Hi... I was using Keil Version 3.72.. but now upgraded to 3.90. The problem now i am facing is that, the program works well in debugger but when it is flashed on to microcontroller (LPC2129)...it doesnt work....The thing i understood is the change in start up code.. In reset condition, the PLL in system control block of Keil shows that XTL and Clock frequency is 12MHz. I wrote a pgrm for PLL...and the problem exists...
Plse help................
