The "standard" images create a 4GB Linux partition (the size of the
eMMC should one use the image to flash the eMMC). To use the rest of an SD
card requires playing games with the partition table (somewhat scary to
"delete" the only partition on the card, before writing a new definition
using the whole card, without losing the data itself). I don't think the
current images create a FAT partition at all.
So... How you managed to get a nearly 7GB Linux partition implies using
a "non-standard" OS image. What are the contents of the FAT partition? It's
potentially a case that the boot sequence is looking for u-Boot
initialization on that partition.
Oh, BTW, I haven't had to use the "boot switch" since last year. Insert
SD card and restart device... Boots OS from SD card (might still be reading
u-Boot info from the eMMC but then transfers over... I admit I'm not
skilled enough with boot systems to know for sure)

If the card isn't booting off the SD card, you might have to examine
that uEnv.txt file for things that may be erroneous, since (as I understand
things) it defines some of the stuff used by u-Boot to get to the rest of
the OS.
