RE: Getting Started with SABRE Lite (i.MX6)

I think your experience of upgrading u-boot is fairly normal for e14 supplied boards. The version supplied on my boards was so outdated that the Boundary instructions don't work. The Boundary versions of SL ship with newer u-boot than the e14 version, which explains a lot.

The SL is a decent enough board once you get past the e14 issues of useless demo image and outdated firmware.

On the firmware side, there's actually a different way you can boot. Rather than u-boot you can put a minimal loader into the SPI flash which then re-directs the boot process to one of the SD slots. Details here https://wiki.linaro.org/Boards/MX6QSabreLite in the "Boot from SD" section. There are advantages and disadvantages to doing this, you have to pick a single SD slot and load that version of the code into SPI, however once done you won't have to mess with sb_loader when "run upgradeu" fails - u-boot will be on the SD card and is therefore easy to fix.

One of the bigger downsides for me is that you need an SD card, I really quite like having u-boot in SPI as it enables me to load the kernel and rootfs from a sata drive without having to worry about unreliable SD cards.
