As I mentioned in another article, ARM Cortex-M3 is not compatible with ARM7TDMI in interrupt, ISA, bus structure and JTAG protocol (SWD). You have to upgrade ARM7TDMI tools to support Cortex-M3 microcontrollers. After a small research, I summarize following tool related information for your reference.

For those of you new to 32 bit or you are just learning PIC32 I highly recommend the PIC32 starter kit. For $50, the starter kit has all the software tools and hardware you need to experience the PIC 32 development environment.

USB-Stick as development systems

It's the fad of the moment and, we, as designers, do love these Gadgets! But what they are? Are Development Tools in USB Stick format simply toys or are they offering a complete and reliable debug system?
Surely the latter, because the capability (some of them have an ARM on board) and the versatility make a quality product highly useful for the developers.
