I suspect that many of those speed improvements can be had even with a CPU-based solution ... if the CPU is driving the JTAG interface directly, it can do things like handshaking in microseconds, not the milliseconds that a USB roundrip takes. In terms of Open processes, I can imagine doing that with various microcontrollers that come with USB (or Ethernet) links. It needn't be all that more pricey than an FT2232H dongle. Consider a board: USB --> Cortex-M3 --> level shifting --> JTAG Wouldn't be as fast as an FPGA, necessarily, though if the level shifting were packaged in a CPLD there might be scope to offload some of the most common handshakes. Come up with such a board with initial "it works" firmware ... and OpenOCD could speed things up over time. - Dave _______________________________________________ Openocd-development mailing list [email protected] https://lists.berlios.de/mailman/listinfo/openocd-development
