Hello,

I have a problem and i don't know the way to find the solution, it is why i search help.

We made a LPC11E68 board, with LPCXpresso, LPCOpen 2.11.
We made our board library and import the chip library.

For the first program is to troggle a led.
The program compile and run in debug mode.

But in the PLL initialization, i have a HardFault.
It's strange because it's on the function return (Sceenshoot joined).

We are using a 16MHz crystal.
The good frequency is set in the board library.

I don't know where is the problem.

Any advise is welcome, Thanks a lot.

Regards, Philippe.

Did you change PLL settings for 16MHz :quest:

You are rigth !

I miss one param in sysinit_11u6x.c
This is the change setting in Chip_Clock_SetupSystemPLL(2, 1);

Thanks.
