Problems with fcc_enet driver for MPC8248 (2.6.12)

Problems with fcc_enet driver for MPC8248 (2.6.12)

[Carlos Munoz]

I'm working on an embedded board that is currently running kernel 2.4.28 
without any problems. However, I am trying to upgrade from kernel 2.4.28 
to kernel 2.6.12 and I'm unable to get the fcc_enet driver to work properly.
The fcc ports are connected to ethernet phy devices. The receive and 
transmitted data out of the ethernet phy devices is all 0xff.

I tried using the fcc_enet driver from the 2.4.28 kernel on the 2.6.12 
kernel but get the same results. This leads me to believe that the core 
initialization of the MPC8248 has changed on kernel 2.6.12.

Has anyone got the  fcc ports to work properly on the 2.6.12 kernel ? If 
yes, how ? Did the MPC8248 core initialization change ?

Thanks,

Problems nfs mounting root filesystem

[Carlos Munoz]

Hi guys,

I have a problem when running off a nfs mounted root filesystem. The 
kernel mounts the root filesystem successfully. However, when fstab is 
accessed I get the following error:

   Can't find / in /etc/fstab

The fstab looks like this:

none            /tmp                    tmpfs   rw              0       0
none            /proc                   proc    defaults        0       0
none            /sys                    sysfs   defaults        0       0


I add the following line to fstab:

192.168.1.8:/tftpboot/carlos/ppc /     nfs     
rw,rsize=8192,wsize=8192,timeo=14,intr              0       0

and now I get the following error:

   mount: Mounting 192.168.1.8:/tftpboot/carlos/ppc on / failed: 
Protocol not supported

Do you know what I'm doing wrong ?

Thanks,

Hi guys,

I have a problem when running off a nfs mounted root filesystem. The 
kernel (2.6.18) mounts the root filesystem successfully. However, when
