How to write the SD card
========================

Once the build process is finished you will have an image called "sdcard.img"
in the output/images/ directory.

Copy the bootable "sdcard.img" onto an SD card with "dd":

  $ sudo dd if=output/images/sdcard.img of=/dev/sdX bs=1M conv=fsync

Insert the micro SDcard in your Nanopi R3S and power it up.
The console is on the serial line, 1500000 8N1.
