    Is anybody else having trouble getting the P&E parallel port BDM that came with the ColdFire M5475EVB kit to work? I’m trying to get it to work with the copy of Metrowerks CodeWarrior that was included. The IDE seems to recognize that the BDM is there and it attempts to interact with the processor, but it is intermittent at best. In the hardware diagnostics I can sometimes write and then read a byte from memory, but trying to load programs or anything else ends with complete failure. I might be thinking a naively, by I thought that after installing the drivers and software I should be able to connect to the 5475 and manipulate memory and registers right out of the box. Am I missing something? I went to P&E’s website and followed all of their recommendations for configuring XP and the parallel port, but that didn’t help. I’ve been in contact with Freescale without any success so far. Any feedback would be greatly appreciated, even if it is to tell me that yours worked fine right out the box without any tweaking.

    It turned out it was the parallel port cable that came with the kit that was causing the problem. When I switched to a cable I had lying around, all the problems vanished.

    Keith,

    I've verified that the BDM works as is with the cable that comes standard with the Freescale Kit. Perhaps there was something different in the process you tried with the other cable to get this result?
