RE: Unable to boot linux on Xilinx ML403 board

I am using the same image for FIFO mode. It is booting without any problem.
The problem is only coming in DMA mode. Is there any restriction on size if
it is DMA mode? Or should I tale any extra care of RAMDISK if I am in DMA
mode?

Thanks and Regards

You may be hitting the 4MB upper limit for zImages.  I had the same
problem with slightly smaller images, and it would hang at (seemingly)
random places everytime I changed something.  Making the image smaller
made the problem go away.
