FMCDAQ2 AD9144 ILA error


I am using the AD9144 of FMCDAQ2. I have configured the map register of AD9523-1 and AD9144 through SPI. Successfully produced refclk and sysref.
However, an ILA error occurred during the configuration of the AD9144. I use mode 4 single link mode according to the AD9144 manual.

After reading the 470-473 register, ILA failed many times, although it was successful a few times.

I tried to modify the map register of the ILA, but it didn't work.
I don't know where the mismatch is. Please tell me where the problem is.

    Can you share the values of the registers  ? 

    Are you sing linux or no-os ?

    What version of source and tools are you using? 

    Please give more details on what do you mean by "ILA error".



  • I use the SPI protocol to configure the AD9144 register, the value is as follows.I am using windows system, not linux or no-OS. The version of Vivado is 18.2.

    The value of the 0x023 is 14, and the value of 0x281 is 0B.
    The value of 0x470 may be any value from 01-0F, the value of 0x471 may be 00 or 0F, and the values of 0x472 and 0x473 are generally 00.
    But sometimes the values of 0x470-473 are all 0F, and JTX and JRX match successfully. I don’t know what exactly caused these values to change.

    The sync, sysref, and refclk signals of AD9144 are shown in the figure
