side information: i've started porting serialice to my board, which lets you step through bios firmware and try different images without removing the chip.

I got two new sockets in the mail, and a new breadboard. I wired them up but it's still not working. I'm not using the breadboard yet, because the sockets have square pins and I don't want to add points of failure.

The most likely candidate for misbehavior is atm the teensy flasher i'm using. This flasher's code is open (the teensy's seems not to be, unsure) was recommended by the community, but they all use internal flashing themselves. There are flashers using the same code for a beagleboard and a raspberry pi.

I'm thinking a reasonable next troubleshooting step would be to try swapping teensies out. I also have interest in doing the teensy programming on another system, for convenience and to consider bisecting the system it's connected to as a failure point.

It's hard to track possible issues with the wiring, with 32 wires and my hands spasming. It would seem easier on a breadboard. I think it would be helpful to label each wire.
