Problems with booting 547x development board using NFS.

hopdog — Sat, 07 Feb 2009 05:11:51 GMT

I'm having issues with booting using NFS. After setting up eth0 it looks like it can't find the NFS mount anymore. I've looked at my ip config and boot args values in u-boot and they look fine. Any suggestions?

Here are my u-boot environment vars

I am using the stock uImage file from Freescale.

A couple of things to try:

- try and ping the server (10.210.65.155) from u-boot
- is your ltib network target setup for static IPs or DHCP

Are you using the LogicPD 5475EVB ?

I had a typo in my subject. I'm actually using the 5484 Lite eval board. I bet part of my problem is that the default image is built with a different network configuration. Could this be the problem? If so, I've got another problem. I have rebuilt the ltib project and successfully tftp'd it to the dev board and then tried to bootm it. When I do this my seial console goes wacky. Could this be do to the baud rate being modified do boot? If so where do I set it, in initab? What params would I use ?

Try taking a look at FAQ-28688, which describes a similar problem with a BSP booting into NFS. Perhaps it will provide some insight.

I've managed to get it loaded and running. The problem was that the ltib image output was being put into the wrong directory. Now, that it loads and executes can anyone point me to some basic demo app build instructions/app notes? Also, what is the default username/password to telnet into the target?
