Once the VM problems were cleared, I've been playing with various coding experiments. Maybe a dozen. At one point, the LED on the LPC1769 side seemed to stick on half intensity (as if it's toggling at a high rate), and from that point on, I get errors like the following when I debug:

15: Target error from Commit Flash write: Et: Flash driver not ready.

Weird. So I reset the USB (dfu, reset the port in the VM) and try the command line:

highline-linux:/usr/local/LPCXpresso/bin> crt_emu_cm3_nxp -flash-erase -pLPC1769
Ni: LPCXpresso Debug Driver v2.0 (Apr  1 2011 10:54:24)
GetModuleFileName path == /usr/local/LPCXpresso/bin/crt_emu_cm3_nxp
Nc: Looked for chip XML file in /usr/local/LPCXpresso/bin/LPC1769.xml

Nc: Looked for vendor directory XML file in /usr/local/LPCXpresso/bin/nxp_directory.xml

Nc: Found generic directory XML file in /usr/local/LPCXpresso/bin/crt_directory.xml

Ed:02: Failed on connect: Ee(05). No matching emulator found - make sure power is on and not in use already.
Et:31: No connection to emulator device

Nothing. It seems to be in a programmed state from which I can't flash my way out.

I have tried other USB ports, etc.
