Coreboot/GRUB2 on Pinebook Pro?

[u974615]

Is there work on being able to replace uboot with coreboot on the Pinebook Pro? 

I know coreboot/depthcharge (payload) would work for ChromeOS pn Pinebook Pro, but what about coreboot/GRUB2(payload) for Pinebook Pro?

Alexander Graf (SUSE) has some interesting talks regarding GRUB2 and UEFI on ARM:

Libreboot won't touch this device

I wish someone would.

Alexander Graf has a repo for GRUB2 ( arm with thumb and arm64? ) on GitHub: https://github.com/agraf/grub, but I assume that is for uboot.

Can we just use this? https://linux.die.net/man/8/kexec

Or this: https://github.com/open-power/petitboot/

Yes for Petitboot, being able to boot to a newer kernel without "reflashing" is the desire...or use an older one if the newer one fails.

kexec would be used once an intermediate kernel could be loaded as a payload. It is my understanding Coreboot had its origins from LinuxBIOS, which does this.

Petitboot looks interesting

Librecore too

There is even Petitboot package for Ubuntu, so I installed it, but don't know how to configure it.

I tried kexec, but armhf is not supported.

Petitboot may be posted on odroid (N1?) forum.

Try here: http://git.ozlabs.org/?p=petitboot for source code and build instructions separate from the Ubuntu package.

I understand "ARM64 with ACPI" to mean "ASUS Chromebook C201" the Rockchip RK3288 SoC

boards: bob and scarlet use the same SoC as Pinebook Pro ( Pinebook Pro's mainboard doesn't seem to be listed/supported. )

The ASUS Chromebook CT100 seems to be a variant of the gru mainboard, as scarlett is not listed.

I believe gru and kevin do too.
