Headless + serial, hangs after booting

[oneelkruns]

I'm trying to boot a micro-server Parallella board using this image:

ubuntu-14.04-headless-z7010-20150130.1.img

with a serial cable connected. The boot starts with this output:

And hangs after that. Is there no serial console? If not, how can it be enabled?

Thanks!

I'm a newer in Parallella board, met the same problem.

I tried some SD card images in both tutorial and ftp, the following image can work correctly.

ftp://ftp.parallella.org/sd_images/ubun ... 6g1.img.gz

If you want a quick start, I think it's a good choice.

Then I'm trying to generate a new image to solve this issue.
