I just tried turning on my BBB after inserting a new (presumably
therefore, empty) 32Gb microSD card into it. It failed to boot, just
sat with the power LED and the first 3 LEDs permanently on.
Taking the microSD card out makes everything return to normal, BBB
boots and I can see it on my LAN.
So should BBB support 32Gb cards and/or do I have a faulty card and/or
do I have to do something to the card to make the BBB like it?
The original "Angstrom" image does not support this out of the box.
The factory bootloader assumes the presence of a microSD card is
enough to boot from it, without any fall back. Either insert the
microSD after boot has started, add a dummy uEnv.txt telling it to
boot from eMMC in the first partition, or just switch to the debian
based image i've been pushing on this list.
Regards,
That last is a sort of Catch 22, since I can't boot from the microSD.
I just tried putting Ubuntu 13.10 (your latest version) with your
scripts onto the SD card. It all appeared to work perfectly from my
xubuntu desktop machine but inserting the microSD card into the BBB
gives the same result.
I'll persevere, I may have done something wrong on the way.
Second reply - I've just removed the microSD card and booted the
default Angstrom Linux. There is already a uEnv.txt file there which
contains the following text:-
optargs=quiet drm.debug=7
What do I need to do to this to force the system to boot from the eMMC
even if an SD card is plugged in?

Without overwriting the bootloader, I don't believe it is possible to be
certain. Overwriting the bootloader isn't that complicated, but I hesitate
to write down directions if it isn't clear to you how to figure out what
bootloader you want to use.
