If the "ext4" is the only partition the "/uEnv.txt" is there for old boot-loaders. Basically, my goal is to stay compatible with Angstrom's 2013.06.20 release. My "images" should boot from microSD if the Angstrom 2013.06.20 release is flashed to eMMC.. Between last week's release and the July one, we had regressed on that goal. But we got those bugs worked out.. u-boot's actually searching for a few different boot files 1: microsd: Partition 1: /uEnv.txt /boot.scr /boot/boot.scr Parition 1->7 /boot/uEnv.txt 2: eMMC Partition 1: /uEnv.txt /boot.scr /boot/boot.scr Parition 1->7 /boot/uEnv.txt I've also been adding lots of debugging info to u-boot to help users hints: (here's my current wip off v2014.10-rc2, the last two debug lines before the kernel goes off should really help users..) mmc0 is current device gpio: pin 54 (gpio 54) value is 1 SD/MMC found on device 0 Checking for: /uEnv.txt ...
