Hi ADI,

 

zedboard, linaro 2012.09, adv7511 HDL reference design, linaro X-window crash

 

I am working on adv7511 HDL reference design on zedboard, with HDMI outputs a linaro X-window desktop on a 1920x1080 monitor. However, the linaro desktop tends to crash. Looks exactly like a log-out, and I have to input the password to login again.

 

I doubt whether limited DDR resource crashes the OS, since zedboard only has 512MB DDR, comparing to 1GB of zc702. Also notice Linaro does not have a swap directory.

 

Below is partial result of the " top " command in linaro terminal

Please advise, thanks in advance.
