Getting into recovery with u-boot?

radiatortwo

I´m wondering if theres a possibility to get u-boot to boot into the recovery.

Normal Android devices have a bootloader that allows to select to boot into recovery or fastboot mode.

(If there is something like fastboot integrated.)

 

I´m still working on getting Android fully rooted.

And this would be really helpful.

    Well you know I'm not really an android person...  at a guess, /dev/mmcblk<n>p1 & p2 are the normal and recovery partitions, not really sure which is which though.  Probably some change to either bootargs or bootcmd in the u-boot environment can get you booted into the recovery one.

    Well I tried with uboot a few times.

    At least I´ve found out that when you try to boot to a partition that doesn´t exist, you´ll land in USB Fastboot mode.

     

    But then I remembered something and well... I´m a jackass for not thinking about that...

     

    You can boot into recovery with adb:

     

    adb reboot recovery

     

    But the recovery is pretty darn useless. It seems it´s build for a device with Hardware Buttons.

    All you see is an Open Droid with a red exclamation mark.

    On Normal devices you now would press a volume button together with the power button or similar.

    But the RIoTboard doesn´t have such built in and a USB Keyboard/Mouse doesn´t work.

     

    I´m more of a software guy. No clue what to do now...

     

    But thanks for the help.

    Given you've been able to rebuild android from source.. Is there some way you can configure the recovery partition while you're building it ?

     

    I have the LCD8000-97C, no buttons there, just touchscreen. What's the chances the recovery partition can be accessed using that?

    I´m looking through the code.

    Didn´t find anything about that till now.

     

    The display with the touchscreen would help I think if could get past this screen and into the recovery.

    But only if the recovery uses touch. Most standard recoveries only use the buttons.

     

    I know that the alternative recovery TWRP allows to use the Keyboard over OTG. (It also uses touch)

    But it doesn´t need to be activated. It just starts.

    Maybe I have to use that instead. But I can´t tell much about that right now.

    Have to find something on how to configure and compile it for the RIoTBoard.
