Wow terrific progress. I have been playing with the c2 also, exciting to see how fast things are moving for the c2.
possibly off topic now-
here is uart output from non booting c1 image
QA5:A;SVN:B72;POC:17F;STS:0;BOOT:0;INIT:10;BOOT:1;INIT:0;READ:41;USB:3;SERIAL:4;STS:0;BOOT:0;INIT:10;BOOT:1;INIT:0;READ:41;USB:3;SERIAL:4;
unable to fetch bootloader? quite possibly my sd card is bad...
