Hi,


Is it possible to test with simple design with only the remote IP and see if you still see this issue or not? Also for this statement, "when using the 25us reset, the result of reading Reconfiguration Trigger Conditions parameter is incorrect.", may i know which parameter you are referring to?

    I can try what you suggest, will let you know when I got the results.

    I'm talking about this:

    Reconfiguration Trigger Conditions from ALTREMOTE IP

    • Bit 4—wdtimer_source: User watchdog timer timeout.
    • Bit 3—nconfig_source: External configuration reset (nCONFIG) assertion.
    • Bit 2—runconfig_source: Configuration reset triggered from logic array.
    • Bit 1—nstatus_source: nSTATUS asserted by an external device as the result of an error.
    • Bit 0—crcerror_source: CRC error during application configuration.

    The POR value for all bits are 0.

    All those bits are set to 1 if I don't reset the IP long enough. For a 500ms reset, it works fine.
