hi every body,
this is my first time i use arm processor
i bought a board from olimex SAM9-L9260 I read the examples from olimex websites but it doesn’t run on the board
it has linux on it and i try to write a code in c then in compile it by the cross compilers and by the usb i copy it to the board but the code doesn’t run it give segmentation fault
what i tried to do is to turn on a led in portb
here is the code and plz tell me my fault
include “AT91SAM9260.h”
//#include “AT91SAM9260_inc.h”
#include “test.h”
#include “bits.h”
#include “lib_AT91SAM9260.h”
AT91PS_PIO p_pPioA = AT91C_BASE_PIOA;
AT91PS_PIO p_pPioB = AT91C_BASE_PIOB;
AT91PS_PIO p_pPioC = AT91C_BASE_PIOC;
AT91PS_PMC p_pPMC = AT91C_BASE_PMC;
AT91PS_RTTC p_pRTTC = AT91C_BASE_RTTC;
void delay(unsigned long a)
{
while(–a!=0);
}
int main()
{
bool set_port=false;
p_pPMC->PMC_PCER = 1 << AT91C_ID_PIOB;
//p_pPioA->PIO_PPUDR = 0xffffffff; // Disable Pull-up resistor
p_pPioB->PIO_PPUDR = 0xffffffff; // Disable Pull-up resistor
// p_pPioC->PIO_PPUDR = 0xffffffff; // Disable Pull-up resistor
//LED STAT
p_pPioB->PIO_PER |= BIT10; //Enable PA6
p_pPioB->PIO_OER |= BIT10; //Configure in Output
while(true)
{
if(set_port==false)
{ p_pPioB->PIO_SODR |= BIT10; //set reg to 1
set_port=true;
}
else
{
p_pPioB->PIO_CODR |= BIT10;
set_port=false;
}
delay(500000);
}
return 0;
}
this code i compile it by the cross compiler and put it on board
the compilation succeed but when i run it it give me segmentation fault
plz any one tell me how to turn on a led
