I agree that a generic solution is better, but.... We use the Abatron BDI3000 for our current project (using the bdiGDB firmware for the MPC5xx/8xx). If we want to use this JTAG/BDM with, say an ARM processor, we must pay Abatron appox. half the price of a new BDI when switching firmware.
Um... not really. Normally the price for the firmware alone is less than 40% of the price for the bundle BDI3000 with firmware.
Ok, I exaggerated. We payed 2500$ including firmware worth 950. That's 38%.
I think the cost here eats up the advantage of having a generic product.
Well, with hardware-specific products you always have to pay the full price. That's even worse. And probably your interfaces (including the user interface) are changing, too.
Most often yes, but how much interface changes regarding BDM communcation is there between, say 8xx and 82xx? I'm sure you know the exact details ;-)
