well on the Nanopi.
