TMDS243EVM: How to add a Internet configure in Sysconfig based on INDUSTRIAL COMMUNICATION SDK?

Hi Hongkai,

Hi Aaeon,

I want to use both Internet and EtherCat on TMDS243EVM. Internet port is used for TCP connection, EtherCat port is used for EtherCat connection.
Just as before what I said, I want to add a TCP connection based on industrial_comms\ethercat_slave_beckhoff_ssc_demo, but this demo only has EtherCat connection, so I think I have to add a Enet (CPSW) in .syscfg.

Hi all,

I believe I've hit the same issue. I guess what Hongkai is saying that when using the industrial comms. SDK (I'm using 09.02.00.15) SysConfig doesn't show "Enet (CPSW)" or "Enet (ICSS)", only "ICSS-EMAC". When importing one of the Enet based examples (e.g. icssg_layer2_dualmac_am64x-evm_r5fss0-0_freertos_ti-arm-clang) the example builds (after fixing an issue with linked resources and include paths), but when opening the sysconfig file in the UI edtior the Enet settings are not visible.

This issue was previously described here https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1420167/am6442-industrial-communications-sdk-9-2-missing-configurations-in-sysconfig?tisearch=e2e-sitesearch&keymatch=enet%2525252520sysconfig%2525252520missing# and here https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1412093/processor-sdk-am64x-ti-networking-with-enet-cpsw-is-not-available-along-with-ti-industrial-toolkit/5452236#5452236

In the second thread there is a workaround from Tushar Thakur that worked for me. I'm not sure how "clean" that workaround is, as it disables some validations if I understood the change correctly. Maybe Tushar could comment on that (the other thread is locked, so can't comment there)?

Dominic

Hi Hongkai,

As Dominic mentioned, please try the workaround from the above thread (second).

Aaron

Hi Aaron,

My case is a little different with it, I want to run TCP server and EtherCat Slave on the same core(r5fss0-0). I tried the workaround from the above thread by Tushar Thakur.

My project is based on ethercat_slave_beckhoff_ssc_demo of ind_comms_sdk_am243x_09_02_00_15. After updating example.projectspec file, building project successed, then I tried to configure Enet(CPSW) according to ind_comms_sdk_am243x_09_02_00_15\mcu_plus_sdk\examples\networking\lwip\enet_cpsw_tcpserver for adding a Internet port, but it failed, see the capture.

Hi Hongkai,

I believe the failure on adding ENET instance is due to resource (pin) conflicts. If you scroll down, you will see which all pins are getting conflicted with that of EtherCAT. So in the AM243x-EVM, there are a total of 3 ethernet ports, 1 is configured for ICSS, 1 is configured for CPSW and 1 port is shared among both. Since you're using both the ports (1 ICSS + 1 ICSS/CPSW ) for EtherCAT, there will be a conflict when CPSW is configuring the shared port for itself.

May I know how are you trying to configure your example? Do you need 2 ports for EtherCAT and 2 ports for Enet(CPSW)? Based on your use case, we can provide the suggestion.

Resolving the conflicts should fix the current issue.

Regards,
Aaron

Hi Aaron,

Below picture is my request, thanks!

This should be possible by disabling the shared port from the TCP server example. I'll check on this internally and get back to you by Monday.

Regards,
Aaron

Hi Aaron,

Have you had any results from your internal disscussions?

Hi Aaron,

I did as what you said (Port 2 [Enet(CPSW) -> MAC Port Config -> MAC Port 2 Config -> Disable Mac Port 2] is disabled), but it still doesn't work, see below capture and my example.syscfg

Since you're running EtherCAT and TCP server on the same core, recommend to lower the priority of the EtherCAT task.

Why lower the priority of the EtherCAT task? In order to ensure real time and synchronous response, we used DC-Synchronous and give the EtherCAT task the highest priority. Can I understand that you don't recommend running EtherCat and TCP server on the same core? Would it be better if they ran on the different core?

Hi Hongkai,

Hongkai xiao said:

I did as what you said (Port 2 [Enet(CPSW) -> MAC Port Config -> MAC Port 2 Config -> Disable Mac Port 2] is disabled), but it still doesn't work, see below capture and my example.syscfg

• Can you show the pins which has the conflicts? You will need to manually make sure the pins and peripherals are configured correctly, avoiding overlaps.

• You are correct but I was referring to the fact that EtherCAT main loop has no sleeps and hence, it will be running continuously. When PRU is busy with EtherCAT processing, The R5F will be preempted by EtherCAT's higher priority and hence TCP/IP processing/interrupts will be delayed until the EtherCAT (PRU) task completes or is idle.

Hongkai xiao said:

• If the above timing constraint is fine for your use case, then you can use the same core. You will need to make sure that the EtherCAT task doesn't block the TCP/IP task for long periods. The RTOS should ensure that while EtherCAT dominates the execution time, the TCP/IP task still gets enough CPU cycles when PRU is idle or not processing EtherCAT frames.

Aaron

Okay, I believe you will have to pick the correct pin from the list of pins available for the CPSW example. Right now it is set to 'Any'. Fix this manually and then you should be able to resolve the conflicts.

Aaron

Could you give me a right choice based on TMDS243EVM? that way, I can move on, many thanks!

Hi Hongkai,

I'll check this internally and get back to you.

Aaron

Hi,

Hongkai xiao said:

You can drop down the conflict pin and select pin not used by other IP/instance.

Do you need RGMII1 and RGMII2 as per my understanding of your use case, it should be

CPSW-RGMII

ICSSG1-Port-1-RMII

ICSSG1-Port-2-RMII

Hi Ashwani,

I tried to config the pins, but there are many conflicts, see the captures. I am not sure if TMDS243EVM can be configured as my case,  

CPSW-RGMII

ICSSG1-Port-1-RMII

ICSSG1-Port-2-RMII

Hi,

Can you quickly try to configure resources here and then take changes in your project ?
SysConfig

Regards

Ashwani

Yes, I configured ICSS-EMAC as your picture, but pin conflicts persist. 

I wondered if it's possible to implement our requirements on the TMDS243EVM.

If necessary, I can send you my SDK and example.syscfg.

Hongkai -

 since you have both Ethernet/IP and EtherCAT involved, perhaps you should contact TI Freising Germany's (+) Thomas Leyrer's Profile - Thomas Leyrer - TI E2E support forums from the applications perspective.
