Below is the code that generates the ASSERT:

int mcard_write_bmask(mcard_t *card)
{
  CYG_CHECK_DATA_PTR(card, "valid card pointer required");
  CYG_CHECK_DATA_PTR(card->bmask, "valid mask pointer required");
  CYG_ASSERT(card->mcard_hdl,"Valid card handler required");

  if( !card->mcard_hdl ) return -EINVAL;
  if( !card->bmask ) return -EINVAL;

  int e;
  e = mcard_verify_card(card);
  if( e ) return e;

  e = cyg_io_set_config(card->mcard_hdl,CYG_IO_SET_CONFIG_CARD_LOCK,0,0);
  if( e ) return -EIO;

  cyg_uint32 address = card->header.bmask_offset;
   cyg_uint32 len = sizeof(cyg_uint32);
   
cyg_io_set_config(card->mcard_hdl,CYG_IO_SET_CONFIG_CARD_WRITE_POS,&address,&len);
   len = card->header.bmask_size;

   e = cyg_io_write(card->mcard_hdl,card->bmask,&len);
  
  cyg_io_set_config(card->mcard_hdl,CYG_IO_SET_CONFIG_CARD_UNLOCK,0,0);

  if( e ) return -EIO;

  return ENOERR;
}

**************************

and the mcard_write_bmask function is called from function below:

typedef struct mcard_t
{
  cyg_io_handle_t   mcard_hdl;
  mcard_header_t    header;
  mcard_bmask_t    *bmask;
  cyg_uint8         opened;
} mcard_t;

int I::formatCard()
{
  int e;

  mcard_t mcard;
  mcard.mcard_hdl = 0;
  e = mcard_open(&mcard);
  if( e ) return -1;

  MCARD_PRINT_HEADER(&mcard.header);

  CLEAR_BUF(mcard.bmask,mcard.header.bmask_size);
  e = mcard_write_bmask(&mcard);
  if( e ) return e;

  MCARD_PRINT_BMASK(&mcard);

  mcard_pdata_t pdata;
  CLEAR_BUF(&pdata,sizeof(mcard_pdata_t))
  e = mcard_write_pdata(&mcard, &pdata);
  if( e ) return e;

  MCARD_PRINT_PDATA(&pdata);

  return 0;
}
