Run Linux from an SD card with RFS on a USB

Additional flexibility in running Linux from an SD card on a RK3288 device through the ability of having the Linux root file system on a USB.

The following script allows you to create the bootable SD card on a Linux PC giving you the advantage of being able to:

- Experiment more freely with kernel/resource alternatives
- Use a know working RFS

It uses a standard boot image and parameter file and comes with a default generic RK3288 Linux kernel and resource image which you can replace as required.

Download the file from https://drive.google.com/file/d/0B99O3A0dDe67NDNadVN0NHJObHM and uncompress it to get the script and supporting files.

First check your bootloader version and if necessary flash the RK3288Loader_uboot_V2.17.02.bin to your device to allow SD card booting.

Then insert an SD card and enter:

./create-linux-sdcard-usb

The last step is to put the Linux RFS on a USB.  As a starter you can download one of the examples in the 'downloadable-rfs-examples' file and write to USB using 'dd'.

Then insert your SD card and USB into your RK3288 device and power up to enjoy Linux.
