问题
I just borrowed cubieboard2 from my friend and tried to boot it up. I connected power to 2A USB charger, hdmi to my display and keyboard to USB. Red (Power) light turned on.
Whithout SD card system boots from NAND, kernel messages shows up, but hangs on
[ 17.000000] Mali display drivers loaded (SOMETHING LIKE THAT)
Nothing more is happening, but system is responding, because when I insert SD card it shows propper mesage:
[ 800.000000] sd card info...
The default system on NAND should be android (my friend didnt touch it), but I'm not able to get anything more then kernel log
With lubuntu SD card system boots up properly, but the first image I get is desktop. After power on - screen turns on, but is whole black, no messages at all. After about 3 minutes desktop shows up.
With default cubieboard2 busybox created exactly as on http://www.smida.it/geekeries/cubieboard-buildroot.php - this is the most frustrating part! It took about 5 hours to make image using virtual gentoo machine on my pc. After that i created SD card with my OS. When I inserted SD card and booted device - screen turns on, there is some SD card activity, but no image at all. Screen is black (but turned on), SD activity LED blinks for a moment and then... nothing. Num-lock responds, pressing random keys - no SD card activity, but alt-ctr-del gives board a restart.
- How can I make my board working?
- Is there any way to 'debug' it? By connecting serial interface or something like that?
- Can I 'emulate' image on my gentoo virtual machine using qemu?
- Maybe there is obvious mistake I'm doing?

Ok, finally got solution.
In fact my board was booting and everything was fine. But in inittab the only tty was ttyS0 which was serial tty.
After adding getty with /dev/tty1 everything works fine.
