I just powered up a ChipworkX module to erase and update the CLR and I think I might have bricked it. MFDeploy detected it so I erased the CLR and managed code area, and then MFDeploy crapped out. That was because it was no longer able to communicate through USB to the ChipworkX module. I tried changing the Up,Down,Select pin polarity to bring it up in boot mode to no avail, my computer does not detect it as a USB device.
Again here are the steps I took in MFDeploy:
Powered up ChipworkX (Up,Down,Select floating)
Selected USB as the communication interface
Pinged the ChipworkX module, it responded correctly
Clicked the Erase button, it start erasing but after about 5 seconds MFDeploy crashed
