[srslte-users] Crash when using ./pdsch_enodeb -x diversity or cdd

[Jayesh PATEL]

Hi All,

 

I am trying to use srsLTE as enodeb transmitter in diversity or CDD mode and
It crashes always at same point. I have built srsLTE normally without any
flags.

 

I am using following command.

 

./pdsch_enodeb -f 1842500000 -c 1 -x diversity/cdd

 

 

Crashing at :  

lib/src/phy/mimo/precoding.c:1960

int srslte_precoding_cdd_2x2_gen(cf_t *x[SRSLTE_MAX_LAYERS], cf_t
*y[SRSLTE_MAX_PORTS], int nof_symbols, float scaling)

{

  scaling /= 2.0f;

  for (int i = 0; i < nof_symbols; i++) {

    y[0][i] =  (x[0][i]+x[1][i]) * scaling;

    y[1][i] =  (x[0][i]-x[1][i]) * scaling;

    i++;

    y[0][i] =  (x[0][i]+x[1][i]) * scaling;

    y[1][i] = (-x[0][i]+x[1][i]) * scaling;

  }

  return 2 * nof_symbols;

}

 

Do you know what could be the issue  or is this known issue ??  crash logs
and objdump attached here attached here.

 

 

Regards

Jayesh PATEL
