I recently received my board and went through the QuickStart procedure. Everything works just fine there.
Now I want to configure my host as an NFS server and boot the u-Boot kernel image (uImage) via TFTP. I had to configure my u-Boot settings to use static IP (not sure why I couldn't get DHCP to work). My boot-up process seems to load the uImage just fine, but stops at the "Sending DHCP requests ..."
Not sure if I have to reconfigure the kernel or if this is an NFS issue. I am using the OMAP PSP tools from TI, and have used their uImage per these instructions:
http://wiki.davincidsp.co..._Target_File_System. I have configured my /etc/exports file and know NFS server is working because I have gotten it working on other ARM and SBC systems. Perhaps someone has some insight?
I am posting my u-Boot settings and my screen output:
