LPC1788 is going crazy(No Exception) after calling SystemInit() function.

Hi,

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.

Thanks.

Murat.

Hi Al Bradford,

Thanks for your response.
My problem is wrong Inductance on VSSA pin for LPC1788.
Inductance has big DC Resistance. When We remove it and make short circuit my IC start to works fine.

Thanks.

Murat.
