There are a couple of bugs in the v1.00b version of xps_ll_temac (one in checksum offload, one in multicast address reception).  You should try dropping back to v1.00a of the core and give that a try, or if you have EDK 10.1 you can move to v1.01a of the core.

Rami,

Thanks for reply,

But if u study the kernel log I posted carefully, you can simply see that Kernel has mounted the root file system, 
Look at this line in my prev post : VFS: Mounted root (nfs filesystem). then init has began and after that nothing more happens. 

the NFS is working correctly and the folder can be mounted easily from other computers. I personally think that the problem can be with NFS or the root file system of ELDK. 

I have done the same things with older versions of EDK using PLB_TEMAC and every thing has worked correctly.

Hi,

 

I would suggest that you verify that your system file is already mounted on the host PC (where your server NFS is installed), and that the /etc/exports file (configuration file of the nfs server) permit to your board to mount the system file.

 

example of an /etc/exports file:

 

/opt/ml403/rootfs

192.168.206.223/24(rw,no_root_squash,sync,subtree_check)

 

where the ip addresse is that of nfs client, and the path indicates where I mounted the system file.

 

Good luck,

 

Rami

Objet : XPS_LL_TEMAC works correctly?

Hi all,

Using: 
EDK 9.2.02, 
Xilinx Linux 2.6.24-rc8-xlnx
XPS_LL_TEMAC version 1.00.b

I bring up the Linux kernel on ML403 -Rev04 board,
LL_TEMAC buffer size 128kbits, and set to use SG DMA

I encounter the following messages when the kernel wants to mount the root file system, as one can see the kernel has mounter the nfs root file system and init is initiated, but after that a Link carrier lost happens and it stops working. 

is this behavior natural? ( the PC has attansic gigabit ethernet port with kernel 2.6.24.4 running, nfs works very well in other tests)

thanks
