If you’ve already had a Linux system SD card, you can refer to the following steps to
copy the content to the onboard flash and boot from it. Advantech also provides you
with a script “mkinand-linux.sh” to speed up the process of installing a system image
to the onboard flash.
1. Refer to Chapter 3.6.1 to make a Linux system SD card.
2. Insert this Linux system SD card to RSB-4221 and connect serial console.
3. On RSB-4221 platform, type
#root
