PLSDK-2583 is the internal ticket ID of the requirement that added the ICSS ethernet support in the first place. It is an internal ticket and does not have equivalent external ticket for itself.

Can you let me know what information you are looking for?

Hi Tanmay,

May I ask how I can configure Pruss to have 2 phys for Ethernet communication under Linux? In other words, how can I configure the Linux Pruss driver so that the ifconfig command can see 2 Pruss Ethernet device nodes?

Hi Tanmay,

I haven't used any versions before SDK8.2.1, maybe SDK8.2  has two Pruss phys configured by default, and prueth_core. c is also included in SDK8.2.1. But I am currently using SDK 9.2, but some of the files mentioned in the accompanying Doc are not included in SDK 9.2. Moreover, the default configuration of the SDK 9.2 device tree is two CPSW phy, as can be seen from the ifconfig and ethtool commands below:

I only found ti,icssg prueth. yaml in the Documentation/devicetree/bindings/net/directory of SDK9.2, and the content inside is not applicable to the device tree configuration of SDK9.2

In short, May i how to configure the device tree and .config of SDK9.2 so that I can see two pruss phys through ifconfig?

This won't be possible with SDK 9.2 as the support for PRUSS ethernet is descoped in this SDK.

If you would like to work with PRUSS ethernet, you will have to use SDK 8.2.1 or earlier.

Hi Tanmay,

I didn't understand what you meant. Did you mean that SDK 9.2 doesn't have a Linux pruss driver? Or SDK 9.2 support configuring the Pruss driver, but there is no guidance document available.
