I have just installed crossworks V2.0.2 on my win7RTM laptop.
I finally ( bought it 2 years ago) installed my Olimex ARM-USB-OCD as the downloader/debugger.
I have to say, it is wonderful, just selected it as the target, and away it went.
I am used to PIC debugging using its ICSP, and the ARM/Rowley solution is like day and night.
Its fast at programming using the JTAG, the tracing/breakpointing is fantastic.
I have tried to get into ARM for a while now, and this is the kick I needed.
many thanks to Paul Curtis of Rowley for his excellent support
