Code gets stuck at configASSERT(0); after running for few minutes

[vishnu_illikkal]

I am using the STM32H735G-DK board

When i tried the Debugging at this file the code gets stuck.

configASSERT(0);  is the line at which the code is

Here:

 

 /* This should never fail !! */
 if (BSP_TS_GetState(0, &TS_State) != BSP_ERROR_NONE)
 {
 configASSERT(0);
 }

 

 So BSP_TS_GetState() is returning an error.

Take a look at what error it's returning.

Can you step into  BSP_TS_GetState() to see where it detects the error?

 

EDIT:

So maybe try instrumenting BSP_TS_GetState() (eg, UART output) and see what changes when it stops working ...

[vishnu_illikkal]

ok will check.

[vishnu_illikkal]

does anyone know how not to optimize out the values?
this is on by default.

Change optimiser level.

Make sure the value is used - eg, in a printf.

Make the variable 'volatile'

i used snprintf and got to see the error

bool STM32TouchController::sampleTouch(int32_t& x, int32_t& y)
{
 TS_State_t TS_State = { 0 };

 /* This should never fail !! */
 int err = BSP_TS_GetState(0, &TS_State);
 printf("%d",err);
 char buffer[50]; // Adjust the buffer size as needed

	snprintf(buffer, sizeof(buffer), "%d", err);
	printf("%s\n", buffer);

// event_log((char*)err, LOG_DEBUG);
 if (BSP_TS_GetState(0, &TS_State) != BSP_ERROR_NONE)
 {
 configASSERT(0);
 }

 if (TS_State.TouchDetected)
 {
 x = TS_State.TouchX;
 y = TS_State.TouchY;

 return true;
 }

 return false;
}

it was -5 which is BSP_ERROR_COMPONENT_FAILURE

So that must be happening here:

 /* Get each touch coordinates */
 if(Ts_Drv->GetState(Ts_CompObj[Instance], &state) < 0)
 {
 ret = BSP_ERROR_COMPONENT_FAILURE;
 }

So, again, instrument  that GetState function to see what it's returning, and why.

 

[vishnu_illikkal]

 int err = Ts_Drv->GetState(Ts_CompObj[Instance], &state);
 char buffer[50] = {0};
	snprintf(buffer, sizeof(buffer), "%d", err);
	printf("%s\n", buffer);
 if(Ts_Drv->GetState(Ts_CompObj[Instance], &state) < 0)
 {
 ret = BSP_ERROR_COMPONENT_FAILURE;

I found the error as -1 
but i couldn't fine the function 
i could only find the ts.h header file

It's a function pointer - so you'd have to find where that Ts_Drv structure gets initialised to know what actual function it's pointing to.

But there's no need for that: just use the debugger's "Step Into" and that will, as the name suggests step into the function - whatever it is.

[vishnu_illikkal]

i will try.
