I've tried to run Emteria on the new Raspberry Pi 3 B+, but it won't boot. I cannot see any splash screen or what ever.
Is there a known issues and will be it fixed in the future?
can we expect any release the next days for the Raspberry Pi 3 B+?
There might be a new release in the next few days, but you can pretty much test it yourself by copying the device tree blob for the 3B+ from here:
To the boot partition.
Thank you for the answer. I've tried to use the firmware which you linked, but the screen hangs in the "rainbow" boot phase. Afterwards I've copied other files from https://github.com/raspberrypi/firmware/raw/master/boot/ and replaced these in BOOT. Still now working and it hangs in Kernel/Service boot. The Emteria boot screen splash will not shown.
I have to mention that I am using the official Raspberry 7" touchscreen.
That's probably a bad failsafe choice - do you have a HDMI display by any chance?
In any case, if adding the device tree didn't help I'm afraid a new release won't either. It will be some time before we have a 3B+ revision and some time to test. If it doesn't work with HDMI, the only remaining step is to connect a serial debug console.
It seems the problem is the older kernel version Emteria is using.
Is there a solution for this issue? I tried the same configuration RPI3 B+ HDMI and with Touchscreen and ran into the rainbow boot loop. It does not boot.
No, two screens at the same time are not supported for now.
