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.
[cid:94365efe-78e5-4ef2-9d9a-b49188e35759] 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 ________________________________ From: Thomas Monjalon <[email protected]> Sent: Wednesday, November 5, 2025 3:55 PM To: [email protected] <[email protected]>; Dmitry Kozlyuk <[email protected]> Cc: Thenveer Poolakkanni <[email protected]>; [email protected] <[email protected]>; Chaturbhuja Nath Prabhu <[email protected]>; Ayshathul Thuhara <[email protected]> Subject: Re: Assistance with DPDK on Windows 05/11/2025 08:36, Dmitry Kozlyuk: > Hi Thenveer, > > > On 11/5/25 10:18, Thenveer Poolakkanni wrote: > > 1.

Please can we have this gap solved with a patch?
