2017.1-2018.3 Zynq UltraScale+ MPSoC: Linux MACB MDIO support for single MAC managing multiple PHYs


How can I enable MDIO support for a single MAC managing multiple PHYs?


You will need to download and apply the patch attached to this answer record with the same release version as the software you are using.

The patch should be applied to <plnx-proj-root>/project-spec/meta-user/recipes-kernel/linux/linux-xlnx_%.bbappend

  • The 2017.3 patches can be used for the 2017.4 release
  • The 2018.2 patch can be used for the 2018.1 release
  • A patch for 2018.3 has now been added
An example MACB device tree snippet can be found on GitHub:

Note: To apply a patch to recipes, please refer to (UG1144) or http://www.wiki.xilinx.com/PetaLinux+Yocto+Tips
