PROCESSOR-SDK-AM64X: Problems with setting up ENET_SWITCH example

Hello Jonas Knüpper,

The engineer who works on the Networking side was on leave, and responses were getting delayed.

Hi,

Thanks for your query.

Looks like related to below thread. 

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1216936/faq-processor-sdk-am64x-enet-layer-2-cpsw-example-not-working-on-am64x-mcu-sdk-08-05-00-24

Let me know if you need further help.

Hi Ashwani,

Thanks for your response.

I followed the suggested steps but the problem still persists. Port1 and Link1 goes up, but there is no output for Port2 and Link2.

In the UART Output from above it can be seen, that there is a "EnetPhy_bindDriver" Output after opening port 1, but not after port 2. Maybe its an configuration error for the second PHY?

Hi Jonas,

Will it be possible for you,

1. To try to reproduce the issue on AM64x-EVM with latest MCUSDK release (8.6) ?

If not,

1. To try to reproduce the issue on AM64x-SK with latest MCUSDK release (8.6) ?

Meanwhile I will try to reproduce the issue on AM64x-SK board with latest MCUSDK release (8.6).

Are you okay with this ?

Best Regards

Ashwani

Hi Ashwani,

thanks a lot for your help. I tried to reproduce the issue with MCUSDK Version 8.6.0.43 but the problem still persists. I followed the steps from the linked thread and also included the project in ccs via resource explorer and started a debug session with the same result.

If needed, here are the bootloader versions:

DMSC Firmware Version 8.5.3--v08.05.03 (Chill Capybar
DMSC Firmware revision 0x8
DMSC ABI revision 3.1

Unfortunately we dont have a AM64x-EVM at our institute, just the AM64x-SK-B board. Is there a migration needed, since it is a hs-fs device?

If it makes things easier, we can probaply arrange a call via mail?

Thanks in Advance

Jonas

Thanks for update.

Please confirm the setup as below:

• AM64x-sk board with SDK 8.6 release.
• example will be used: CPSW switch example "C:\mcu_plus_sdk\examples\networking\enet_layer2_cpsw_switch\am64x-sk"

If possible, can you please share the picture of your setup to make similar setup on my side ?

Best Regards

Ashwani

Hi Ashwani,

here is the screenshot you asked for.

Board is SK-AM64B.

CCS Version is 12.3.0.00005.

Syscfg Version is 1.14.0

CPSW-Port is connected to Ethernet-Adapter of my PC (PHY0).

Second Port is connected to Ethernet-Adapter of the docking station (PHY1).

Hope that helps.

Best regards

Jonas

Thanks Jonas for setup details.

It will be easy if you can share picture of these connections in your setup.

Can you try with CPSW_port1 <=> LAN_Cable <=> CPSW_port2 ?

Best Regards

Ashwani

Hi Ashwani,

here is the picture:

red cable is connected to host-PC and CPSW-RGMII-1

yellow cable is connected to docking-station of host-PC and CPSW-RGMII-2

- Tried the cable between the two cpsw ports but with no other results

In my AM64x.ccxml Console i have the output, that "DDR is not initialized with R5 connect"

but Initialization Script "AM64_DDR_Initialization_ECC_Disabled" hangs with output "Waiting for first frequency change request ..."

Best Regards

Jonas

Hi Jonas,

Thanks for setup picture.

Means loopback setup for CPSW is also not working. I will try this first on my setup.

This may be related to ccxml file limitation to initialize DDR.

Can you please try "Flash SOC Initialization Binary" method mentioned in https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/latest/exports/docs/api_guide_am64x/EVM_SETUP_PAGE.html

Best Regards

Hi,

thanks for retrying.

Flash initialization may be a problem of ccs, as i found out in an other thread. Bootloader output in OSPI mode looks good.

Another interesting thing:

In autogenerated "ti_board_config.c" there are some irritating things:

The ".phyAddr" of second entry in "gEnetCpbBoard_am64x_evm_EthPort[]" is 3 instead of 1. I cannot change the phyAdress in Sysconfig-Tool because its readonly. Where can i change this?

The ".extendedCfg" of second entry points to "gEnetCpbBpard_dp83869PhyCfg", what irritates me. Because the documentation said, that SK-AM64B comes with two DP83867 transceivers. 

Here is the part of "ti_board_config.c"

/*

 *

        .phyCfg   =

            .phyAddr = ENETPHY_INVALID_PHYADDR,
        },
        .flags    = 0U,
    },
};

Ho can i edit those parameters? Because the file is autogenerated with every built. Is there any config file for the board configuration which is used in Sysconfig Tool?

Best Regards,
Jonas
