+Serial console:
+---------------
+RockPi-N8 has a 40-pin GPIO header. The pin layout is as follows:
+
+pin 6: gnd
+pin 8: tx
+pin 10: rx
+
+Baudrate for this board is 115200.
+
+The boot order on rockpi-n8 is emmc, sd. If emmc contains a valid Image, the board
+always boots from emmc. To boot from SD, erase emmc as per the guide:
