Flashing
You can't currently flash via pmbootstrap, but the kernel can be booted via PongoOS.
Follow this guide to get the starting pieces up and running.
Prerequisites
WARNING: Compilation of these tools on Alpine is broken currently. You can get some pre-compiled binaries here. |
- palera1n
- PongoOS
- pongoterm
- m1n1-idevice
- linux-apple dtbs
- Either compiled from the git repo or extracted pre-compiled from the linux-postmarketos-apple package.
TODO: Document extracting dtbs from kernel package. |
$ pmbootstrap init
Select 'apple' for vendor and 'idevice' for codename
$ pmbootstrap install
Optionally enable netboot
$ pmbootstrap initfs hook_add netboot
Get the linux and initramfs
$ pmbootstrap export
Prep the m1n1 bootloader
$ cat path/to/m1n1.bin \
path/to/boot/dtbs/apple/*.dtb \
/tmp/postmarketOS-export/vmlinuz \
/tmp/postmarketOS-export/initramfs \
> m1n1-linux.bin
Use palera1n to boot PongoOS
$ PALERA1N_BYPASS_PASSCODE_CHECK=1 doas palera1n -f -k path/to/Pongo.bin
Boot postmarketOS!
$ printf '/send path/to/m1n1-linux.bin\nbootm\n' | doas path/to/pongoterm
At this point your device should have gone through PongoOS, m1n1, and now be showing the postmarketOS bootsplash!
Netboot
WARNING: Netbooting is broken currently for all devices. For more information look here. |
If you enabled netbooting during the flashing setup you can use it to boot a rootfs. To serve the rootfs, run:
$ pmbootstrap netboot serve
If you see a tty and a login screen, that means pmOS is working! Now you can go through the usual procedures. (Using ssh, getting internet, etc.)
