Hardfault handler infinite loop

[Erwan03]

Hello,

 

I am currently using a Nucleo F446RE board and i am facing problem while trying to read an analog pin using ADC functions. When i start running or debugging the project, i immediately fall down into Hardfault_handler function. I don't know what i exactly did wrong, and don't know how to figure it out...

 

Thanks in advance for help!

 

Please find attached the main file i wrote.

Hello,

At a first glance you declared this table with one element:

uint16_t uiADCRawValueBuffer[1];

  Then you access two elements.

uint16_t uiADCRawValueBuffer[1];

		for (int var = 0; var < 2; ++var) {
			uiADCRawValueBuffer[var] = HAL_ADC_GetValue(&hadc1); // Store converted values
		}
		buffer_throttle = uiADCRawValueBuffer[0];
		buffer_brake = uiADCRawValueBuffer[1];

  Please check.

Hello SofLit! hope you're doing well!

Ok then i changed 

uint16_t uiADCRawValueBuffer[1];

to

uint16_t uiADCRawValueBuffer[2];

so i have enough element in this array. But i am still stuck with same problem. Cannot debug nor Run. 

Let's start with only 1 analog input. Throttle one.

Not obvious to find the problem with the info you provide.

This kind of issue needs a debug. So go step by step and find at which step you get the hardfault. 

You can comment out the code and uncomment line by line and find at which level the hardfault occurs.
