Hello,
  I have a LogicPD Zoom AM3517 experimenters board.  Is this the
correct list to ask questions about getting Yocto-based software
running on this board?

Yes, this is one of the correct lists for asking questions about AM3517 board
when used with the Yocto Project. :) As this is the mailing list for meta-ti,
which is the official Texas Instruments BSP layer for OpenEmbedded-Core and
the Yocto Project, and AM3517 is currently one of the supported platforms in
meta-ti.

Wonderful.  Can someone point me to information so that I can build
a system using the Yocto project and program an SD card with the
necessary files to boot my board into Linux?

  With all of the S7 DIP switches in the off position (which the
AM3517 Development Kits User Manual indicates is the default boot
from NAND) I don't get any output from the serial UART so my guess
is that I've hosed the NAND.

  For debugging support I have a TI Stellaris LM3S8962 board which
has the ability to act as a JTAG debugger to external hardware.  For
software I have OpenOCD 0.6.1

I would assume you already checked this Hardware Setup page:
http://processors.wiki.ti.com/index.php/GSG:_AM35x_EVM_Hardware_Setup

Then you would need to check the Boot from SD/MMC page:
http://processors.wiki.ti.com/index.php/AM35x_EVM_Boot_from_SD/MMC_card

As of the software load, you can build a minimal rootfs image (e.g. 
core-image-minimal) with all the BSP components and setup an SD card as 
described above. You'll get the MLO, u-boot, uImage and rootfs as the
output of the build, that you need to load on to the card.

This gets me much farther.  I get the following on the serial port:

From this I conclude that my hardware is at least partially functional, my SD card is compatible with the AM3517 board, my serial connection is functioning, and I have at least the basics of getting the bootloading code (MLO) and u-boot onto the card.  

I suspect I need to change something in the /home/yocto/poky-danny-8.0/build/conf/local.conf file (probably MACHINE) to specify the correct hardware. I also need to figure out how to get the root file system written to the second partition of my SD card.  I couldn't find that information on any of the above mentioned pages or on the pages to which they have links.  My SD card is partitioned like this:
