a question i thought i knew the answer to but, after this weekend,
suddenly not so sure. as part of a class lab, i want to get students
to boot to u-boot on a BBB after having cross-compiled and stored on
SD card nothing more than the appropriate MLO and u-boot.img files.
i could have sworn i'd done this a number of times using the
meta-beagleboard layer but, this weekend, i was messing with the
meta-ti layer and running into grief so i backed off and (predictably)
created a new SD card with nothing but those two files and booted and
... it hung repeatedly after the SPL line.
it may be something idiotic i did but, theoretically, to get to
u-boot, i need only those two files on a properly formatted SD card,
correct? the whole point is that i want students to, step-by-step,
create a fully bootable system, so that's were i want them to start.
