We have currently build our Baseband board using OMAPL138 chipset. We have built around 100 boards. Initially the OMAPL138 was configured atr 300MHz with Core voltage of 1.2V. Recently we have increased the CPU frequency to 450Mhz and we are seeing the chipsets getting damaged. On Further probing we have seen that there is short seen in DVDD3318_B group of pins w.r.t to Ground. All the OMAP devices which are being used are capable of running at 450MHz . Any pointers in debugging this will be very helpful for us.
Thanks in Advance
