Hi I am having start up problems with lpc23xx devices. i.e sometimes the CPU does not start my code when power is connected I activated brown out by changing PCON register and the situation got better when I reduce the pull up resistor or the capacitor I have on the reset pin, the situation gets better
Finally I removed the capacitor and the was only a 39k pull up resistor on reset pin and the problem was solved. The core was starting normal operation each time I connected power
My question is that will this cause a problem if I don't use a capacitor on reset pin? What other solution do you suggest to solve this problem?
