Installation

1. Patch U-Boot
   You can patch U-Boot by rel_u-boot_patch_20230719.zip on Stock OS
2. Make bootable MicroSD for Linux OS

a). Reserve 8MB in head for kernel image
b). Create Partition 1 with FAT32 format
c). Create 'root' and 'dev' folders in root of Partition 1
d). Copy 'mininit' to root of Partition 1
e). Copy 'rootfs.squashfs' to root of Partition 1

3. Flash kernel to MicroSD

$  sudo dd if=arch/arm/boot/uImage.xz of=/dev/sdX bs=1K seek=8

 

Linux and Stock OS

It boots into Linux OS if user presses SELECT button when power on. By default, it goes into Stock OS if without SELECT pressed.
