You know, that's interesting. We're using a BDI2000 with an mpc8343 here, and have to set the processor to a pre-defined mode to initially flash a RCW in, then set it back to loading from local bus after we have a valid word programmed. We've followed Freescale's guides on how to connect the COP port to the CPU, but have never gotten past switching modes to program the RCW.
I'm not a hardware guy, so I can't tell you if you're doing something wrong or even if Freescale's guides (which I have not read) are complete.
I can say that I haven't had any real problems with the BDI-2000 on any Freescale reference board I've used. However, creating a BDI-2000 configuration file is tricky, especially if you're debugging U-Boot. U-Boot will generally not boot on a board that has had some BDI-2000 pre-programming (i.e. stuff in the [INIT] section). So I usually have two configuration files: one just for flashing, and the other for debugging early U-Boot.
The one for flashing will initialize the CPU, DDR, and flash memory.
