Just an FYI, earlier this month the team spent some time polishing and
publishing in source.android.com documentation about the flows the
bootloader goes through in Android, specially true for stock Android like
in Pixels phones or other devices based of recent AOSP versions.

Hi,
I checked with our team and the include/dt_table.h import as BSD-3 here is
fine with us. Would you like me to send a patch with just this header file
or just Signed-off-by this whole patch?
Thanks,

Hi Ramon,
What "header_version" is the boot image you have? The
include/android_image.h in U-Boot is a little bit old so it only defines
the v0 format. The "unused" field in v0 was renamed to "header_version"
where 0 means v0. The v1 adds a few more fields, including a DTB/DTBO for
*recovery* mode
Regarding the boot_android command, U-Boot supports loading Android-format
kernel images to memory and booting them. That's not the main purpose of
boot_android, it actually does that by just calling bootm.
The part that U-Boot doesn't support is all the flows around booting an
Android device that
Hi Kever,
libavb and libavb_ab are different things, and we split them for a
reason. Adding libavb is great, but you don't need to add libavb_ab as an
A/B implementation. The boot_android command referenced by Igor doesn't use
that as an A/B implementation, but uses the structs already defined in

Thanks Alex for taking the time to port this!! Some comments inline here
about your questions.

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:

Android kernel images include a header that specifies addresses and
kernel size. This patch adds a command to load these images from
storage without specifying the size or address of them, and parsing
them from the header instead.

patchset updates the Android-related headers and introduces new
commands to boot a recent Android build. This work is based on the
bootloader used in the Raspberry Pi in Android Things and extensively
tested there.

Similar to what blk_get_device_part_str() does, this patch makes
part_get_info_by_name() return the partition number in case of a match.
This is useful when the partition number is needed and not just the

in order to speed up the mmc writes on the Raspberry Pi.

When experimenting with fastboot from U-Boot on the Raspberry Pi 3 we
found that the writes to the sdcard are much more slow than when
accessing it from the userspace. These two patches speed up the write
and allow us to reliably write the sdcard from U-Boot.
