bout the error between tablet and external penal(celadon android O)
by MR. Children
I have a tablet with a touch penal and hdmi external output.
When I only use the touch panel, everything is fine
But
But when I plug in the external hdmi panel, the hdmi panel can't be displayed,
and the touch function will be wrong (do not match the touch panel)
I think the error is in android.hardware.graphics.composer
This error did not occur in android x86 oreo (Not imported android.hardware.graphics.composer)
My touch panel information
Resolution: 800x1280
Interface type: mipi
Touch type: capacitor

RTC Standby / Wakeup + Forced display resolution
by Dominik Louven
Hello everybody,
I’m facing 2 tasks right now and I am not sure how to proceed.
1. ) I would like to put my celadon device into standby / deep sleep with an scheduled RTC wakeup, it seems like I can use ‘ /sys/power/state ' by writing “freeze” into it.
However I am unable to schedule a RTC wakeup, I tried doing it by writing the wakeup time as unix timestamp into ‘ /sys/class/rtc/rtc0/wakealarm ‘ but nothing seems to happen when the desired time is reached. I have to physically turn on the device again.
1. ) I would like to override the default resolution with a different one, is there a ‘good’ way to do that ? I know that some android projects support changing the resolution via properties but how can I archive something like this in celadon ?
Thanks in advance and best regards,
Dominik Louven

How do I get root access in the terminal emulator
by Soham Sinha
Hello,
I installed a Celdaon build based on Android 8.1 It is installed on an UP2
board. I enabled the terminal emulator by turning on the developer options.
But the terminal emulator cannot do almost anything. I want to get root
access on this emulator. But I cannot even do "ls" at any place. How to get
the root access on the terminal emulator?
