k70FN1M0 can't flash, MCU locked

Hi Freescale,

 

I am developing a large firmware project, using a K70FN1M0 running MQX 4.0 and developing with CW 10.5.

 

I have always been able to build, flash, and debug successfully. However, today I tried to flash the MCU via PE-micro USB-multi-link connection (as I always have), and got the notification "Warning device is secure. Erase to unsecure? ". I clicked Yes to continue with the process, and immediately lost connection with the processor, as if I had unplugged it. The processor is getting power, and the USB-multi-link connector recognizes the hardware connection (yellow LED on), however CW can't seem to connect to the device (see image).

 

Please help! Has anyone ran across this issue before?

 

 

Best,

Brett
