Part Number: AM4379

Tool/software: TI-RTOS

Hi folks,

I have the EtherCAT_Slave_full_AM437x_arm Demo running on my idk4379 board with a custom ESI-file.

I also have achieved to get the IO-LINK Master Demo running with hardware like TIDA-010016.

Now i want to combine Both of these Demos to have IO-Link Data on EtherCAT available running one Part on PRU0 and the other part on PRU1.

1. So which hardware changes on idkAM4379 i have to do to archieve this ?

2. Also how can i get both of these demos running one on PRU1 and other on PRU0 ?

3. How to intercommunicate  between these two PRU's    

thx in advance

  • Hi Haxor,  

    IO-link frame handler (PRU Firmware) runs on AM437x PRU-ICSS0. You can check this iniside IOLINK_soc.c (IOLINK_v0_SwAttrs iolinkInitCfg). On the other hand PRU-ICSS EtherCAT runs on PRU-ICSS1, so at least w.r.t to PRU-ICSS you should be good =)

    About how to intercommunication between PRU's, let me share with you a TI Design that shows a Profinet to Profibus gateway, so you can get some ideas concepts from there. http://www.ti.com/lit/ug/tiducu0/tiducu0.pdf

    Also, let me point you to another E2E with a similar question for some additional information:  https://e2e.ti.com/support/processors/f/791/t/814825

    thank you,

    Paula
