It boots on a 128GB card but looks like only has 4GB!

Moderators: chensy, FATechsupport

I know it has 8GB on board eMMC but my NanoPi NEO Air will not boot with the SD card out of it. If I plug it in a LED goes on but stays on very dim.

When I put the SD card in it boots but not sure if using the 128GB SD or it's 8GB eMMC.

Here is some commands to show what I did to see all this.

It be nice if could get it to just run off the eMMC and have the SD card as storage.

Any one set it up like that and if so how?

I guess it wants you to install java and don't want to because it has problems with hacks. So can't download it. But not sure I can't read it.
