Boot problems

[djhnsn]

The more I know, the less I know (yes, I know, I should get serial)
@djhnsn ,, maybe a clash between uboot minimal dtb and kernel dtb,,  just a guess
manjaro has a bsp uboot, based on mrfixit, maybe try that
If there is a uboot on emmc, that is supposed to be the 1st found,, and the only one used
The way to be sure,, save 1st 16M, & mbr (on SD OR emmc), blank 1st 16M, restore mbr
So that there is ONLY 1 uboot, see what happens
To boot emmc (if that is what has blank uboot), a small card with ONLY uboot on it
If you get 'NO LED', remove 'bad' uboot, do long press dance (with 'good' uboot inserted)

I have tried the bsp uboot, and it exhibits the same symptoms. It seems like pretty much exactly the same thing.
