This was working for last couple of months, suddenly it starts giving this problem consistently. When creating zImgae, I followed the guideline but changed the target from versatile to realview-pbx-a9. Browse other questions tagged boot nfs pxe or ask your own question.

i am not sure what this error code means. Configuring the network You need to configure a network interface so that you can communicate with the emulated target just as if it was a real board.

can u pls find the solution for this ASAP. Nfsroot You will have to make one small change because the Digi CCW9 target board we use for training has the serial console device as ttyS1 whereas on the Versatile it is Try appending the options "-net nic,model=ne2k_pci -net user" or "-net nic,model=pcnet -net user" or "-net nic,model=rtl8139 -net user" to QEMU command line. - is the directory really exported? For things to work properly, the /etc/exports should contain instead: /srv/nfs 127.0.0.1(rw,sync,no_subtree_check,no_root_squash,insecure) The no_root_squash option is needed to access these files as root from the NFS client.
Not all devices are supported on all targets. Thinking about it a bit more, I realise that the situation is general and common enough to be useful to many people (or so I hope) and so I have written Cannot Open Root Device Nfs Or Unknown-block(0 0) I forgot to mount /dev as ramfs as you described, resulting failure while executing mdev command.

It turned out that there is not support for nfs server v2 in kernel 3.15.6. Should I report it? I don't think root, nsfroot, ip and rinit options are the problem because the kernel is not giving you any messages from the beginning; although I don't understand rdinit without providing I updated the tcpdump above with information from the new test if you're willing to take a look. –johnmadrak Aug 23 '14 at 6:37 | show 2 more comments 1 Answer

Optionally, for PCI cards, you can specify the number v of MSI-X vectors that the card should have; this option currently only affects virtio cards; set v = 0 to disable The NIC is an e1000 by default on the PC target. Any clue,why is it so? Balau 2013/03/27 Maybe your cross-compiler has a libc that is tied to a newer kernel version and is incompatible with older kernels. Does Intel sell CPUs in ribbons?
one of these 2 actions probably fixed the problem. nfsd: request from insecure port (127.0.0.1:37844)! Balau 2010/05/12 Yes, it happens to me also: the message is written because 37844 > 1024. You can get the initrd.img after downloading the Base rootfs by using the command yum groupinstall base. You can also run QEMU with its -s option and then connecting with arm gdb to port 1234 and vmlinux as debugging file to check where the execution stopped. Raz
