Hi guys, Just my two cents for this idea:
I think if we are to build something like this, and we plan for it to be ARM centric - just as openocd is atm -, I think we should think about hardware support for the full ARM Coresight architecture, in advance. What I intend to point out is real-time tracing. It is a very handy feature, even though the open-source world does not really have the tools now to exploit its features - or at least I don't know of any. As my thesis project I am currently working on a set of eclipse plugins that may be able to exploit some of the features, like real-time tracing of memory addresses and such, but as I am using the slow, UART-like interface, it will support only a subset of them. The parallel trace output of the trace peripheral is 4 bits, DDR, at Fcpu. That cannot / is very hard to be decoded without an FPGA. So at a core speed of 100MHz that is up to 800MBit/s data. Even though OpenOCD does not yet support the trace peripheral, I think we should plan ahead and design a hardware that will be able to capture the trace traffic when the software support is ready.
