Error resetting hardware interface

Hi,

Im having some small starter-problem with my Freescale M52235EVB board with the USB ColdFire Multilink rev D. The debugger is connected to my PC and everything is installed (blue and yellow light is on), board is set to BDM. But when I choose the PEMICRO_USB with USB_0 in CodeWarrior Preference, and press debug, I get the error "ColdFire PE Protocol Adapter: Error resetting hardware interface, maybe try a different port". For USB_1 to USB_3 I get the "please select a port number within valid range..." error.

Am I selecting the port correctly? Why are there no connection to the ColdFire processor?

Anyone?

I have tried using Testcfz and copied the new unit_cfz.dll to System32 with no luck. Testcfz says FAILURE, Could not force processor into background mode. CFFlasher says the same thing (even tried using different Speed-settings).

Searching this forum for "Error resetting hardware interface, maybe try a different port" finds this previous post:

Let us know if anything in there fixes your problem.
