JESD204B - How to generate a custom pattern and repeat it

According to ug-1727 there is a "Pattern Generator" and written"There is also a way the user can load a custom pattern into the framer which can be verified on the baseband processor"

So, How can I set the pattern and run test data?

I'm using ADRV9026

    If you are testing on EVB and TES GUI setup, please use the attached iron python script to load custom patterns.

    After executing the script, capture the RX data and check whether the transmitted and receive patterns are matching.


  • Thank for your response!
    But we are not running with ADI's GUI, instead we use Xilinx FPGA and "ADRV9026 Released Software Package SW2.0.0.16

    In your script you set "FrmTestDataCfg=Types.adi_adrv9010_FrmTestDataCfg_t()" And i cant find:

    1. "Types" field in "adi_adrv9025_FrmTestDataCfg" structure

    2. "adi_adrv9010_FrmTestDataCfg_t" function doesn't exists

    Please refer to adi_adrv9025_FramerTestDataSet API from adi_adrv9025_data_interface.h file.

  • Thank for effort!

    Its exactly my problem, according to quoted by you code section, how can I set the field Type= "my custom pattern" ? "Type" field is not part of "adi_adrv9025_FrmTestDataCfg_t" structure

    In your python script you used with a statement "FrmTestDataCfg = Types.adi_adrv9010_FrmTestDataCfg_t()" ,
    and what's the equivalent to this in "ADRV9026 Released Software Package SW2.0.0.16

    my code is:

    adi_adrv9025_FrmTestDataCfg_t frmTestDataCfg;

    <here I should set my custom pattern> 
    frmTestDataCfg.framerSelMask = ADI_ADRV9025_FRAMER_0;
    frmTestDataCfg.testDataSource = ADI_ADRV9025_FTD_PATTERN_REPEAT;
    frmTestDataCfg.injectPoint = ADI_ADRV9025_FTD_SERIALIZER;

    <here I should set my custom pattern> 

    The custom pattern is set through the SPIWrites.

    ##### YOUR CODE GOES HERE #####
    #set the 16 bit user pattern
    #Test data to transmitted
    spiWrite(0x6e32, 0x55)
    spiWrite(0x6e33, 0x55) 

    In your python script you used with a statement "FrmTestDataCfg = Types.adi_adrv9010_FrmTestDataCfg_t()" , and what's the equivalent to this in "ADRV9026 Released Software Package SW2.0.0.16

    Please refer to the example code available in main.c file inside the API package. (Adi.Adrv9025.CustomerPkg_broad_market.\Adi.Adrv9025.Api\src_broad_market\c_src\app\example.main.c)

    You need to use something similar below for adi_adrv9025_FramerTestDataSet API.

    /* Setup internal Tx test tone frequency */
    adi_adrv9025_TxTestToneCfg_t toneCfg = { 0 };
    toneCfg.txChannelMask = ADI_ADRV9025_TXALL;
    toneCfg.txToneFreq_Hz = 500000;
    toneCfg.txToneGain = ADI_ADRV9025_TX_NCO_0_DB;
    toneCfg.enable = 1;

    recoveryAction = adi_adrv9025_TxTestToneSet(adrv9025Device, &toneCfg, 1);
    if (recoveryAction != ADI_COMMON_ACT_NO_ACTION)
    printf("Failed to setup ADRV9025 Tx Test Tone\n");
    printf("ERROR: Error number %d, Recovery action %d. In file %s, in function %s, in line %d, variable name %s. Error message %s.\n",
    /* Call action handler */
