Ok, glad the MRAM is working. Any chance that you don't have the two jumpers on the LaunchPad required to power the 5043s? These would be a pair on the right (components up, USB down, I think) just below the bottom set of pins.
BTW, I don't even try to push Jim's board all the way on. It is tight as it is and I want to be able to get it back off (relatively) easily. But regardess, the tops of the pins are all level, even though the newly soldered pins have a plastic holder at the bottom and the original pins do not.

Burns sent me the info on that. I ran J5 pin 12 to a via on the bottom right of U1. After doing that wiring change, all but one MRAM appears to be working. It looks like R5 got removed somehow, I may have done that removing the wire. I just installed a bridge there, since it's a zero-ohm resistor, and the mram seems to be working now.
The temperature sensor on the daughter board seems to be working.
I don't think the 5043's are working. I'm not getting anything on transmit, and I eventually get:
Pacsat>send pb status ## SELF TEST: pb_test_status TX QUEUE FULL: Could not add UI frame to Packet Queue PB Empty. ## PASSED SELF TEST: pb_test_status
after running that a few times. At startup, I'm getting:
ERROR: In start_rx, axradio_init returned: 5 ERROR: In start_tx, axradio_init_70cm returned: 5Initializing PB Task ERROR: Failed in init PB Status Timer

Chris,
Please take a look at the email I sent out earlier. There is the possibility of a wiring error on the board with my white
wire correction.
As for the connectors being longer, I never noticed that and these
should be the same connectors I sent Burns and Chris.
Burns say the MRAM is working after the wiring change and the AX5043s
are working for Chris and Burns so not certain there.
Attached is the revised schematic. I'll have the Kicad files on github
hopefully tomorrow. Have a couple of issues to deal with.

I sent this earlier, but just to Chris.
I got my board today and soldered on the connectors. Looking at the
board now, I see that the connectors that came with the launchpad are around 1cm longer than the ones Jim supplied. I can't get the mram or ax5043s to be detected. I don't think it's making good contact on the connectors, for obvious reasons. Do I need to trim the old connector, or did I do something wrong?
I clipped the pins, and still no help. The power light by the serial
connector works, and the serial port works. But the mrams and the ax5043's are not there.
I can't find the schematics in the git repository. PacSatDocs, I
assume. I guess I need to start debugging to figure out what is wrong.
