Vu8M touch screen vs external power button

Post by Kraisorn »

I found the issue for the latest Android 11 (20221007) rom. If hit external power button for sleep then hit for wakeup, the Vu8M touchscreen did not respond. Please help confirm.

Did you connect a power button to the J7 header pins on the M1 board as this WiKi page?

Was it working fine with the previous Android release?

I've uploaded a trial OS image.

Try to install this OS image and let me know the result if the touch works or not.

I will release new version after replying another issue.
It will probably take several days.
