Hi, we are using coldfire controller for ethernet application. Recently we are getting one issue that PLL is not getting locked. Due to this Phyclock is not getting generated. we are using 25Mhz crystal , when running the code it is going to illegal vector (program counter error vector number 4) where PLL is getting locked. verified the circuit and measured crystal also every this fine. Plz let me know what may be the problem.
