VIM3 with Ubuntu bionic + Touch screen TS050

[Gytis]

I have built Ubuntu bionic using fenix script. Now trying to add touch screen TS050 but it is not detected nor displays anything - can you help me figure out what’s wrong?

Hello @Gytis

Please edit /boot/env.txt to enable the screen.

[Gytis]

Added:

mipi_lcd_enabled=true

to /boot/env.txt but still the same

I’ve also yet to get the TS050 working with edge V. I can’t find any find any videos or images anywhere online that show this running either. If I edit /boot/env.txt the touchscreen turns on but it just hangs on the boot logo.

Hello @Gytis @blueberryberret

I just checked Edge_Ubuntu-server-bionic_Linux-4.4_arm64_EMMC_V20190116 on Captain. If you don’t edit /boot/env.txt file, you can at least see the Khadas logo for a while on screen, and then disappeared. If you set mipi_lcd_enabled=true and you will see the full booting log output to the screen.

@numbqq, can you try with VIM3? And please also share how you plug it in - I think I do it properly but just to verify as there is no manual available.

I am trying to use TS050 with VIM3 Pro, but screen is not showing anything. HDMI output works as usual.

Thanks @numbqq, I’ll try this over the weekend.

Hello @Gytis

LCD driver seems broken in current source code, I will fix this…

By the way, if you want to use the LCD, you have to unplug the HDMI cable, or the LCD will not work.

[Gytis]

Please post here when fix is available

Is it so that two monitors cannot be used at the same time? From website I understood that was possible…

Dual Independent Displays
HDMI and MIPI-DSI

Current stage not, in the future, YES. Need more software support.

Any idea when that could be done?

I think I am going to use VIM3 as Ubuntu-powered home media server then with status displayed on Touch screen and VIM1 with Android plugged to TV as music and video player Kodi on VIM3 + Ubuntu 18 looked bit sloppy - controls tend to slow down from time to time

Tried VIM3_Ubuntu-xfce-bionic_Linux-4.9_arm64_EMMC_V20190830 - touch screen works! But only when HDMI is not plugged.

Can you include changes to fenix build script? I’ll try to build ubuntu Bionic from source again.

@Gytis

Yes, it is. We will resolve this issue in future release.

Already pushed to the github. You can use the latest repo to build.

I still can’t get this working with the Edge-V, I’ve tried the new V20190830 lxde and server ROMs. Can boot initially using HDMI, edit the env.txt to “mipi_lcd_enabled=true”, sync and sudo reboot. Afterwards I still get the khadas logo on boot for the TS050 but nothing else happens and when I try with a HDMI connection it only displays a white screen.

@blueberryberret hello.We do a test with it and we found the reason.This is a bug about dtb, which we will solve in the next release. I’ll tell you again then.

Hello @blueberryberret

I have updated the kernel to fix this issue.

Please reflash the image and update the kernel.

khadas@Khadas:~$ sudo apt-get update
khadas@Khadas:~$ sudo apt-get upgrade
khadas@Khadas:~$ sudo vim /boot/env.txt     # Edit to enable LCD
khadas@Khadas:~$ sync
khadas@Khadas:~$ sudo reboot

[Gytis]

Just to add, Tone Board is recognized as audio device and works fine with Ubuntu Bionic Xfce

[blueberryberret]

I very much appreciate the quick turnaround on updating the kernel and addressing my problem:slightly_smiling_face: I can now boot ubuntu using the TS050 lcd, the only problem is that it is not recognizing touch input. Touch works when I boot android and I have tried it with the latest xfce, lxde and mate images, built using fenix as well as the ones provided on the khadas site. Touch is recognized using a hdmi capacitive screen but not with the TS050. Thanks again for the help so far!
