    Hi, 

    Apologies for the delayed response as previously our embedded team did not monitor this forum category for embedded related question until we are notified by other teams .

    As for this issue, I saw there is a requirement that any transaction cannot cross a 4KB boundary in the AXI protocol document (https://developer.arm.com/documentation/ihi0022/latest/) . Is your transaction adheres to this requirement?

    Perhaps you can refer to this demo example

    Thanks

    Regards
