it looked like you enabled both serial uart and jtag uart.

please try enable only one of them, eg jtag uart, and with console support.

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&#39;t have much understanding with this so I can&#39;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
