Hello,
I'm currently using the Mini-ITX board with the Zynq-7100 SoC. I followed the USB booting guide and was successfully able to boot a petalinux kernel and Linaro Ubuntu image off of USB. The problem is, whenever I try doing anything that uses the USB heavily I get a kernel panic. Here is the start up log followed by the actual error message that appears whenever I try running an image processing application:
Hit any key to stop autoboot: 4 3 2 1 0

Does anyone have any ideas why the kernel might be doing this? Thanks.
