PineTab Blank Screen #86

Closed squierts closed 3 years ago

squierts commented 4 years ago

I'm able to flash the sd image to the PineTab, but the screen remains blank even after the reboot following a successful flash. I've tried an external monitor with no luck. The logs seemed to indicate it did fully boot. Let me know if you would like me to upload the log file.

@Icenowy ,

Hi,

Do you have a chance to check it and share the logs?

rsglobal commented 4 years ago

Hi @squierts ,

Thank you for opening this issue.

Please run the following commands as soon as PineTab boots and attach the results to this issue:

adb root
adb logcat | tee logcat.txt
adb shell dmesg | tee dmesg.txt 
adb shell lsmod | tee lsmod.txt
adb shell lshal | tee lshal.txt
adb shell lsof | tee lsof.txt

Attached are the requested logs, using the latest release, v0.5.1 dmesg.txt logcat.txt lshal.txt lsmod.txt lsof.txt

If i can help testing for the display panel, please let me know.

Thank you,

It looks like back-light driver isn't enabled.

A similar issue appeared in Postmaket OS.

Maybe this is relevant: https://gitlab.com/postmarketOS/pmaports/-/merge_requests/1627

The display of the PineTab changed short before it was shipped. That was the reason why at first the official PineTab images did not work. The backgroud light seems to switch on but the screen stays black.

Hi I will also test, I assume I have the same issue where the display is just white and sleeps after a few seconds and goes blank. Or can someone point me in the right direction ? I will hack and patch if must.

rsglobal commented 3 years ago

My pinetab is working with v0.6.1 . Discord users were reporting pinetab was working as well . There are still a lot of issues with it, we are waiting for fixes from pine64 community.

tried 6.1 on sd with my pinetab. Screen stays black here.

I just install GloDroid on PineTab as well, and can confirm that deploy-sd.img the screen stays black, but when looking at dmesg (on Host) you will see something like this:

[122104.161085] usb 1-1.2: New USB device found, idVendor=18d1, idProduct=4ee0, bcdDevice= 2.15
[122104.161092] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[122104.161095] usb 1-1.2: Product: USB download gadget

[122104.161100] usb 1-1.2: SerialNumber: 92c0eababc8699d8

at this moment you can start the flash-sd.sh script. Of course sd can be substituted with emmc
