DRA821U: Issues with the QuadPhy on the J7200-EVM

Fabian

Part Number: DRA821U

Tool/software:

Hello,

this is a follow-up to the following thread:
DRA821U: How to map multiple MAC-only ports to A72 in ethfw with current SDK - Processors forum - Processors - TI E2E support forums

I still have issues getting the QuadPhy on the J7200-EVM to work properly. After receiving the patches, I did a fresh build with the newest Linux SDK and the ethfw. I also deactivated gPTP and changed the MAC address as suggested in the mentioned thread. The port configuration is unaltered, so no additional MAC-only port(s).

I can ping all the static IPs (assigned to eth0, eth1 and eth2) through the CPSW2G port, but there's no response when connecting to any of the MAC ports on the CPSW5G.

There seems to be an error message "EnetPhy_findCommonNwayCaps: PHY 1x: no common caps found". What could be the cause of this?

What else could I do to get it to work?

Thanks in advance!

It will be during the PHY reset and negotiation process, the PHY state machine prints no common Nway Caps.

I could see MAC Port-4 is linked up with 1Gbps.
CpswMacPort_checkSgmiiStatus: MAC 4: SGMII link parter config port: link up: 1-Gbps Full-Duplex
Cpsw_handleLinkUp: Port 4: Link up: 1-Gbps Full-Duplex

By default, MAC Port-4 is mapped to the RTOS client as a MAC-only Port. Only the MCU2_1 client can communicate over MAC Port-4.

To communicate with eth1, ensure Link up from MAC Port-2/3; similarly, to communicate with eth2, ensure Link up from MAC Port-1.

Best Regards,
Sudheer

Hi,

thanks for the info!

As for the log, I tried all kind of different permutations (pinging all the different eth interfaces from various MAC Ports), but it worked with none. On the other hand, I tried the Native Linux driver and all the MAC Ports worked out-of-the-box.

The ETHFW application out-of-box TI SDK should work with the default port mapping.

I could see the above IP registration with 192.168.100.171, from the Linux virtual switch port interface.

Can you please confirm, you have made any changes to the ETHFW application?

Please check once with the default TI configuration.

Also, ensure the native Linux driver enables overlay is not applied when ETHFW is mapped to the MCU2_0 core.

Sudheer

I installed PROCESSOR-SDK-LINUX-RT-J7200 with the most recent version 10.01.08.01 and loaded the pre-built binaries on an SD card. No changes were made. I assigned static IPs to the interfaces via Linux command line (e.g. 192.168.100.171), but could not get any ping.

As a next step. I sourced the Yocto environment and built an image from the SDK with the patches applied (see other thread; also for the ethfw, of course). I also deactivated gPTP and changed the MAC address, as suggested in the other thread. WIth that image, I also could not get any ping.

The overlay is not applied.

I'm pretty sure that I can rule out my hardware setup as a problem, because I can ping all ethernet interfaces through the MAC port on the CPSW2G.

Hi,

I have tested on my side using TI SDK as is with the default configuration.
The SDK used to test the ETHFW client networking is as captured below.

Connected the Test PC network cable to EVM via CPSW Port-2 (Switch port interface). Please find the ping log from the virtual switch port interface (eth1) to the test PC below.

The default port mapping of QSGMII is as follows.
https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j784s4/latest/exports/docs/ethfw/docs/user_guide/ethfw_c_ug_top.html#ethfw_depend_evm_quadport_j7200

Tested MAC Port-1, via virtual MAC only port interface on Linux to test PC. Please refer to the ping log below.

Best Regards,
Sudheer
