I was informed that the following is invoked by U-Boot: env import -t -r $loadaddr $filesize
I'm not sure what the flags do and have so far been unable to find documentation for them. But I believe this is acting on an environment that has been loaded in a previous command. What is the previous step to load this? In other words, where is U-Boot looking for the uEnv.txt? The Partition 2.0 document <http://elinux.org/Beagleboard:U-boot_partitioning_layout_2.0#uEnv.txt_Boot_Partition_.2FuEnv.txt> was vague (to me) on this point. Probably makes sense in some context. It isn't clear to me from this page <https://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-SetupmicroSDcard> either. It seems to imply that it will search for it on /boot of the root filesystem. My one and only bootable partition is EXT4 so it would require calling ext4load (I believe). The output is trying to do something with the MMC but never finds what it is looking for. I'm not sure which image it is trying to load. Surprised there isn't a message somewhere saying "Trying to load environment" or "Trying to load Kernel" or whatever.
