--- Quote End --- hi hippo and all, thanks for the reply, I disabled jtag uart, doing so I am not getting any prints .... So I enable it again with debug prints on jtag uart disable, also I left debug prints enable on nios serial uart. One more change I made in /Device Drivers / Block Devices / I-O scheduler / I disabled deadline io scheduler and enabled Anticipatory io scheduler ... also I disable premptable kernel support and now its booting fine with ramdisk support as given by you. I don't have much understanding with this so I can't give you any reason why its working http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/rolleyes.gif . One more thing, now I my trying to boot my ucllinux with NFS file system. So doing it ..... ************ config start ****** I have removed ramdisk path in my kernel config /Device Driver/Block devices / initramfs source file path.... Also I have enable networking support with SMC 91c111, TCP/IP support, ip from bootp and dhcp .... In Network file system I have enabled NFS file system support NFSV3 and 4 client support Allow direct I/O on NFS files and finally Root file system on NFS also Kernel automounter version 4 support is enable ********* config end ********* With this new configuration if I boot my kernel I am getting these msg with kernel crash
