Well, don't cry just yet. I plug in my Minty, slap a CF card in there, and open my terminal program. Turn minty on, and I get the following:
Minty MP3! v1 3/25/2004
Resetting Card.. found CF card... Identifying CF..
After that, nothing.

...Think I'll call it a night, but at least I'm encouraged to keep trying, instead of shelving the project :-)

im almost positive that a pin on either the TQFP or the CF header isnt soldered properly...

This is a CF card I've been using in my YAMPP :oops:, which is formatted in some custom YAMPP filesystem. Maybe Minty can't detect it if it isn't FAT16 (or whatever)?

Couple of things.
1. just now ( after a few months of on and off work, I discovered that
the place that I got the pcb fabbed from as a prototype(pcbfabexpress).. had issues with the tolerances(probably had to do with clearances around the vias).. and as a result... on of the via's that goes to ground from the top layer from the ftdi chip isn't actually connected(1565,650).. I'm thinking I may try a wire bypass to a known good ground and see what happens.

2. I actually procured an oscilliscope and want to know about in what voltage range the crystal should be oscillating at/if you should be probing inside/outside the capacitors(if it matters)
