Are you running this script from an external SD/MMC card? I assume so, 
Do you have a log? Did you run this script unmodified?

It seems the processor was able to load MLO, which in turn loads u-boot 
SPL, but where from? Is your external MMC still in at that stage?
If not, then at least up to there, stuff have been loaded from your eMMC 
VFAT boot partition.

One (e)MMC instance for u-boot SPL (while "full" u-boot sees 2, see 
below)...

I'm not sure if it's the beginning of your problems, but it seems u-boot 
SPL is having some trouble with (e)MMC ...

... but anyway, u-boot SPL was able to load and run a "full" u-boot, 
again, is it from eMMC? If so, this is looking good.

2 (e)MMC instances for "full" u-boot (u-boot SPL had only one), looks 
good to me so far.

If you don't have a uEnv.txt on your boot partition, then this message 
can be ignored, if you have one, it means that u-boot couldn't read it

The eMMC isn't detected, or maybe it's your empty external MMC slot, or 
both, can't tell, I'm not familiar with this :(

And the BB black doesn't have NAND!

Did you have a look at u-boot and u-boot SPL source code, especially the 
(e)MMC stuff?

My half-a-cent.
