LPC1768 Clock Issue

domneck — Thu, 24 Nov 2016 16:37:28 GMT

Hello engineers,

We trying to debug/program a LPC1768 but there is something wrong and we are out of ideas. We created a project to blink led and when programming the chip with JLINK everything seams to be ok even after verifying. When we start the debug session in LPCXpresso we are getting HARDWARE FALUT.
Board is not getting Clock.

Same we tried with segger software its fine LED is blinking.

Hi Domneck S,

This question should be the same problem in your another post:

LPC1768 HardFault

Please check the MCU setting in yoru LPCXpresso, besides, you can try to use the official lpcopen code for LPC1768:

LPCOpen Software for LPC17XX|NXP

But before you run the lpcopen code, you should check whether your on board external crystal is the same as the lpcopen defined.

Wish it helps you!

If you still have question, please let me know!
Have a great day,
Kerry
