Hi, I’m experiencing the same issue with last image 20200522_1559. We can rotate HDMI output to 90º in portrait, but touchscreen is still working in landscape mode 0º

#61

It may be fixed in the next version, but there is no solution yet.

#62

Hi Lili, thanks very much. For community interest, we’ve solved that using “Rotation Control” app, in apk stores and play store. As a service, rotates the screen (display and touch) about 15-20 seconds after boot, but it’s the same time that takes our own app starting for an embedded solution. Hope it helps.

Best regards

Hi. In changelog version RockPi-android9-20200304_1058 listed

How to use this hard button? Just short between pin 16 and pin 40?

#64

You need a button between 16PIN and 3.3V.
Press the button to connect 3.3V, or ground.

Hello,
I tried to make ota package from AOSP(version:20200522_1559,commit 2f865d49c2f9da2429fa0b77a34ea668d19a6ab2).
But failed. I’d like to fix it. Is there information this issue?

#66

Make sure you use stock /bootable/recovery and not the twrp /bootable/recovery currently used.
Look on Gitlab rk-vendor for the stock recovery and replace it in your SDK if you want to build ota packages.

Use this, download as tar.gz and replace.

Hi. I also wanted to do OTA package, and replaced twrp “bootable/recovery” folder to stock from this gitlab link, but make gives a lot of errors. Output uploaded here: https://pastebin.com/1Cjzjw4R

#68

You have to delete the out folder or do make installclean and try again.
Also copy the commit_id.xml from the .manifest folder to your root sdk folder and make it read-only.
If you make changes to the SDK and don’t commit the changes with git, the commit_id.xml file will be empty and cause that error.

Thanks for your help. make is done, but make otapackage is fail.

Check your power supply first. What power adapter are you using?

Hi, PPPoE Ethernet in Android 9 (login & pass) - how to enable?
ROCK Pi 4B+ (Android 9 HDMI 4K)

No PPPoE option in Ethernet settings. Only DHCP & Static.
Although in /etc/ppp/ are PPPoE files.

How do I connect to the network?
Make a patch PPPoE AOSP for TWRP.

Reset RGB 8-bit after rebooting.
Where configuration files are stored?
There used to be here: sys/class/display/HDMI/color
echo mode=1 > sys/class/display/HDMI/color

What to apply the init.d script for TUNER “COLOR” after rebooting?
