OpenOCD run program from flash problem

Hi,

it seems for me like a breakpoint isn’t blocking the execution of my (simple blinkled) program

It doesnt do a thing (doesn’t blink and also doesn’t produce serial debug output).

wrote 32768 bytes from file bin/getting_started_sam3-h256_sam3s4-flash.bin in 2.941670s (10.878 KiB/s)
verified 21936 bytes in 1.281859s (16.712 KiB/s)
target state: halted
target halted due to breakpoint, current mode: Thread 
xPSR: 0x61000000 pc: 0x2000002e msp: 0x20002a1c
shutdown command invoked

See whole flash procedure in attachment.

Setting:

  • - gnu make – running with
  • - arm-none-eabi-gcc (Sourcery CodeBench Lite 2011.09-69) 4.6.1
  • - Open On-Chip Debugger 0.6.0-rc1
  • - SAM3-H256 (ATSAM3S4BA)
  • - ARM-USB-OCD-H

    Looks fine to me. OpenOCD has programmed/verified your target etc.

    Now all you need to do is cycle the power or issue a reset to OpenOCD.

    Hi Spen,

    Ok, so the problem is rather in the .c code than in the flashing process... [attachment=0]main.c[/attachment]

    Tried it before, but with the same outcome

    Thanks for your help.

    File attachment isn’t working so:

    /** \file main.c
*/
#include "board.h"
#include <stdint.h>

static void _Wait(unsigned long delay) {
    uint32_t elapsed;
    do {
        elapsed ++;
    }
    while (elapsed < delay);
}

int main(void) {
    uint8_t en_led = 0;
    LowLevelInit(); //don't know what this does

    //Configure LED PIOs
    LED_Configure( 0 );

    while (1) {
    	    if(en_led == 0) {
    	    	en_led = 1;
    	    	LED_Clear(0);
    	    } else {
    	    	en_led = 0;
    	    	LED_Set(0);
    	    }
	_Wait(2000000);
    }
}

    It’s solved!!!

    It was an failure in the low lvl initialisation (http://www.mikrocontroller.net/topic/245304)

    Thx
