Can't boot up Manjaro 20.04 eMMc image from SD card...

[User 6582]

Thanks for the suggestion, but it doesn't seem to work. Very odd. 
I'm sure there must be something I'm missing..

This is one of the first hundred  PBP. Wondering if there's something different about this one that is causing an issue?

There has been at least one reported instance where the user couldn't get past the splash screen for ~20-30m. During that time ESC did nothing or cancelled the installer running in the background. After that time elapsed, hitting ESC allowed them to complete installation.

Which eMMC installer are you using, for KDE or XFCE? You might try using the other one.

If you can boot Manjaro from SD without an issue, you could use that same .img and write it directly to the eMMC, also.

There shouldn't be any major differences in the older/newer PBPs, aside from some cosmetics, like the strength/brittleness of the plastics. I have a PBP from the first and second public batches, and neither shows any difference in how they run OSes.

Thanks for that info Top!!
KDE....I like Manjaro for many computer uses. So if KDE works, it'll be a big boost for me.
 I'm going to work on my patience and let it take its time.
Will report back later...Many Thanks again!! :-)
