    Could ST confirm if the jtag cell is reset when RSTIN is asserted, this would explain what i am seeing.

    Regards

    I am working on an open source project called OpenOCD -

    http://developer.berlios.de/projects/openocd

    This is a arm7/9 debugger/programmer gdb/telnet server.

    One of the methods of halting the program from hardware reset is to set a breakpoint on 0x00 and reset device.

    This works if the jtag cell is not reset under device reset.

    For the str7 a software reset will have to be used instead - simliar to the lpc devices.

    Regards
