Hi -
Month ago, during 11.05 release testing, we had a case when Pandaboard
didn't boot with one particular build and one particular card, while
worked well with with other combinations.
During this test cycle, I hit similar conditions, which I however was
able to trace to the following: if at the moment of reset/boot, there's
a cable connected from Panda USB OTG (small) connector to host, it
won't boot from SD. The D2 LED will light for about a second, then both
will be off. Nothing is output on serial. As soon as you unplug cable
from the host, all boots again.
I'm not sure if this is a known condition, but guessed I'd share it.
How old's your x-loader / MLO?
I wrote a patch 97bb3ce0ca014aff9ad9f35f2b78f3976bf276f6 to solve this
back in February, it's in Gitorious x-loader repo
http://gitorious.org/x-loader/x-loader/commit/97bb3ce0ca014aff9ad9f35f2b78f3976bf276f6
If you try an updated x-loader with that in, if the mUSB port is powered
it'll just pause 2sec on start then start as normal from SD card.
