    hello i need to disable TX_QEC_init i dont understand how to do it?
    

    in ug-992 Rev. B | Page 73 i see TX_QEC_INIT it turns out it is disabled by default in git repo r2019_2?
    

    uint32_t initCalMask = TX_BB_FILTER | ADC_TUNER | TIA_3DB_CORNER | DC_OFFSET | TX_ATTENUATION_DELAY | RX_GAIN_DELAY | FLASH_CAL | PATH_DELAY | TX_LO_LEAKAGE_INTERNAL | TX_QEC_INIT | LOOPBACK_RX_LO_DELAY | LOOPBACK_RX_RX_QEC_INIT | RX_LO_DELAY | RX_QEC_INIT;

      Hi,
      

      TX_QEC_INIT is always run by default.
      

      You need to modify the source code if you need to skip it.
      

      When using the jesd204-fsm implementation, these is the place where you need to clear the flag from the mask. 
      

      https://github.com/analogdevicesinc/linux/blob/master/drivers/iio/adc/adrv9009.c#L6563
      

      In case you still use the old/deprecated mode, you need to modify the mask here: 
      

      https://github.com/analogdevicesinc/linux/blob/master/drivers/iio/adc/adrv9009.c#L529

        Are you using the jesd204-fsm devicetree?
        

        Can you print the calibration mask before calling ad9371_init_cal() ?
