AM5728: MCASP driver is crashed

Hi,

Is "mcaspAppCallback()" your interrupt service routine (ISR) called by SYSBIOS HWI when interrupt is triggered?

If yes, ISR function can only have one argument.

Please refer to SYSBIOS API reference guide for the prototype as shown below.

typedef Void (*FuncPtr)(UArg);

You can find the below example code in the API reference guide as well. In the line where the argument is set, you will replace it with "ioBuf" pointer.

  #include <xdc/runtime/Error.h>
  #include <ti/sysbios/hal/Hwi.h>
  
  Hwi_Handle myHwi;
  
  Int main(Int argc, char* argv[])
  {
      Hwi_Params hwiParams;
      Error_Block eb;
   
      Hwi_Params_init(&hwiParams);
      Error_init(&eb);
  
      // set the argument you want passed to your ISR function
      hwiParams.arg = 1;        
   
      // set the event id of the peripheral assigned to this interrupt
      hwiParams.eventId = 10;   
   
      // don't allow this interrupt to nest itself
      hwiParams.maskSetting = Hwi_MaskingOption_SELF;
   
      // 
      // Configure interrupt 5 to invoke "myIsr".
      // Automatically enables interrupt 5 by default
      // set params.enableInt = FALSE if you want to control
      // when the interrupt is enabled using Hwi_enableInterrupt()
      //
   
      myHwi = Hwi_create(5, myIsr, &hwiParams, &eb);
   
      if (Error_check(&eb)) {
          // handle the error
      }
  }
   
  Void myIsr(UArg arg)
  {
      // here when interrupt #5 goes off
  }

Stanley
