I am developing on an NXP LPC2103.
I do not routinely use JTAG debugging, but use the crash and burn approach most of the time.
I therefore program using the Philips Flash Utility rather than programming the flash over JTAG.
I have noticed that I can attach the Signalyzer and still program the LPC using the Serial port.
As soon as I have used OpenOCD, I can no longer program using the serial port even when OpenOCD is no longer running.
I assume OpenOCD leaves the FTDI chip in a different state to how it found it. If I unplug the Signalyzer from my USB port and plug it back in again I can then resume programming the Flash by the serial port.
Is there an existing option to stop this behaviour or would it need a patch ?
Cheers.
