Phil had partially implemented OTA re-configuration, and we started experimenting with it in the field for arctic pisces.
However, the code to receive it doesn't quite work yet. I added a few debugging printouts (without the iridium repeater, our most reliable way to test it was to put a buoy outside, send a message, then pull the buoy back inside and look at logs after the first waves message came through.) It appears that the problem is in the iridium code's implementation of __uart_read_dma; for some reason, the uart is busy when it makes a call to _Receive_DMA, so we don't ever get the received message from the modem. On first read, I'm not sure why it's busy there -- if we got to that point, the previous ..._Transmit_DMA should have already finished.
Here's the complete BOOT.log from the test with the best debug output, from microSWIFT 209 sitting in the buoy farm running V2.09_rc5 firmware.
