Hi Vidya Sagar,

Can you please help me in enabling network stack in MPC8323E-RDB board.?

I had confused with following things.

1. After uboot.bin is loaded, trying to ping a device, which is present in my network, I am getting "Host is alive" (Kernel and rootfs is not yet loaded).

2. After loading Kernel image and rootfs, I am trying to ping a device, it is not responding. Even I ping my board from out side it is not responding. I given IP configuration settings in kernel, but I am not getting which is effecting this whether isn't network stack present in my kernel.?

Please respond as soon as possible.

Thanks and Regards,

Look at attached file.

Is recommended command sequence used on your board?

Check Ethernet configuration on your board. Use "ifconfig" command for Ethernet configuring under Linux.

Have a great day,

Sir,

I seen what you attached here. As mentioned in the "12. Using PCI and Mini PCI cards" section,

./ltib -m prep -p kernel-2.6.20-mpc832x_rdb.spec

can set network configuration in the board.?

Hi,

I might not explaining you my issue properly. Actually I am using MPC8323E-RDB board for developing applications. I have my company's own private LAN networ, so it's not required for DHCP. I configure boot network variables before loading kernel, dtb and root files. I tried to ping the netwok devices from boot prompt, "host is alive" is the reply. Then I loaded kernel, dtb and roof fs (result of LTIB process) into my board using tftp server. While building the kernel, I provide required network settings for my board. Now, I connected my board in the LAN and tried to ping this board from my pc, but it is not recognized. I tried to ping my network device from my board, here also no recognizance to my network device. Now, I am suspecting

1. whether the network stack is there in my board.?

2. Did I miss any network related package selection during kernel building.?

I checked for "/etc/network/interfaces" file in my file system, but it "/etc/network/" directory itself is not present.

I am using LTIB version: 7.4.1 (1.351).

My Pc loaded with UBUNTU 8.10

Please, suggest any solution to make up the network stack for my MPC8323E-RDB board.

Thanks and Regards,
