Segmentation fault on GPO example

[myso]

Hello,

I am running tha example code on RPi 5 on Ubuntu. Everything compiles fine but I get a Segmentation fault. I did configure the hwconfig.h

I added some debug messages to the code:

int main (void)
{
  const ST25DV_PASSWD st25dv_i2c_password = {.MsbPasswd = 0, .LsbPasswd=0};	

  /* Init of the Type Tag 5 component (ST25DV-I2C) */
   (BSP_NFCTAG_Init(0) != NFCTAG_OK);
  printf("ST25DV-I2C init done\r\n");
printf("DEBUG1\n");
  /* Present configuration password */
  BSP_NFCTAG_PresentI2CPassword(0, st25dv_i2c_password );
printf("DEBUG1.5\n");
  /* Set GPO Configuration */
  BSP_NFCTAG_ConfigIT(0,ST25DV_GPO_ENABLE_MASK | ST25DV_GPO_FIELDCHANGE_MASK );
 	
printf("DEBUG2\n");
  while(ST25DV_GPO_Init() != NFCTAG_OK);
  printf("GPO init done\r\n");

This is where it crashes:

./st25dv-i2c_gpo 
ST25DV-I2C init done
DEBUG1
DEBUG1.5
Segmentation fault (core dumped)

 Any help will be appreciated.

Hi,

Line 6 of the code snippet: the code does not check the return code of BSP_NFCTAG_Init(0). If the BSP_NFCTAG_Init(0) fails, some internal function pointers may be not initialized.

Make sure to test each return code in particular the return code of BSP_NFCTAG_Init.
