Like LK, it is installed directly into the ``aboot`` +partition. Note that the U-Boot port used to be loaded as an Android boot image +through LK.

The signature +does not provide any security in this case, but it provides the firmware with +some required metadata. + +To "sign" ``u-boot.elf`` you can use e.g. `qtestsign`_:: + + $ ./qtestsign.py aboot u-boot.elf + +Then install the resulting ``u-boot-test-signed.mbn`` to the ``aboot`` partition +on your device, e.g. with ``fastboot flash aboot u-boot-test-signed.mbn``. + +U-Boot should be running after a reboot (``fastboot reboot``). + +.. _qtestsign: https://github.com/msm8916-mainline/qtestsign + +Usage +----- +Press Volume Down during boot to enter Fastboot mode. diff --git a/doc/board/qualcomm/index.rst b/doc/board/qualcomm/index.rst new file mode 100644 index 0000000..f7e0aa9 --- /dev/null +++ b/doc/board/qualcomm/index.rst @@ -0,0 +1,9 @@ +..
