[psas-avionics] GFE layout is pretty much done.

Hi Dave,

> 1) do they have a JTAG header on them?

No, you don't get JTAG. Instead, you have to write your own I2C over USB
bootloader. And no cheating: it's got to be written in assembly.

Yes, there's access to JTAG, as well as UART0 for ISP, and three debug
pins, all on our very own debug connector.

I am ashamed to admit that I didn't specify a tri-color LED like I did
on the FC. I must go rectify my grave, grave error. ;)

No, not really. There are three GPIO lines on the debug connector, so
you could break those out to LEDs. or, just use a bunch of the open
lines... theses things have tons of GPIO broken out.

Try not to.
