How to Rotate screen
Tinker Board can support rotate screen 0/90/180/270 degree. Please reference for the below 2 POSTs.
set the ro.sf.hwrotation in build.prop file
$ adb connect [ip address of tinkerboard] $ adb root $ adb connect [ip address of tinkerboard] $ adb remount $ adb pull /system/build.prop .
Then, edit the pulled build.prop file with a text editor. You want to focus on this particular property:
This properties has 4 options
# other possible values: # 0 = Landscape, 90 = Portrait, 180 = reverse Landscape, 270 = Reverse Portrait ro.sf.hwrotation=90
Please note that the 180 degree needs to use the image after 20180613.
After editing, push the build.prop back to the device
$ adb push build.prop /system/build.prop
Set the persist.demo.hdmirotation property
# for 0/180 degree $ adb shell "setprop persist.demo.hdmirotation landscape" # for 90/270 degree $ adb shell "setprop persist.demo.hdmirotation portrait"
finally reboot the device.
