Everything was going well. I was debugging my code, compiling and downloading without any problems. And then on the last try the Due ran the next to the last downloaded program, not the latest I just downloaded. In the download progress log was this:
Open On-Chip Debugger 0.9.0-gd4b7679 (2015-06-10-22:24) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html debug_level: 0 adapter speed: 500 kHz adapter_nsrst_delay: 100 cortex_m reset_config sysresetreq Error: unable to find CMSIS-DAP device Error: No Valid JTAG Interface Configured.
Now it can't find something? And why is it concerned with JTAG? I am not running any hardware connected to the JTAG interface, it it has one. I re-booted my PC running Win10 and cycled power on the Due. Still stuck here.
