What is the return value of the error flag?

Hi

We will get back to you.

Hi,

The error happens when ADRV9001 is calibrating and the signal is applied to the RX port, we recommended no signal has to be applied on the RX port as you can see from the below image

Hi,

    We are not using the signal generator, It is the closed one, we are using the code generated by the TES after init we are calibrating and here I've added the print to get the error flag . In this case what is the reason that its returning the errorflag "7" and this is the rare case as I said earlier it was happening one in thousand. Is there any api to verify something like RF PLL lock or anything to verify this and how to recreate this error and to resolve the same . 

int calibrate(adi_adrv9001_Device_t * adrv9001Device_0)
{
int32_t error_code = 0;
adi_adrv9001_InitCals_t initCals_1 = {
.sysInitCalMask = (adi_adrv9001_InitCalibrations_e) 0,
.chanInitCalMask = { ADI_ADRV9001_INIT_CAL_TX_QEC | ADI_ADRV9001_INIT_CAL_TX_LO_LEAKAGE | ADI_ADRV9001_INIT_CAL_TX_LB_PD | ADI_ADRV9001_INIT_CAL_TX_BBAF | ADI_ADRV9001_INIT_CAL_TX_BBAF_GD | ADI_ADRV9001_INIT_CAL_TX_ATTEN_DELAY | ADI_ADRV9001_INIT_CAL_TX_DAC | ADI_ADRV9001_INIT_CAL_TX_PATH_DELAY | ADI_ADRV9001_INIT_CAL_RX_HPADC_FLASH | ADI_ADRV9001_INIT_CAL_RX_LPADC | ADI_ADRV9001_INIT_CAL_RX_TIA_CUTOFF | ADI_ADRV9001_INIT_CAL_RX_GROUP_DELAY | ADI_ADRV9001_INIT_CAL_RX_QEC_TCAL | ADI_ADRV9001_INIT_CAL_RX_QEC_FIC | ADI_ADRV9001_INIT_CAL_RX_RF_DC_OFFSET | ADI_ADRV9001_INIT_CAL_RX_GAIN_PATH_DELAY, (adi_adrv9001_InitCalibrations_e) 0 },
.calMode = ADI_ADRV9001_INIT_CAL_MODE_ALL,
.force = false};
uint8_t errorFlag_1 = 0;

error_code = adi_adrv9001_cals_InitCals_Run(adrv9001Device_0, &initCals_1, 300000, &errorFlag_1);
printf("The value of Error flag is %d \n",errorFlag_1);
AUTOGENERATOR_ERROR_HANDLER(error_code);

Hi,

Yes, there are API for checking the pre and post calibration checks, you can find this information under the chapter 'SYSTEM INITIALIZATION AND SHUTDOWN' the latest user guide (https://www.analog.com/media/en/technical-documentation/user-guides/adrv9001-ug1828.pdf )

we are disabling the signal transmission before calibration using gpio configuration and enabling after the calibration  

key=$1
if [[ "$key" == "1" ]]; then
echo out > /sys/class/gpio/gpio398/direction
echo 0 > /sys/class/gpio/gpio398/value
echo "Enabled RF_BUF_0"
elif [[ "$key" == "0" ]]; then
echo in > /sys/class/gpio/gpio398/direction
sleep 1
echo 1 > /sys/class/gpio/gpio398/value
cat /sys/class/gpio/gpio398/value
echo "Disabled RF_BUF_0"
else
echo "Please provide a valid input!"

In this case how to recreate the same issue as its happening in a random manner as 1in 1000 so is there any way to recreate the same

Hi,

Can you tell us if you are using the ADI provided platform or its a custom platform? Also can you provide us the taxidi file with the issue replicated in the ADI provided platform? with the information provided above we wont be able to debug it. 

Regards,

Rahul  

Hi, 

   I'm using the adi provided platform.drive.google.com/.../view this is my taxidi file

Hi,

Could you please provide the taxidi file here? 

Regards

Rahul 

I cant attch the .taxidi file here

Hi Rahul,

    Is there any update...

Regards,

Ram
