I am using u-boot on the Avnet V5FX30T (Xilinx FPGA, PPC440) eval board to boot a Linux 2.6.27-rc4 kernel. I can use u-boot to tftp the kernel, ramdisk, and device tree blob to RAM and boot from there OK. I copied the kernel, ramdisk and blob to flash and verified those elements were programmed in flash correctly with 'iminfo', but when I try to boot from flash the boot process hangs at "Loading Ramdisk to 03d59000, end 03ec8f20 ... OK". At this point u-boot will restart (after a WDT-induced reset?) after a few minutes. Interestingly enough, I can boot from flash IF the ramdisk is already in RAM with a "bootm $(kernel_flash_addr) $(ramdisk_ram_addr) $(blob_flash_addr)". This leads me to believe something is going wrong in the copying of the ramdisk from flash to RAM. Perhaps I am doing something wrong or missed a step somewhere? I have read the FAQ, but have not found anything relevant. Perhaps someone here has had this problem too and can offer a solution? Any help is appreciated. Many thanks in advance!
