Hello, is the OGST screen (N64 case for Odroid) supported?

J'ai testé rapidement avec cette image 4.14.
Nickel pour l'overlay.
En revanche il y a un souci d'affichage (couleurs) sur l'écran TFT en forçant le module spi en 32bits. Sans forcer, les couleurs sont ok mais ça lague à mort.
Voici le code simplifié pour info:

# unload then reload spi module forced to 32bits
[ `/sbin/lsmod | grep -c spi_s3c64xx` -ge 1 ] && rmmod spi_s3c64xx
modprobe spi_s3c64xx force32b=1

# load TFT screen module
modprobe fbtft_device name=hktft9340 busnum=1 rotate=270

# draw
ffmpeg -re -i logo_file.mp4 -c:v rawvideo -pix_fmt rgb565le -f fbdev /dev/fb1

Probablement un soucis driver/kernel.

Pas de problème de ce coté là avec le vieux kernel legacy.

Edit : même soucis sous Ubuntu 18.04, kernel 4.14

Well, finally made it works on the 414 image 🙂

So, I made a specific installation package.
Need the 414 image version (4.14 kernel) : https://batocera-linux.xorhub.com/forum/d/1481-ogst-screen-support/17
Then get ssh connexion : https://batocera-linux.xorhub.com/wiki/doku.php?id=en:access_the_batocera_via_ssh
and run following command line:

wget https://www.dropbox.com/s/b8s35z0p33al8e9/install.sh && chmod +x install.sh && ./install.sh

It will download and install all the necessary files and reboot.

Refer to the recalbox wiki for details if you need : https://github.com/recalbox/recalbox-os/wiki/Odroid-XU4-tft-screen-OGST

The whole stuff available here: https://www.dropbox.com/sh/xxhxhv59i9l8odq/AABoFIX2PVJxzf41aaflsSC9a?dl=0

littlebalup super boulot je n'aurais pas le temps ce soir d'essayer ça mais tu déchire !
La prochaine étape c'est quoi ? La team doit mettre la modif en prod sur la prochaine release j'imagine..
j'aurais bien aimé voir une petite demo en vidéo pour le coup mdr

nadenislamarre

littlebalup i'm reviewing your package. on batocera, do you really need to override the current ffmeg ?

nadenislamarre

yes. i must see to integrate it.

guyomemalik

nadenislamarre hope maybe for the 5.22 ;-) haha

jimmythesnitch

I can Verify this works.. just tried it out with the 414 image fresh install, then installed to my external usb 3.0HD, copied some SNES and n64 games over, rebooted, then SSH'ed in and ran the above command, it rebooted.. and i have the batocera logo on the TFT, n64 logo works, as well as gameboy, and snes, that's what I've tried so far.

On recalbox there was an issue, with the old built in version, for some video to loop correctly (I'll give you the link once recalbox forum will go back from death...)
I didn't tryed the version from batocera... I only did the same thing than on recalbox...

That was the ffmpeg issue: https://trac.ffmpeg.org/ticket/6139

Is it possible to adapt it on new 5.22?
By copy & paste a folder or files?
Or run a script ?

Jack_n

Hello,
i did like the OGST screen support very much.
When i try to install the script (wget https://www.dropbox.com/s/b8s35z0p33al8e9/install.sh && chmod +x install.sh && ./install.sh) on V5.21 i only get a black screen after restarting the odroid.

Without using the install script i get an Image of Batocera on the OGST screen, but it never changes.

Did you stop supporting the OGST ?

Best Regards
Joachim

jimmythesnitch

Jack_n you need to use the image in the above post, 414 kernel, it won't work with 5.21.

Jack_n

Thank's a lot.
I asked because in the 5.21 Version i had more Emulators working than in the Release with 414 kernel.

OGST screen support would be super great. batocera is the best retro gaming image for the xu4 but using it with the case seems like a waste atm.

nadenislamarre

5.23 includes a new feature to call script properly when you start/stop a game.
it should be included in 5.23 while it is easier.

flaker38

nadenislamarre Good news !

shs2002

nadenislamarre In version 5.23 of batocera, can xu4 support ogst function?
I like batocera but I am using recalbox because of ogst.
In the next version I hope to hear good news.
Thank you for your dedication.

nadenislamarre

now that there are the scripts, if somebody updates files, it is possible
