Hi all,
Android Things on rpi supports fastboot over udp since most rpis don't
expose a suitable USB port for fastboor over USB. It also uses the A/B
booting mechanism similar to Pixel phones.
The U-Boot code for the latest Android Things preview is in AOSP:
https://android.googlesource.com/platform/external/u-boot/+/android-o-mr1-iot-preview-7
In particular, the fastboot over UDP support was added by
https://android.googlesource.com/platform/external/u-boot/+/018e7c25c7c0260a6d021c84521eab808657c1a8
and subsequent commits. "git log android-o-mr1-iot-preview-7 --not v2017.07
--oneline --no-merges" should give you a cleaner list what was added on top
of 2017.07.
I believe most of those patches (or cleaned up versions) were shared in
this list at the time.
Best regards,
deymo.
