Lauterbach like Lego, constructing from modules: from dumb LPT<->jtg upto monster-alike in-circuit emulator (I didn't talk about how _much_ smb. will pay for it, I talk about possibility). >> Cons: >> BDI support gnu toolchain natively (in GDB server mode), > In other words: The BDI2000 fits seamlessly into a Linux based > development environment.

I'm not sure, since I doesn't work with Lb approx. 3 years, but probably it could. >> And you are know, hmm, strange Lauterbach price policy: >> price of BDI firmware for a new CPU target is approx. 1000 eur, >> for the Lauterbach - price of new device. > Another pro for the BDI: they have *excellent* support.

Don't asking them for a help, since my BDI work as predicted, so it may be pros also :). > Best regards, > Wolfgang Denk -- Regards, Andrey Volkov
