I am confused of installing CoreELEC 19.4. on Vim3L eMMC. I found zipped image of CoreELEC 9.2.5 for Vim3L, I uploaded it to Vim3L by USB cable, it was autoupdated to 9.2.8, it works fine.
I tried to install CoreELEC 19.4 by uploading update to .update directory, I was unable to boot. I prepared fresh install on SD card, it works. But I would like to use eMMC, I prefer better performance. Is there any image or guide how can I do it?
I tried to use ceemmc, there is no SD card and here is output
