AM5729: U-Boot DHCP command fails after BOOTP broadcast command times out

Hello,

I am trying to get my new TI AM5729 Industrial Development Kit working. I'm able to boot off of an SD card, but my attempts to boot using TFTP, and also to use a shared NFS file system, have failed. Both fail on the "dhcp" command. I've attached below both the terminal output from the last part of the setup script, and the minicom session where I see the issue. My TI board is connected to a Linux Ubuntu machine through JTAG and also through one of the Gigabit Ethernet ports. The Linux machine is not connected to the outside world. Let me know if I need to change my physical setup and try again.

Below is the output from the setup script, the minicom session, and the results of a "printenv" command from U-Boot.

Would you like to create a minicom script with the above parameters (y/n)?

Detecting connection to board... /dev/ttyUSB2

--------------------------------------------------------------------------------
Would you like to run the setup script now (y/n)?

Please connect the ethernet cable as described in the Quick Start Guide.
Once answering 'y' on the prompt below, you will have 300 seconds to connect
the board and power cycle it before the setup times out

After successfully executing this script, your EVM will be set up. You will be
able to connect to it by executing 'minicom -w' or if you prefer a windows host
you can set up Tera Term as explained in the Software Developer's Guide.
If you connect minicom or Tera Term and power cycle the board Linux will boot.
