LP-AM243: Ethernet examples in SDK

Koichiro Tashiro
Mastermind 22915 points
Part Number: LP-AM243
Other Parts Discussed in Thread: DP83869

Hi,

My customer is evaluating UDP operation using SDK sample (enet_cpsw_udpserver_am243x-lp_r5fss0-0_freertos_ti-arm-clang).
HW : LP-AM243 PROC109E3
SW : MCU PLUS SDK Version: 08.05.00.24

Q1) The example uses polling in RX task.
To improve performance, the customer wants to use an interrupt.
Is there an example using an interrupt?

Q2) Is 10Mbps operation supported?
The customer configure an external device as 10Mbps and LP-AM243 can link-up with it by auto-negotiation.
But it does not seem to communicate with 10Mbps.

Thanks and regards,
Koichiro Tashiro

    We can provide guide on how to do it. Another stand alone example will not be possible. Customer can follow : https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/EXAMPLES_ENET_LAYER2_CPSW.htm this example.

    The exact code to refer is located at examples\networking\enet_layer2_cpsw\V0\l2_cpsw_dataflow.c

    10 Mbps mode is supported both on CPSW and the dp83869 phy. I will check internally if it is tested. Can you please ask customer to get the debug statistics using :(+) [FAQ] MCU-PLUS-SDK-AM243X: How do I get CPSW diagnostic statistics using debug gels in MCU+ SDK Enet LLD? - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E support forums

    also please ask customer to share the application uart log.

    Hi Nilabh,

    Sorry for the delay, I got below feedback from the customer.

    Q1 is now closed. The customer confirm the interrupt operation. Thanks!

    For Q2, please find below uart log.
    AM243x is UDP Master. An external device (Hub) is 10-base fixed.

    Hi Koichiro Tashiro,
      Sorry for the late response!

    About Q2, need more information to confirm the phy setting.

    Want to check the speed and duplexity that is negotiated after auto negotiation is completed.
    Can you pls share the values of below six variables taken from "Expressions" tab in CCS.

    ((Cpsw_Handle)('ti_enet_open_close.c'::gEnetAppSysCfgObj.hEnet->enetPer))->hPhy[0]
    ((Cpsw_Handle)('ti_enet_open_close.c'::gEnetAppSysCfgObj.hEnet->enetPer))->hPhy[0]->addr
    ((Cpsw_Handle)('ti_enet_open_close.c'::gEnetAppSysCfgObj.hEnet->enetPer))->hPhy[0]->state.speed
    ((Cpsw_Handle)('ti_enet_open_close.c'::gEnetAppSysCfgObj.hEnet->enetPer))->hPhy[0]->state.duplexity

    ((Cpsw_Handle)('ti_enet_open_close.c'::gEnetAppSysCfgObj.hEnet->enetPer))->hPhy[1]
    ((Cpsw_Handle)('ti_enet_open_close.c'::gEnetAppSysCfgObj.hEnet->enetPer))->hPhy[1]->addr
    ((Cpsw_Handle)('ti_enet_open_close.c'::gEnetAppSysCfgObj.hEnet->enetPer))->hPhy[1]->state.speed
    ((Cpsw_Handle)('ti_enet_open_close.c'::gEnetAppSysCfgObj.hEnet->enetPer))->hPhy[1]->state.duplexity

    Make sure to captured the values of above variables only after link is UP.

    Thanks in advance!

    With regards,
    Pradeep
