Hi @allen18,

I was able to run the DMA test for over 50,000 iterations in my environment without encountering any DMA timeout issues, as shown in the attachment. The operating system used is CentOS 7. The software drivers generated from the design examples in both QPP v22.3 and v24.2 (the latest version) were tested and did not run into errors when performing the DMA test in an infinite loop.

May I ask which operating system you are using in your environment? Please ensure that it meets the requirements specified in the user guide, as the driver has been tested and verified with the OS.

Thanks.

Best Regards,

Ven

    These are my system information，perhaps environmental differences are causing these kinds of issues ?
