Booting AOSP From SD Card

Hello,

Is there a method to boot the AOSP from an SD card on the HiKey960? Is there an SD image that can be used similarly to Debian? Thanks.

There’s not documented or recommended method for this. You would have to
hack the AOSP source to get the fstab correct in the DT and probably
switch to the UEFI firmware to get boot from SD (and this might
introduce a few regressions in AOSP).
