I don't think that AT91SAM7 can reset in halt... AT91SAM7 can't reset in halt, this means that it will     execute code in Flash before any JTAG debugger can halt the chip.
Best to use soft_reset_halt whenever possible and use "reset init" only when JTAG gets out of sync, i.e. when target is power-cycled.

Again I recommend you to use the openocd mail lists. You won't find OpenOCD experts here.
