@alvin Hey calm down a bit please.

Something like "This is an english board, could you please write in english" or even "Could you please rewrite your response in english so that everyone could understand" would be A LOT MORE appreciated than "So if you have something to say here, please post in ENGLISH !".

Hi all,

For those who can't enable OGST LCD screen and running on eMMC, here is a little guide to follow:

1. make sure to enable ogst profile in /boot/config.ini:

[generic]
; Device Tree Overlay
overlay_resize=16384
; uncomment next line to enable Odroid XU4 OGST
overlay_profile=hktft_cs_ogst
overlays="spi0 i2c0 i2c1 uart0"
 
[overlay_hktft_cs_ogst]
overlays="hktft-cs-ogst i2c0"

2. enable minitft in recalbox.conf:

system.secondminitft.enabled=1
system.secondminitft.type=overlay

3. download https://github.com/hardkernel/u-boot/releases/download/travis%2Fodroidxu3-108/u-boot-odroidxu3-108.tar.gz
4. Execute:

tar xzvf u-boot-odroidxu3-108.tar.gz
cd sd_fuse

5. overwrite sd_fusing.sh with this one:

question un peu bête à faire directement sur pc pc avec linux ou il faut avoir les deux carte sur le xu4 et faire ça a distance?

I couldn't figure out how to edit my post.
A bit stupid question to do directly on pc pc with linux or you have to have both cards on the xu4 and do it remotely?

Thanks for the warning, I did well to wait

Alors, on me prévient que ça ne marche pas. Pour l'instant, merci de ne rien faire, cela risquerait de ne plus faire booter le xu4.

@davidb2111 Write
So, I am told that it does not work. For now, please don't do anything, it might stop the xu4 from booting.

@cedric-debuiselle

Sorry for the issue. However, we have found that the emmc is shipped with an older uboot that does not support overlays.

So the trick is to upgrade emmc uboot which is located on /dev/mmcblk0boot0.

A user kindly accepted to make some tests. We were able to flash (an apparent) newer uboot over the older one and it seemed to boot, but he forget to set the switch to emmc boot and booted on sd instead. He reported to mistake few days later...

However, he's ok to send me his emmc so that I can understand how to update the emmc uboot. So stay tuned!

Hi all

I've just tested to flash 8.1 (beta) on an eMMC. After flashing with RPI Imager, I've started the XU4 with the eMMC only.
Then, I've done the regular configuration as explained here:

• https://wiki.recalbox.com/en/tutorials/video/tft/second-minitft-or-ogst-for-scraps-and-videos#odroid-game-station-turbo-ogst-xu4 (EN)
• https://wiki.recalbox.com/fr/tutorials/video/tft/second-minitft-or-ogst-for-scraps-and-videos#odroid-game-station-turbo-ogst-xu4 (FR)

and rebooted. The display was functional.

I post here the SSH commands:

mount -o remount,rw /boot
cp /boot/boot.ini.sample /boot/boot.ini
cp /boot/config.ini.sample /boot/config.ini
sed -i '/overlay_profile=hktft_cs_ogst/s/^;//' /boot/config.ini
cd
sed -i -E 's/;?(system.secondminitft.enabled)=.*/\1=1/' recalbox.conf
sed -i -E 's/;?(system.secondminitft.type)=.*/\1=overlay/' recalbox.conf 
sed -i -E 's/;?(system.secondminitft.resolution)=.*/\1=240p/' recalbox.conf
sed -i -E 's/;?(system.secondminitft.imagestretchenabled)=.*/\1=1/' recalbox.conf
sed -i -E 's/;?(system.secondminitft.imageenlargeenabled)=.*/\1=0/' recalbox.conf
sed -i -E 's/;?(system.secondminitft.imagealphaenabled)=.*/\1=1/' recalbox.conf
sed -i -E 's/;?(system.secondminitft.imageignoreaspectenabled)=.*/\1=1/' recalbox.conf
reboot

@davidb2111 AMAZING david!

Alors, on me prévient que ça ne marche pas. Pour l'instant, merci de ne rien faire, cela risquerait de ne plus faire booter le xu4.

[davidb2111]

Hello @khaneki239

Tu peux détailler, stp ?

[davidb2111]

Great news all!

We were able to make it work finally. So, when using eMMC, the XU4 boot from a "hidden" partition which is not overwritten when flashing a Recalbox image nor upgrading.
You must flash data to that partition manually.
Here are the commands to do that : https://wiki.recalbox.com/en/tutorials/video/tft/second-minitft-or-ogst-for-scraps-and-videos

Thanks to @karl0ss who sent me his eMMC and @cedric-debuiselle for testing.
