I find that I can programme the LPC930 only once - after that it becomes useless. It will not run the programme, and it does not respond to the external switch that is supposed to bring it back to ISP. I am using the on-chip oscillator and RST is tied high.
I am using Flash Magic v2.07 (9600 baud) and have used the same programme and ISP set up successfully with the 932. The ISP code protection is on.
Is there any difference between the 932 and the 930 that could cause this problem.
The chip part is 89LPC930FDH
