[ODROID XU] Only boots with UART connected.

Postby KenjiTakahashi » Sat Mar 29, 2014 10:18 pm

Hi all,

So I finally got my XU (Lite) today and problems already.

Since the subject spoiled the surprise anyway, I'm going straight for the facts.

Without UART cable: RED+GREEN=>RED+BLUE=>RED only. Fan spinning full speed. Nothing happens later. Not after a minute, not after five or ten.
With UART cable: Everything goes fine and smooth.

eMMC/microSD all the same. No such problem with "stock" Android (if I can trust the LEDs/fan, no display to connect to ATM ;-)). Nothing else connected anywhere (besides PSU, of course).

Any clues :-)?

Okey, so I've done some "redneck style" cable plugging to get some logs. Everything is perfectly normal, then the board suddenly stops at
$this->bbcode_second_pass_code('', '
^@^@^@^@^@^@^@[ 5.645629] EXT4-fs (mmcblk0p2): couldn't mount as ext3 due to feature incompatibilities
')
and seems to do nothing from then on... This line is perfectly normal as well.
I wonder if the garbage at the beginning might have sth to do (with UART connected there's no garbage)?

#Update 2: Just tried Fedora 19, works fine. Looks more and more like ALARM specific problem, duh. Anyone?
