I have some LPC1788 ICs. One of them is on Embedded Artist Development Board and another ones are on my boards.
I call SystemInit() function on Embedded Artist Board and everything is OK. But When I try to call SystemInit() on Myboards, program counter jump meanless locations and do meanless something. There is no Exception (Hardfault, Busfault etc.)

If I dont call SystemInit() Embedded Artist and My Boards Behaviors are same.

Can it be Oscillator problem? I have changed Oscillator on my board but result is same.
