Hello Panagiotis,
im intersted in the development tools for MPC555...MPC565.
Whichs tools are you using ?
(free assembler,Debugger,Monitor,Flasher...)
(please mail me saschaspeedy@hotmail.com)

But for my highspeed solution without an FPU
I will use Cygnal (100Mips...!!)
The MPC works with 20Mips and 32bit is not for all application importend.
But 64bit Floating Point FPU thats realy great.

Sascha
