Console Kit - Any way to make screen work?

[zurkeyon@gmail.com]

Hello,

I have a console kit I bought a year or two ago and never got around to loading up.

Recently, I have been trying to tinker with it and my XU4 and I am finding that no matter what image I use (Bacotera, Emuelec, OGST, Recalbox) I am unable to find any current info to make the screen work.

The repos to install the screen on OGST do not seem to function anymore, and I am unable to update / upgrade. The connections do not seem to go through and it just errors out.

I have been trying to get the screen working for several days now to no avail.

The screen clearly works, as my USB front ports are working and the backlight is coming on. But no video/gifs/images show on the screen, regardless of OS/Method to activate the screen.

I have read about a kernel issue causing the screen to not work after a certain kerner version... Is that right?

Does this screen still have a path to usability?
Or is the console kit EoL?

All Kernel based on the default Kernel from HardKernel 3.10, 4.14 and 5.4 should work.

Kernel 3.10:

Code: Select all

modprobe spi_s3c64xx force32b=1
modprobe fbtft_device name=hktft9340 busnum=1 rotate=270

Kernel 4.14:

Code: Select all

modprobe spi_s3c64xx force32b=1
modprobe fbtft_device name=hktft9340 busnum=1 rotate=270 force32b=1

Kernel 5.4:
There is a device-tree-overlay that is called ogst which you have to activate.

While the OGST image still works and the repository can easily be fixed, the image itself is outdated and probably shouldn't be use anymore.

Using the display itself in a gaming image is up to the developers of that image.

Understood.

I'll take another shot at it and see what I can make work!

Thank you for the info!

Sorry, one last quick question on this...
As one is getting this set up, what is the best testing method to see if you have it working correctly?

Thanks again!

The first sign should be that the backlight of the screen should go on, which kinda shows that it has power.

For testing you can download https://oph.mdrjr.net/meveric/other/pic ... 20x240.raw

Depending on if you have HDMI connected or not you should have either /dev/fb1 (if you have HDMI connected) or /dev/fb0 (without HDMI).

You can then push the picture directly to the framebuffer device like this:

Code: Select all

cat splash_320x240.raw > /dev/fb0

and you should see the picture on the screen
