DPDK 25.11 on Verdin iMX95

Technical Support

Hi,

since DPDK 25.11 the ENETC4 driver for iMX95 is supported, see also 20. ENETC4 Poll Mode Driver — Data Plane Development Kit 25.11.0 documentation

I tried installing it on my Verdin iMX95 BSP7.4, but I ran into an issue where the link status is always reported as down. I tested this using dpdk-testpmd. Has anyone successfully gotten DPDK ENETC4 running?

The documentation above mentions that “NXP’s Linux Factory releases” are required as a prerequisite. Is BSP 7.4 based on NXP Linux LF?

Thanks,

Holger

DPDK ENETC4 Support on Verdin iMX95

I understand you’re experiencing link status issues with DPDK 25.11’s ENETC4 driver on your Verdin iMX95 with BSP 7.4.

Current DPDK Support Status

Based on the available documentation, there’s a discussion in the community about DPDK support for iMX95(1). The i.MX Linux Reference Manual mentions support for DPDK version 22.11, and it appears that special branches rather than official DPDK sources are being used(1).

BSP 7.4 and NXP Linux Factory

To answer your question about BSP 7.4 being based on NXP Linux LF - I’d need to gather more specific information about your setup to provide accurate guidance. Could you run the tdx-info command on your device and share the output? This will help identify the exact BSP version and underlying Linux kernel details. You can find more information about this command at https://developer.toradex.com/software/development-resources/tdx-info/.

DPDK Testing Experience

The available sources show DPDK testing examples on other Toradex platforms like the Verdin iMX8M Mini(2), where specific device tree modifications were required to adapt the standard Linux FEC kernel driver to DPDK PMD driver compatibility.

Next Steps

Since the iMX95 is an early access product, there may be specific considerations for DPDK ENETC4 driver support. The link status issue you’re experiencing could be related to:

  1. Device tree configuration requirements
  2. Driver initialization sequences
  3. Hardware abstraction layer compatibility

For the most accurate guidance on DPDK 25.11 ENETC4 support with your specific BSP version, I’d recommend providing the tdx-info output so we can better understand your platform configuration.
