Hi, Just wondering - is it possible to use U-Boot on the Xilinx XUPV2PRO board or any similar tools (such as libfdt?) to copy a Linux kernel and ramdisk filesystem from a SystemACE card to memory, uncompress them and boot the Linux kernel etc?? If so is there any notes/docs about how to do this or similar online anywhere? Any info. appreciated, Regards&Thanks, Alan. _______________________________________________ Linuxppc-embedded mailing list [email protected] https://ozlabs.org/mailman/listinfo/linuxppc-embedded
