Marvell AQR113 PHY, THOR

I’ve read in other posts about the MGBE not supporting 10G BASE-T PHYS over XFI/MDIO..

How does this exist then? Assuming one needs inside Nvidia engineering services to enable this PHY??

Thanks for any help.

You could look at that device’s BSP to see how they implemented it to see if that helps you. carrier-jetson-thor

Looking at the Jetson Thor L4T r38.4.0 Release Notes.pdf that’s next to their BSP tells how to apply the bsp to a 38.4 Linux_for_Tegra instance. So that points to whatever they do to implement that networking device to being in their bsp.

Curiosity, downloaded the bsp. Here’s just a quick look that you could expand to try and implement.

tar xf CTI-L4T-THOR-38.4.0-V004.tgz
cd CTI-L4T-THOR

<Linux_for_Tegra>/source/out/kernel/kernel-noble/scripts/extract-ikconfig kernel/Image > Image.config

grep -i aqu Image.config
