Wrong command - read what I requested.

But I think there is something wrong with A/B system

[   11.903601@0]  /dev/mapper/dynpart-system_b: Can't open blockdev

Please enable terminal sharing because this will be much, much easier and quicker.

24

Sorry, I’m not at home right now. I have time from 8:00 to 9:00 p.m. I will open the sharing service and contact you then. Would you mind? Thank you coreelec team.

25

Do also command

fw_printenv | paste
26

I’ve already turned on remote

27

I don’t see anything in my dashboard. Did you set Send invitation code to CoreELEC developers ?

28

I have enabled remote, just restarted, because I can not log in ssh, now you can try, thank you.

Nope, doesn’t work for some reason. Maybe connection is blocked from China.

Please test this image: 198.91 MB file on MEGA

After boot run this 2 commands and send links.

journalctl -l | paste
dmesg | paste

Hello, no one can’t find the super section, thank you.

Try this and again run both commands. One issue is solved, hope the second one will be also now.

Sorry, made a typo in script. Use this image and again run both commands.

Sorry, no need to test this !!!

40

I have no problem using the second image now, right?

41

Playback should work but not DV. This image should fix that. Again run both commands.

Media playback should be fine now because TEE stuff succeed.

But there is no DV because the kernel module from Android is not compatible with our linux kernel (kernel on Android is too old - 5.4.61 and we are using 5.4.210).

Hello, why I opened the device on 1080p to run coreelec flower screen phenomenon, may I ask whether this can be solved!

45

What is your TV? Can you try different one?

46

Toshiba’s small TV 1080p, the other is I tested earlier, Toshiba 4k TV, yes, 1080p TV flower screen is normal phenomenon, right? Thank you coreelec team. I hope 1080p does not spend the screen is the best, by the way, I plan to contact the other side to let them upgrade the kernel version, to achieve compatibility, thank you.

Hello, @vpeter ,I have contacted the after-sales customer service feedback, the customer service has feedbacks my needs to the technical department to deal with, so that they upgrade the kernel to 5.4.210, I update to the latest version, contact you, turn on the dv, thank you again coreelec team, happy test.
