running lpc82x periph_adc example getting HardFault_Handler everytime.

[chestertai]

I am using LPC82x xpresso v2/mbed development board and running the periph_adc example.  After enable ADC sequencer

Chip_ADC_EnableSequencer(LPC_ADC, ADC_SEQA_IDX);

The program will jump to HardFault_Handler.  Anyone seen this happeded?

  Hello Chester! 

As I mentioned in the case, the problem is in the file cr_startup_lpc82x.c since it lacks some interrupt handler. The example of the ADC provided in the code bundle works fine. If you compare the file mentioned before with the same one but of the code bundle you will see the differences, as shown below. 

Please replace all the lines in the cr_startup_lpc82x.c file of the LPCOpen 3_02 to match the one of the code bundle. Once you make these changes the demo should work as expected. 

Hope it helps!

Victor.
