NFS issue with ETH0 on PowerQuicc MPC8248 Processor Board

gsatish10 · ‎11-22-2016

MPC8248 Processor related board supports 10/100MB T Full duplex with kernel 3.10

ETH1 is working fine for Kernel 3.10 to mount NFS , with same configuration ETH0 is not working.

Data sheet is saying both ETH0 & ETH1supports 10/100MB .

But it is stopping with following messages on one of custom board using MPC8248 Processor

IP-Config: Complete:
     device=eth0, hwaddr=00:10:ec:00:5c:5b, ipaddr=10.162.103.194, mask=255.255.0.0, gw=10.162.0.1

It is hang here.

Please support me and thanks in advance

Is there u-boot on your board?

Could you test your board using a standalone project?

Attached file contains simple standalone project for FCC1 and FCC2. It is CodeWarrior project for the MPC8272.

Have a great day,

Hi Pavel,

Once I get into Shell Propmt through Intial Ram disk Image.I can mount the file system through ETH0 ,

But when I am trying NFS mount, It is getting the Issue as

NFS server xxxxxxx not responding, still trying

I saw issue is becuse of Port Mismatch and nolock option added to Mount command.

"mount -o port=2049,nolock <host ip>:/<mnt file path form host> /<mnt path in target> "

using the above cmd, Mounting is done successfully with slight delay to mount, using ETH0.

But when I try yo add the same arguments to kernel command line , it is showing same error.

I think this is related to Rx Packet loss Issue too.

Once entered through Intial RAM DISK , assigned the IPs to two ETH ports and getting the problem as RX Packet Loss with ETH0,

Added log below.

~ # ### Application running ...

The possible reason for packet failures are "Failure NIC Card, Failure Cables, Changing to Different Switch/router or Port Speed Mismatch from Host to Target"

I checked with different switch Box,Lan cables and used mii-tool to change the speed of the Host PC to match with the ETH0 speed with the following cmd sudo ethtool -s eth0 speed 10 duplex full,
getting same issue with ETH0.

Please provide me the suggestion, I am excepting Issue is with PHY Port because same functionlity working fine with ETH1 Port with same setup, same kernel.

Please provide your suggestion

Thanks & Regards

Can you ping your nfs server (10.162.103.226) from your board.

Test your board if your board and your NFS server are located in the same NET. For example test your board using ipaddr=10.162.0.194, mask=255.255.255.0, gw=10.162.0.1 and rootserver=10.162.102.226.

Check setting for NFS on your host PC.

Have a great day,
Pavel Chubakov

Hi Pavel,

Thank you for quick reply.

1) When I am booting into the Bash shell using ETH1 , I can ping NFS server and log is as below

root@freescale-82xx:~# ping 10.162.103.226

root@freescale-82xx:~#

2) Target Board and Host PC are in the same sub net because when I am checking the

ifconfig of Target Board , it is showing Ip address of ETH1 in the same sub net.

Log is as follows:

root@freescale-82xx:~# ifconfig
eth0      Link encap:Ethernet HWaddr 00:10:ec:00:5c:5b
          UP BROADCAST MULTICAST MTU:1500 Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

eth1      Link encap:Ethernet HWaddr 00:10:ec:80:5c:5b
          inet addr:10.162.103.176 Bcast:10.162.255.255 Mask:255.255.0.0
          inet6 addr: fe80::210:ecff:fe80:5c5b/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
          RX packets:112594 errors:0 dropped:0 overruns:0 frame:0
          TX packets:40259 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:157060886 (149.7 MiB) TX bytes:6576714 (6.2 MiB)

With same configuration from Host PC and Board , ETH0 is showing as not responding

I changed in //etc/network/interfaces as "inet eth0 manual" but no use.

I had suspected the issue is with Network Congestion problem, so I had used local network from Host PC to

Target Board using Router , and I got the same Issue with ETH0.

Had Used the Static IP as "root=/dev/nfs ip=10.162.103.42:::255.255.0.0:::10.162.0.1::eth0 nfsroot=<rootpath> rw"

No luck.

Here are configs mentioned in menuconfig

CONFIG_NETWORK_FILESYSTEMS=y
CONFIG_NFS_FS=y
CONFIG_NFS_V2=y
CONFIG_NFS_V3=y
CONFIG_NFS_V3_ACL=y
CONFIG_NFS_V4=y
# CONFIG_NFS_SWAP is not set
# CONFIG_NFS_V4_1 is not set
CONFIG_ROOT_NFS=y
CONFIG_NFS_USE_LEGACY_DNS=y
CONFIG_NFSD=y
CONFIG_NFSD_V2_ACL=y
CONFIG_NFSD_V3=y
CONFIG_NFSD_V3_ACL=y
CONFIG_NFSD_V4=y
CONFIG_NFSD_FAULT_INJECTION=y
CONFIG_LOCKD=y
CONFIG_LOCKD_V4=y
CONFIG_NFS_ACL_SUPPORT=y
CONFIG_NFS_COMMON=y

Please suugest me the way that which way I should go ahead

Thanks & regards

Satish,.G
