Hi, did you figure out a solution yet? I am facing the exact same issue

[jonsmirl]

The Android source is set up to use the flash. You are booting from SD card and don't have a flash module. I tried screwing around with the source to adjust it to work from only SD card. I gave up after a while and bought a flash module.

It is unable to mount things because it is trying to mount them from the flash device.

Hi,

What is the way to compile ? I tried 'source build.sh' but Build uboot failed ? Am I missing some tools ?

Thanks

I don't have an EMMC Module and don't wish to buy one as I am using Rock64 in one of my products and EMMC Module is costlier as compared to SD Cards.

It would be better if Pine64 provides a patch file to fix things. They have released Android Oreo 8.1.0 Image for SD Boot so they should have the working source code with them.

Probably. Posting the error logs on del.dog and sending the link here would allow me to help you
