"Trouble Reading Memory Block at ...

Posted by Mohammad on February 25, 2012
Hallo Everyone,

i have again another problem:
i am using TI MSP430f5438 with code composer:

i create receiving-task and a sender ISR is already given in Hardware Abstraction Layer "HAL".
after the first sending and receiving, the second sending is not working well.

here is the sending ISR:
#pragma vector=USCI_A1_VECTOR
__interrupt void USCI_A1_ISR (void)
{
char cChar= NULL;
portBASE_TYPE xHigherPriorityTaskWoken = pdFALSE;
cChar = UCA1RXBUF;
xQueueSendFromISR( xPROTQueue, &cChar, &xHigherPriorityTaskWoken );
__bic_SR_register_on_exit(LPM3_bits);
}

with the debuging and making Step into i found that the code stops at this ISR in port.c :
#pragma vector=configTICK_VECTOR
interrupt void vTickISREntry( void )
{
extern void vPortTickISR( void );

#if configUSE_PREEMPTION == 1
extern void vPortPreemptiveTickISR( void );
vPortPreemptiveTickISR();
#else
extern void vPortCooperativeTickISR( void );
vPortCooperativeTickISR();
#endif
}

and then i get this error:

MSP430: Trouble Reading Memory Block at 0xca5a4 on Page 0 of Length 0xc9: Invalid parameter(s)

can anyone say what the problem here can be.

Best Regards,
Mohammad
