failed to excute MI command -data--disassemble -s -e

[xin_ma]

when running led_blinky example on N947, I use step over to debug, and came cross this bug:

00002cb0: Failed to execute MI command:
-data-disassemble -s 11440 -e 11488 -- 3
Error message from debugger back end:
Cannot access memory at address 0x2cb0

and the debug session won't go on.

this happens in this part:

while (1)

{

/* Delay 1000 ms */

SysTick_DelayTicks(1000U);

GPIO_PortToggle(BOARD_LED_GPIO, 1u << BOARD_LED_GPIO_PIN);

}

Hi, @xin_ma 

I am not repeating the problem you mentioned, I am using the latest version of SDK2.14.0 and MXUXpresso IDE 11.9.0. I see that the latest version of led_blinky is the LED that is triggered in an interrupt, but this error should not occur if placed in while, I suggest re-importing the project and trying again. Here is my code reference:

#include "pin_mux.h"
#include "peripherals.h"
#include "board.h"

/*******************************************************************************

 ******************************************************************************/
#define BOARD_LED_GPIO     BOARD_LED_RED_GPIO
#define BOARD_LED_GPIO_PIN BOARD_LED_RED_GPIO_PIN

void SysTick_Handler(void)
{
    /* Toggle pin connected to LED */
    //GPIO_PortToggle(BOARD_LED_GPIO, 1u << BOARD_LED_GPIO_PIN);
}


void SysTick_DelayTicks( __IO uint32_t ms)
{
  uint32_t i;
  SysTick_Config(12000000/1000);

  for(i=0;i<ms;i++)
  {
    while( !((SysTick->CTRL)&(1<<16)) );
  }
  SysTick->CTRL &=~ SysTick_CTRL_ENABLE_Msk;
}

/*!
 * @brief Main function
 */
int main(void)
{
    /* Board pin init */
    CLOCK_EnableClock(kCLOCK_Gpio0);
    BOARD_InitPins();
    BOARD_BootClockFRO12M();
    /* Initialize the systick module. */
    //SysTick_Config(12000000UL);
    LED_RED_INIT(LOGIC_LED_OFF);

    while (1)
    {
    	SysTick_DelayTicks(1000);
    	GPIO_PortToggle(BOARD_LED_GPIO, 1u << BOARD_LED_GPIO_PIN);
    }
}

Hope this helps you.

Best regards, Alex
