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

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

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.

 

-Rick

RE: XPS_LL_TEMAC works correctly?

[Mohammad Sadegh Sadri]

I solved the problem,=20

As i said,=20
problem was : kernel could easily mount the root file system on NFS and beg=
in init , but after that every thing stopped and there was no more progress=
.=20

My problem was with the kernel command line parameters :=20
console=3DttyUL0 console=3Dtty0 root=3D/dev/nfs.......

the second console parameter was the source of the problem, when init is ex=
ecuted, the second parameter caused no more messages to be written on the s=
creen.

I tested using both LL_TEMAC 1.00a and 1.00b , both work well.=20
thanks.
