Progress

Can boot into a mainline linux kernel, but the bootloader isn't persistent so it can only boot tethered.

Booting

  1. Install syringe package in chroot
  2. Enter DFU mode (hold power and home with USB connected to computer)
  3. load openiboot
$ loadibec openiboot-ipad1g.bin

expect script for automating booting with oibc:

#!/usr/bin/expect
spawn oibc

send "!/path/to/vmlinuz\r"
sleep 0.1
send "\r"
expect "Received file"
send "kernel \"console=tty0 PMOS_NO_OUTPUT_REDIRECT\"\r"
expect "Done: kernel"

send "!/path/to/initramfs\r"
sleep 0.1
send "\r"
expect "Received file"
send "initrd\r"
expect "Done: initrd"
send "wait_boot 15000\r"
expect "Done: boot"
  • Set console=ttySAC0 for UART console instead of framebuffer
  • earlycon=s3c2410,0x82500000 and keep_bootcon may be useful too.
