From postmarketOS Wiki
Revision as of 10:44, 26 October 2018 by JLIT99 (talk | contribs)
Warning WARNING: This device is not recommended for future use with postmarketOS due to its armhf architecture. Alpine Linux (the distribution that postmarketOS extends) pmaports#599 has been considering dropping it.
The processor of the device may support the armv7 architecture. If so, you can modify the device package and change the architecture accordingly.
This device is marked as not booting.
Status: Need novacom packaged for Alpine

NOTE

None of this work has been (merged/pushed/get correct terminology) upstream. Contact CmdrWgls on IRC if you're interested in working on it before he gets around to actually doing so.

What works

  • Nothing

What doesn't work

  • Everything

Progress

  • boot.img extracted from Evervolv nightly Android ROM
  • determined that boot.img is vmlinuz and not an Android boot image
  • successfully compiled novacom (and its dependencies)

Next steps

  • package novacom for Alpine
  • build device-hp-tenderloin
  • find a kernel and compile it
  • package kernel and boot image following these instructions

Flashing/booting

It looks like the actual boot process on the touchpad is just uBoot. We only need to package novacom for alpine to push images to the boot partition of the device.

Novacom sources can be found here. The specific repo and dependencies are as follows:

We can probably use the novacom pkgbuild from the AUR in alpine: https://aur.archlinux.org/packages/palm-novacom-git/

We might also need novacomd, not sure yet.
