Here the TRST is asserted on the inside of the CPU(invisible to the outside). OpenOCD needs to know, otherwise it won't know to fall back to reset run_and_halt from reset halt. > Should it works with the LPC2148 target? I haven't tried it, but I believe so. I don't know if there are any embedded ice registers that OpenOCD can't or doesn't set that TRST does set to the correct state. Until proven otherwise, I assume TRST is needed for XScale though. Also OpenOCD can be used for e.g. FPGAs and I wouldn't want to speculat on what they need in terms of TRST. > > Regards, > > Michael > > -- Øyvind Harboe http://www.zylin.com/zy1000.html ARM7 ARM9 XScale Cortex JTAG debugger and flash programmer _______________________________________________ Openocd-development mailing list [email protected] https://lists.berlios.de/mailman/listinfo/openocd-development
