I finally got a FTDI cable and attached it to my new BBB. I get the following when I attempt to boot from the microSD card:

Booting from nand ... no devices available no devices available Bad Linux ARM zImage magic! This seems to indicate the zImage is bad on the microSD. However, I tried this microSD card in two other BBB's that I have, and they both boot just fine from this microSD. And, I took the microSD card from one of those BBB's (a known good card), put it in my new BBB, and it won't boot. So I think my new BBB is defective.
