My cross compiler tool chain version is gcc-3.4.1, glibc-2.3.2 and binutils-2.15. I have also downloaded RAMDISK from same url (http://www.git.xilinx.com). When I download zImage.initrd.elf using XMD everything goes fine, untill RAMDISK is uncompressed, I get following messages : loaded at: 00400000 008E519C board data at: 008E3120 008E319C relocated to: 00404074 004040F0 zimage at: 00404E65 00517841 initrd at: 00518000 008E2B4A avail ram: 008E6000 02000000 //there is restriction to use 32 MB of memory some of the initial messages, and then [ 0.000000] Zone PFN ranges: [ 0.000000] DMA 0 -> 8192 [ 0.000000] Normal 8192 -> 8192 [ 0.000000] Movable zone start PFN for each node [ 0.000000] early_node_map[1] active PFN ranges [ 0.000000] 0: 0 -> 8192 [ 0.000000] Built 1 zonelists in Zone order, mobility grouping on.
