Hi! I am making LPC2468 as a usb host.. The circuit is ready... I am programming it serially using Flash Magic and MAX3232.I just wrote a sample code for making port pins 2.18 and 2.20 a logic low as all pins in LPC2468 are pulled up by default. The program showed no error and it gave satisfactory output when I simulated it. Also, no error in downloading it through flash magic..After loading, I took the ISP jumper out and unplugged the power from the circuit and again powered it up with a thought in mind that controller will get reset by doing this and execution will start from 00000000memory location... But this didn't happen.. My controller,though program being loaded successfully,is not executing the program,i.e the pins 2.18 and 2.20 are not getting low.. Please help me to find remedy to this..
