Hi Team,
I have successfully compiled and built DPDK on a Windows system and am using a custom driver in conjunction with DPDK. I am able to write to the registers, and the driver can also read from them. Additionally, I have successfully loaded the netuio driver onto my network interfaces (01:00.0 and 01:00.1).
However, when running the DPDK application, I encounter the following error: "Invalid memory, No probed Ethernet devices." The issue is detailed further in the screenshot below.

Could you please assist in identifying the cause of this error and advise on potential steps to resolve it?
Thank you in advance for your support.
Best regards,
Thenveer

This question is probably showing a lack of documentation.
Please can we have this gap solved with a patch?
