Has anyone been successful in booting from an alternate image on the MicroSD card? Ubuntu, ChromiumOS, Etc.

The miroSD boot should works on the mrfixit2001 Debian OS (Default build). The build check for boot signature on microSD card and pass the boot sequence over to continue booting.

Unfortunately, it does not work properly today.

We work on fixing that now!

The u-boot that resides on eMMC does not set correct `fdtfile=` which is required by my images and `ChromiumOS`.
The `fdtfile=` set by bootloader wrote on eMMC is `evb_rk3399` instead of `rk3399-pinebook-pro`.

As for Chromium OS, I'm also uncertain if u-boot does support i2c4 and if it does have the `CMD_I2C` built-in,
so it is likely that this does not support auto-detection of device that it runs on:
https://github.com/ayufan-rock64/chromiu...oot.cmd#L3

As Chromium OS is dual-boot image, where it during boot detects what device to use.

The only solution today is to disable eMMC or replace eMMC bootloader with mine.

UPDATE:

This is fixed. Update your Pinebook Pro to 1.1 and it should work fine then.

I attempted to boot mrfixit's Debian desktop last night, it hangs early in boot process, got past boot splash but did not get to login.

I attempted 3 times, verified md5sum signature on image file.

This morning I was successful in booting ayufan's bionic lxde first time, using same process, same hardware.

I've also tried the pinebookpro-debian-desktop-mrfixit-190905.img multiple times on 3 different microsd cards with the same results as you... I see the boot splash, briefly see the console login, and then I get a blank screen.

I ran Ayufans Android 7.1.2 build successfully from SD card this morning.
Pretty useless without a proper Google Play and Google Play Services, but it booted, loaded quick and ran well far longer than my patience. Smile

I edited the extlinux.conf on the boot partition of the microsd and changed  "root=PARTUUID=deedbeef-02" to the device holding the root partition on the microsd "root=/dev/mmcblk0p2".  After that it booted.

That makes sense. Observing the boot with the serial cable shows that it hangs at "starting kernel". The kernel cannot find init (systemd).

Looks like it's time for me to learn the embedded Linux boot process.

I'm running ayufan's bionic/mate image from the SD card without issue. I just DD'd it straight to the card, shut the machine down and rebooted with it in the slot and it booted right up to the new image.

With the mrfixit image I think I remember it hanging before login but switching to another vt and then back to the X server fixed it.
