DM6467 nfs error

Hi,

From the logs above, it looks like NFS server may not be configured/running correctly. Can you please check if the nfs server is running?

Also make sure that the path(mentioned as part of rootpath variable) you are providing is exported for NFS in /etc/exports file. Then stop/start the NFS service once in /etc/init.d by issuing commands like /etc/init.d/nfs stop followed by /etc/init.d/nfs start.

Thanks,

Prathap.

Before I try to flash ubl and u-boot to nand, the kernel can use the nfs (ubl in eeprom , u-boot in nand).Then my manager want me to flash ubl and u-boot to nand.I read the article

      DM6467_EVM_Installation(http://processors.wiki.ti.com/index.php/DM6467_EVM_Installation),

      I use DVSDK_2.0, I do the steps following front article. But I want to known that it can be used in my kernel.The following printing informations are use cramfs.

Feng:

I noticed this error in the logs:

ping failed; host 192.168.0.30 is not alive

What is that IP address being used for?
