  before i put the zedboard aside a couple days ago to finish another
short project, i tried those images and anything else i could think of
to verify that this zedboard is in fact alive, with no success.

  i've tried different images, formatted the SD card in a variety of
ways, connected my fedora system to the UART port with both minicom
and picocom, verified the various board jumper settings to boot from
SD card ... the only indication i get is the power LED when i turn it
on. when i get home in a couple days, i'll take another shot at it but
i'm running out of ideas.

  to keep things simple, i don't even want to boot to linux -- i want
to stop in u-boot to poke around so, AIUI, i really need just the the
files BOOT.BIN and image.ub on the SD card, yes?

  i found this set of instructions for the microzed:

http://zedboard.org/content/how-copy-bootbin-and-imageub-over-sd-card

so based on that, this is my plan for the zedboard when i get back:

1) format an SD card, partition /dev/sdb1, WIN FAT32 (?)

2) populate with only BOOT.BIN and image.ub

3) connect from fedora via /dev/ttyACM0, using minicom or picocom to
   UART port

4) do *not* connect anything to JTAG (i should not need it, right?)

5) verify jumper settings to boot from SD card

  i'm trying to do the minimal amount necessary to just get to u-boot
or, even simpler, just to have the board prove it's doing *something*.
i'll report back, and i'm still open to what i might be doing wrong.
