Hello - I am a bit of a newbie when it comes to Linux and modifying uBoot is something that is very new to me. I remember with the Rev B boards that you needed to hold the S2 switch in order to boot from the SD card. This was "fixed" by the time the Rev C hardware came out - I assume by patching uBoot. Anyway, the current behavior (Debian Wheezy) when there is both a valid eMMC image and valid SD image is to boot off the SD card regardless of the state of the S2 switch. I get that this is because the uBoot on the eMMC and the SD card are the same and both defaul to booting the SD card if it is there.
I'd like to get the old behavior back so that the S2 switch forces a boot from the SD card and the eMMC will ignore the SD card for the purpose of finding the boot image. The reason for this is that I am making a deeply embedded system and want to be able to update the eMMC by booting from SD card using the scripts provided (set the cmdline in uEnv.txt to make it a flasher) and I won;t have physical access to the uSD slot. Alternatively, and here is where I am a rank newbie, is there a way (script) that I can boot into the eMMC (no boot image on the SD card) and trigger a reflash of the eMMC?
