Zedboard Linux Boot hangs at "mousedev: PS/2 mouse device common for all mice"

Hi

In my experience boot problems are generally caused by a problem with the device tree.  As a starting point, you probably won't have the device driver for the OLED screen in your kernel, so you should remove this from the device tree.  If you need help with modifying your device tree I'd suggest reading the tutorial below:

http://xillybus.com/tutorials/device-tree-zynq-1

Matthew

Thank you very much for your quick reply,

I have removed the OLED screen in the device tree and the problem still exists...Yet when I tried to replace my compiled zimage to the zimage that I got online at
http://zedboard.org/sites/default/files/design/zedboard_refdoc_Vivado_2014-2.zip
I was able to boot...Therefore I was wondering if it is the problem of the kernel source code or it is because of the problem that the device tree and the zimage doesn't play well with each other.
I wish I could use the zimage downloaded directly but I could not because I need other drivers as well.
I sincerely hope that you could give me some insights on solving this problem....I am really fustrated :(
Below is the message log after replacing the zimage.

Hi

I have previously used the Digilent kernel without any problems, so I doubt it's a problem with the source.  I'd suggest removing everything in your device tree except the essential components and add things back until it stops working again.

It looks like your first log fails when the second one reaches "i2c /dev entries driver".  Possibly a good idea to search the device tree for an i2c component and remove that.

For reference I have a basic one which should work:
