AM5748: Ethernet through PRU

Janardan M

Part Number: AM5748

HI ,

I am working on AM574x processor sitting on our custom board, I am trying to establish Ethernet communication through PRU-ICSS, I followed the below link ,

processors.wiki.ti.com/.../PRU-ICSS_Ethernet

I am unable the see the PRU ethernet ports when i use " ifup eth2" and "ifconfig",

I looked into the prueth.c driver and added some prints and tried to trace the issue, it is failing to connect to phy with following error message.

couldn't connect to phy /ocp/pruss_soc_bus@4b2a6004/pruss@0/mdio@32400/ethernet-phy@0

This is caused inside the function "prueth_netdev_init".

I am finding difficulty to understand the entire mechanism.

Is the "prueth.c" driver trying to connect to external Phy or what is it trying to do at this point?

From my initial ground work I assumed that "am57xx-pru0-prueth-fw.elf" is loaded through remoteproc, once this firmware starts executing the PRU Ethernet would be established.

But, now I am observing that prior to loading the firmware to PRU , error message is popping up as "couldn't connect to phy" from "prueth_probe" function itself.

I feel that my understanding of entire process is going wrong. Somebody please provide me an insight view of whats happening and how to resolve the issue.

Also, Where is the point where configurations is being written to external PHY through MDIO lines with reference to PRU ethernet.

Thanks,

Janardan

Hi,

Which SDK are you using? Also could you please attach your boot log?

The DTS file provides information to the kernel on which MDIO bus and what the address is of the PHY. By looking at the boot log if you do not see the PHY being identified as the kernel initializes the PRU eth interface will not be able to come up. If you do a ifconfig -a and the interface is not listed this could be one reason why.

Best Regards,
Schuyler

I hit reply too quick, could you also please attach the relevant portion of your board DTS file showing the PRU and MDIO nodes? Since this is a custom board is u-boot configured pin mux wise for these interfaces?

Again, Best Regards,
Schuyler

Hi Schuyler,

Let me elaborate what exactly we are trying to do.

Please find the attached image for the connection details,

In our present scheme, AM5748 PRU-ICSS unit is used in MII mode and there is a ARM9 based processor from some other vendor configured to work in rev MII / PHY mode (No PHY IC in middle)

Please find the below PinMux details.

Below is the section of DTS file.

        pruss1: pruss@0 {
                status = "okay";
        };
};

&pruss_soc_bus2 {
        status = "okay";

        pruss2: pruss@0 {
                status = "okay";
        };
};

&pruss2_mdio {
        status = "okay";
        pruss2_eth0_phy: ethernet-phy@0 {
                reg = <0>;
                interrupt-parent = <&gpio3>;
                interrupts = <30 IRQ_TYPE_EDGE_FALLING>;
        };

        pruss2_eth1_phy: ethernet-phy@1 {
                reg = <1>;
                interrupt-parent = <&gpio3>;
                interrupts = <31 IRQ_TYPE_EDGE_FALLING>;
        };
};

I have the following queries,

1) AM5748 PRU ICSS MII mode directly connected to ARM9 based processor working in reverse MII/PHY mode, is this kind of configuration possible?

2) Is my pin-mux and DTS configurations proper?

3) We are using Linux SDK version 5.0, in AM574x IDK board PRU-ICSS is connected to TLK10x PHY, can you please let me know in which file is configurations written to TLK10x PHY so that I can alter this section to write the configurations to ARM 9 working in Reverse MII/PHY mode?

Thanks,

Hi Janardan,

Thank you for the block diagram and DTS snippet.

Unfortunately TI is only able to support use-case questions related to connecting directly to a PHY. Since this is a MAC to MAC connection TI will not be able to support this query.

Best Regards,
Schuyler
