sh4twbox-multiboot

This project demostrates the multi-boot setup through UBOOTWPDA and a simple script file (mboot).

We can use mboot and this project's scripts to test multiple OS including sh4twbox, xbmc, debian, Fedora and Arch for NextVOD.

In this document sda maybe sdb if you plug-in external USB on NextVOD. You can use fdisk -l to check it.(This is a known issue of UBOOTWPDA)

Usage for choose boot partition

mount boot partition

You can run fdisk -l to check use sda1 or sdb1. # mount /dev/sda1 /boot ## or # mount /mnt/sdb1 /boot ## or if you have setup /etc/fstab, just # mount /boot Then # cd /boot

Run the menu to choose next boot menu

# ./mboot     <--- enter the menu for boot 
2015/07/10 14:53:36 2_xbmc   <--- current boot partition and its setup time
==Available Boot OS==
1_recovery  2_xbmc      3_debian    6_sh4twbox  7_fedora    8_arch  
=== enter the number:1  <--- enter the partition number (eg. recovery)
... [ omit ] ... <--- display debug information
+ cat ../uboot.sh
... [ omit ] ... <--- display the boot parameters    
+ set +x
Press [Enter] to reboot  <--- press enter will reboot to your new setting

Usage for add a new boot partition

We assume you have installed your OS (eg. buildroot) on one partition (eg. /dev/sda9). And boot to recovery partition.

mount related partitions

Replace the SDX with sda1 or sdb1. # mkdir -p /mnt/sda9 # mount /dev/sda9 /mnt/src # mount /dev/SDX /boot # cd /boot

create new directory

It should following naming rule <partition_number>_<partition_name>. Replace the KERNEL with vmlinux.ub or uImage...

# mkdir -p boot/9_buildroot     
# vi boot/9_buildroot/uboot.sh
# cp /mnt/src/KERNEL boot/9_buildroot

# cd /mnt/src
# mkdir -p boot
# echo "/dev/SDX /boot auto defaults,noauto 0 0" >> /etc/fstab

Installation for mboot script

# mkdir -p /mnt/sda1
# mount /dev/sda1 /mnt/sda1
# cd /mnt/sda1  # to recovery partition

## wget https://raw.githubusercontent.com/dlintw/sh4twbox-multiboot/master/mboot
## because busybox's wget can not get https, we use dropbox's space.
# wget http://www.dropbox.com/s/7pfdvzks3h8clwc/mboot 

# chmod +x mboot
