Output to the LCD does not work A20-olinuxino-focal-minimal-20210513-112230

[ivanbraga]

After some time I returned to a project that is using an A20-Som204-EVB.

Following the guidelines of this link "https://olimex.wordpress.com/2020/04/21/olimage-mainline-linux-images-building-script-for-all-of-our-olinuxino-and-som-boards/ ".

I downloaded all the images and tried to make the LCD output work, but none of them ran on the LCD.

My LCD is this "lcd-olinuxino-10ts" template from this link "https://www.olimex.com/products/olinuxino/lcd/lcd-olinuxino-10ts/open-source-hardware".

I followed the guidelines of this link, "https://www.olimex.com/wiki/armbianhowto":

- olinuxino monitor set lcd-olinuxino-10
- SaveEnv
- Reset

And also, for Bootlog on HDMI / LCD Console:
  - Console = Both

I will not use HDMI, just the LCD.

I am already tried to make it work with these images, even tried to build a new image, following the guidelines on page 13 of the PDF "Olimageguide - Linux for Olimex Allwinner Boards.

But I get this error.

Exception: Command Failed: qemu-debootstrap --arch = armhf --components = main, universe, focal / olimage / output / a20-olinuxino / filesystem / focal-minimal http://ports.ubuntu.com/

E: Command Failed: qemu-debootstrap --arch = armhf --components = main, universe, focal / olimage / output / a20-olinuxino / filesystem / focal-minimal http://ports.ubuntu.com/.

For the record. In this image works.

Linux Oolinuxino 5.2.21-Sunxi # 5.92.4 SMP Thu Dec 12 08:46:22 EET 2019 Armv7l Armv7L Armv7l GNU / Linux

Any orientation of how the LCD works is welcome.

Generally to change video output in Olimage you need to run olinuxino-display script. However, it is made for Olimex-made displays.

Check this document: https://github.com/OLIMEX/OLINUXINO/blob/master/DOCUMENTS/OLIMAGE/Olimage-guide.pdf

Hi,

'olinuxino-display' script is not in your last image.
How to switch output?

[LubOlimex]

Where do you look for the last image? Is it here:

https://images.olimex.com/release/

[kolevs]

Sorry,

I found script in /usr/sbin

Thanks
