Well, it depends. A lot of work can be done with the BDM4GDB
adapters, as long as you restrict yourself to MPC8xx based systems.
But even then there wil be situations where you will be remembered
that it's a Do-It-Yourself solution, not a professional grade device.
The BDM4GDB is OK for the fatal case when you erased the flash by
accident, or for occasional debugging a problem. For professional
work I prefer to use a BDI2000 though. It's faster, it works more
reliably, and most of all it supports a lot of other CPUs as well
(CPU32/32+, MPC5xx/8xx, 6xx/7xx/74xx/82xx, 4xx, ARM7/9TDMI, ColdFire,
MIPS32, MIPS64, XScale, M-Core ...

I never used kdevelop and thus I don't know about it, but you can use
_any_ debugger frontend that communicates with GDB. DDD works just
fine - with the BDM4GDB adapter, and with the BDI2000.

Do not follow where the path may lead....go instead where there is no
path and leave a trail.
