How report a bug in ST25DVxxKC driver?

[Tomáš Juřena]

Hello, I am working on a project that integrates the ST25DV64KC NFC chip and I think that there is a bug in ST25DVxxKC_ReadMemSize function. I added the driver from the STM32CubeMX X-CUBE-NFC7 pack. I also found a GitHub repository with this pack but it is empty. How can I report a bug?

The mentioned function should compute the size of the EEPROM memory but the condition on line 1252 fails, so the size is not computed and the NFCTAG_OK is returned. When the inequality operator is inverted the function works as expected.

Can you point me to the bug tracker or the correct repository?

Thanks.

Best regards,

Tomas

Hi @Tom�? Ju?ena​,

Thank you to report this bug, there is no external bug tracker for you to report it. You did the correct way by asking in the forum. I will create an internal ticket to report it.

Please find the fix here after

/**
  * @brief  Reads the ST25DVxxKC Memory Size.
  * @param[in] pObj pointer to the device structure object.
  * @param[out] pSizeInfo Pointer on a ST25DVxxKC_MEM_SIZE structure used to return the Memory size information.
  * @return int32_t enum status.
  */
int32_t ST25DVxxKC_ReadMemSize(const ST25DVxxKC_Object_t *const pObj, ST25DVxxKC_MEM_SIZE_t *const pSizeInfo)
{
  uint8_t memsize_msb;
  uint8_t memsize_lsb;
  int32_t status;
  
  pSizeInfo->Mem_Size = 0;
 
  /* Read actual value of MEM_SIZE register */
  status = ST25DVxxKC_GetMEM_SIZE_LSB(&(pObj->Ctx), &memsize_lsb);
  if(status == NFCTAG_OK)
  {
    status = ST25DVxxKC_GetMEM_SIZE_MSB(&(pObj->Ctx), &memsize_msb);
    if(status == NFCTAG_OK)
    {
      status = ST25DVxxKC_GetBLK_SIZE(&(pObj->Ctx), &(pSizeInfo->BlockSize));
      if(status == NFCTAG_OK)
      {
        /* Extract Memory information */
        pSizeInfo->Mem_Size = memsize_msb;
        pSizeInfo->Mem_Size = (pSizeInfo->Mem_Size << 8) |memsize_lsb;
      }
    }
  }
  return status;
}

Kind Regards.
