Hi Nilabh Anand,

I am currently working on the AM2634COLFHAZCZR custom board with
DP83869HM PHY bring-up, and I have installed the software packages from
the link below. 
https://www.ti.com/tool/download/MCU-PLUS-SDK-AM263X/08.05.00.24
After opening the Ethernet examples, I want to know which example is the simplest and most suitable for Ethernet bring-up.
My goal is only basic Ethernet bring-up.
I tested one of the examples, but it is not working on my custom board.
C:\ti\mcu_plus_sdk_am263x_08_05_00_24\examples\networking\lwip\enet_lwip_cpsw\am263x-cc\r5fss0-0_freertos
I need guidance on how to edit the example.syscfg file — specifically how to configure Ethernet and the PHY in the SysConfig file.
Please provide a step-by-step
process, including any changes required in the example code and how to
modify the project according to my custom board and PHY.
Could you please suggest this?

Sure,

Please refer to this for step by step guide to integrate a custom phy

Dear Nilabh Anand
Request you to please review the schematic and provide guidance for achieving stable Ethernet bring-up and reliable ping operation.

CUSTOM_BOARD-REV02.pdf

Hi team 

I would like guidance on:

1. Correct strap resistor configuration validation

2. RGMII timing and clock verification

3. PHY address and auto-negotiation configuration

4. Software configuration alignment with hardware schematic

5. Debug steps for achieving stable Ethernet ping

If possible, I would appreciate support through a short Microsoft Teams call where I can walk through:

• The schematic

• Strap resistor configuration

• PHY connections

• Software configuration

This would greatly help in resolving the bring-up issues efficiently.

could you please kindly resond on this 

Brennan Hartigan Could you please help with quick check of the schematics

we would greatly benefit from your guidance to ensure that our configuration and approach are aligned with best practices.

Would it be possible to arrange a Microsoft Teams call at your convenience to walk us through the recommended configuration steps for Ethernet bring-up using the SDK examples? A short session would help us clarify key points and avoid potential issues during implementation.

Please let us know your available time slots, and we will adjust accordingly.

phanendra beella the schematic looks fine at a high level, I would start a new thread with the PHY part number (DP83869) so this gets assigned to the Ethernet PHY team and they can review the schematic at the PHY device level.

Regards,

Brennan

Dear Brennan Hartigan,

Thank you for your response.

We require guidance on the recommended configuration settings in Code Composer Studio (CCS) to successfully bring up Ethernet on our custom board. We are currently using the SDK example projects to validate Ethernet functionality, including ping, internal loopback, and external loopback tests.

However, we would appreciate your support in confirming the correct configuration (CPSW, MDIO, RGMII, PHY, and lwIP settings) to ensure proper operation on our custom hardware.

Kindly provide the necessary recommendations and configuration details to help us proceed further.

Thank you for your support.

please kindly respond on this please

Hi Phanendra,

There are no specific changes needed in CCS for board bring up.

You need to follow the guide on the custom phy integration as I have shared before.

General ethernet debug guide:

https://dev.ti.com/tirex/explore/node?node=A__AaBu6ik6ZY8v2032wjLx6Q__AM26X-ACADEMY__t0CaxbG__LATEST

Please do understand that we cannot bring up board on your behalf, we will need the work done on your side, while we can offer the guidance on issues, if they are specific, general issues are captured in sdk documents.

Hi Anand,

Thank you for your reply.

After making the suggested configuration changes in SysConfig for the enet_lwip_cpsw_am263x_cc example, we are now able to see the logs on the UART console. Please find the attached screenshots of the logs for your reference.

However, we are currently unable to perform a dynamic ping to the board.

Could you please help us identify what additional configuration or steps might be required to enable dynamic ping successfully?

Thank you for your support.

From your logs I can see that IP address is not assigned, its 0.0.0.0, my suggestions would be to eitehr use a switch to get IP address or use static IP config

e2e.ti.com/.../faq-processor-sdk-am64x-configure-static-ip-with-mcu-sdk-enet_lwip_cpsw-or-enet_lwip_icssg-example

Hi Phanendra,

Since this is your custom board bring-up, my advice is to follow this flow:

1. Run the enet_loopback example: First PHY loopback, then MAC Loopback

https://software-dl.ti.com/mcu-plus-sdk/esd/AM263X/latest/exports/docs/api_guide_am263x/EXAMPLES_ENET_CPSW_LOOPBACK.html

PHY loopback will help make sure your PHY integration is fine

MAC loopback example will help make sure your MAC level Ethernet is working fine. It is expected that you see PHY link ups and MAC Port link ups similar to the logs in the above link.

Parallely, as recommended by Brennan. please start another thread specific to PHY strap settings and schematics which can be directly assigned to the PHY team for a quicker response.

2. Next, run an LWIP example with static IP forced (instead of DHCP), to be sure that the Lwip examples are working fine.

Follow the steps here to modify enet_lwip_cpsw example to force a static IP: https://software-dl.ti.com/mcu-plus-sdk/esd/AM263X/latest/exports/docs/api_guide_am263x/EXAMPLES_ENET_LWIP_CPSW.html#autotoc_md2921

Next, once static IP works, roll-back to DHCP auto IP (i recommend testing static IP first to be sure the Hardware is fine, directly testing DHCP adds more test variables and it is difficult to understand if issue is with AM26x or the test setup).

By default, the SDK has DHCP enabled and doesn't need any change, If DHCP doesn't work, it is most certainly an issue with the DHCP server/Switch/Link partner not assigning an IP address.

Also make sure the PHY address are correctly set in the Syscfg.

At any steps if you encounter errors, please see the CPSW stats and LWIP stats and follow the Ethernet debug guide here:
