Official 7" Touchscreen

IKS

I'm sorry to hear that. By now we have fixed all issues causing the bootloop known to us. Without an error log it will be difficult to find the problem. If you can, please setup a serial connection and read the system log during the boot: https://elinux.org/RPi_Serial_Connection

That's quite the same for me.
New SD Card, 64Go Class 10, Official Touchscreen 7''. Works fine with Raspbian and OSMC.

I just download the installer, format my card, make the installation. Some few lines appears at the init, and the word EMTERIA whith a "-" flashing and the screen turn white and progressivly black and that's all.
(15 minutes)
I turn it off and replug the power cable : This time "EMTERIA-" stay, but nothing else.

Last version : 0.4.5

Any idea?

(i don't have RS232 cord to capture boot logs)

I'm afraid we can't fix it without a log. Could you please try to mount your sdcard in linux and check if there are any logs in /userdata/cache/logs? The folder can be empty though, if the system crashes too early.

We will check if we can redirect the boot log to the screen in the next version. Maybe you can capture them by recording a video.

Hope you can find the mistake!

I've already purchased an TTL adapter, but it will still take some weeks to delivery^^

Great, thank you! Stefan has found the problem: it is caused by our recent graphics updates, which seem incompatible with the driver for the official touchscreen. He is already working on the solution and we hope we can fix it ASAP.

InfecteD

That's cool!
I'll wait for your message and test it immediatly!

Unfortunately the problem can't be fixed with the current RPi firmware. We'll likely be reverting back to 0.4.4 with BGRA graphics.

Is there a way to download older versions?

Hi @InfecteD,
you can choose older versions in windows.

InfecteD

Hi @InfecteD,

its here:
#139

"Are you running the installer on Windows? Old images are saved in C:\Users[Username]\ AppData\ Local\ Emteria\Installer"

InfecteD

Ok, i know that.
But i just place interest in Emteria few days ago... So i've juste rpi3-v0.4.5 and a cache folder...
There's no way to download it directly from a mirror?

How do I downgrade to 0.4.4 from a Mac?

obero

It recognizes the original screen but its quality is very poor. Smaller fonts are almost unreadable and background moare. You can not set the resolution or the sound. The sound is just a sharp, continuous beep.

IKS

@obero, which version are you using? All these problems were fixed in 0.4.4. We had introduced further graphics improvements in 0.4.5, but they are not compatible to the current touchscreen driver, so we reverted them in 0.4.6. The picture quality is just fine on my device.

InfecteD

Ok, its work for me!
Thanks
