Hi,

I have the ISP pin on a custom board connected to a pushbutton via a test fixture pogo pin: there is no pull-up on the pin. I am finding that activating the ISP causes boards to fail: the pin shorts to ground internal to the LPC, and the LPC becomes bricked because afterwards it always boots to the bootloader. Is this a know problem, have others experienced this, is there a cure going forward?
