PROCESSOR-SDK-AM64X: PRP setup with AM64x

Himansu Sethi

I am testing PRP with custom-designed AM64x boards. My setup looks something like the image below.

To create LAN1 and LAN2 we have used 2 PCs which will act as 2 Networks. Please suggest how do we need to configure these 2 PCs for testing PRP?

Note: These PCs do not have HSR/PRP capability.

Are you using Linux or freeRTOS? The instructions to setup PRP on AM64x Linux are at https://software-dl.ti.com/processor-sdk-linux-rt/esd/AM64X/latest/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Network/HSR_PRP.html?highlight=prp . This will work on any two ethernet devices. If you are using RTOS see https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/latest/exports/docs/api_guide_am64x/EXAMPLES_INDUSTRIAL_COMMS_PRP_DEMOS.html for an ICSS based Ethernet demo.

I'm not completely clear what do you mean with using a PC to act as a network. PRP is based on two completely independent LANs (A/red nd B/blue in your diagram), and a networking stack that is connected to both. So to have a PC participate you will need a PC with 2 network interface cards (NICs) to have the PC participate in the PRP network. The same commands that work on AM64x Linux will work on a Linux PC.
