the SDcard image advertised bywandboard site does not work!!

Postby logicman » Wed Mar 04, 2015 11:50 am

I have a wandboard quad. I downloaded ubuntu-wandboard-20140516.img.xz from wandboard site and extracted led to ubuntu-wandboard-20140516.img.
Then I use a 8GB SD card:

sudo dd if=/home/am/Documents/ubuntu-wandboard-20140516.img of=/dev/sdc bs=1M

I see only wandboard logo and it stops, the output by the serial port is:
