LPC1124 HARDFAULT WHILE INITIALISING A PIN AS OUTPUT

[pascalcarreweyn]

i'm trying to make a simple led switch on or off with an LPC1124   P3.4

but when i'm initializing, i alway end up int HardFault_handler 

I have no idea what is wrong ?

/* Initialize GPIO */
 Chip_GPIO_Init(LPC_GPIO);

 Chip_GPIO_SetPinDIR(LPC_GPIO, 3, 4, true); // WHEN I DO THIS I END UP in HardFault Handler.... why is this ?

The same thing works for the LPC 11U37

If i try the same thing even with the blinky project i have the same error while debugging...

Hi pascal carreweyn

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
To provide the fastest possible support, I'd highly recommend you to use the demo in the LPC1125's LPCOpen library.

Hi Jeremy,

Thanks for the help but i already solved the problem.

It was a hardware problem with the debugging cable which gave me this strange effect...
