Part Number: TMDS243EVM
Other Parts Discussed in Thread: SYSCONFIG, DP83869

Tool/software:

Hi Ti Expert,

Our own designed board's hardware are like this: ICSSG0 + two DP83826 for EtherCAT; CPSW0 + two DP83867 for EtherNet.

These EtherCat and EtherNet could work together on one single R5 core is what I am after.

Using the new ind_comms_sdk_am243x_11, I can complete the sysconfig following the blow two demo.

ind_comms_sdk_am243x_11_00_00_08\examples\industrial_comms\ethercat_slave_beckhoff_ssc_demo\am243x-evm\r5fss1-0_freertos -- my project base on this demo.

mcu_plus_sdk_am243x_09_02_01_05\examples\networking\lwip\enet_lwip_cpsw\am243x-evm\r5fss0-0_freertos

There is no pin-conflict. And after I adding the include path, according to the CPSW demo, the Build is completed.

Then I found

---- sorry for the misoperation---

Then I found the ti_board_config.c in my project is almost empty, not like the one in CPSW demo, which contains EnetBoard_getPortCfg(), EnetBoard_findPortCfg as so on.

When I try to add ETHPHY (Enet CPSW/ICSS) under TI Board Drivers in Sysconfig, there is a Warning like the following.

Warning : Ethphy device is not linked to a network peripheral

Could please guide me here and tell me what is the best way to make CPSW work beside EtherCAT?

Thanks & BR,

Chunyang

Hi Chunyang,

I tried doing this with latest MCU PLUS SDK.

On Adding the Enet (CPSW) from syscfg, and adding the relevant folders in Include Options. It is building without errors.
The ti_board_config.c file being empty issue is not there anymore.

You can try the CPSW example from ind_comms_sdk_am243x_11_00_00_08\mcu_plus_sdk\source\networking\enet\core\examples\lwip\enet_lwip_cpsw\am243x-evm\r5fss0-0_freertos and check which all folders are there in Include Options. You can check include options at Properties -> Build -> ARM Compiler -> Include Options

Then in the EtherCAT Example, I added the Enet (CPSW) in sysconfig and added the relevant folders in Include Options which I got from enet_cpsw example.

Meanwhile we are still working on this.

Hi Keshav,

Thanks for you help.

I do not know why this cpsw demo can not work from Ind_SDK_11, but can work from SDK 9.2 in my side.

But it's doesn't matter, our goal is to run CPSW under EtherCAT demo.

Looking forward for your update.

Many thanks!

Hi Chunyang

Please read the second note on this page https://software-dl.ti.com/processor-industrial-sw/esd/ind_comms_sdk/am243x/11_00_00_08/docs/api_guide_am243x/index.html

Once you get the relevant Include paths from here. You can add Enet (CPSW) in your EtherCAT example sysconfig.
After this you can try merging EtherCAT and Enet (CPSW) mains

Hi Keshav,

I followed your guide to add ${SDK_INSTALL_PATH}/mcu_plus_sdk path to "Product discovery path" in CCS (from Window->Preferences->Code Composer Studio->Products).

But as the following screenshot shows, there are still the Warning : Ethphy device is not linked to a network peripheral

And the driver file such as dp83869.c does not be included too under the project folder.

The build can pass, but ti_board_config.c is still almost empty.

Looking forward to your reply!

Hi Keshav and Ti expert,

Any update from you for my issue?

Our own designed board's hardware are like this: ICSSG0 + two DP83826 for EtherCAT; CPSW0 + two DP83867 for EtherNet.

For ICSSG0+DP83826, I have other thread on E2E to track.

For this thread I'd like to solve CPSW0 + two DP83867 for EtherNet under ind_comms_sdk_am243x_11, and integrate Ethernet to EtherCAT.

Please help me with it.

BR,

Hi Chunyang,

When I tried the ti_board_config.c wasn't empty.

Let me explain what I did.

Load the following example into CCS

ind_comms_sdk_am243x_11_00_00_08\mcu_plus_sdk\source\networking\enet\core\examples\lwip\enet_lwip_cpsw\am243x-evm\r5fss0-0_freertos

then check which all folders are there in Include Options. You can check include options at Properties -> Build -> ARM Compiler -> Include Options

It will look like the image below

Then load your ECAT example and go to example.syscfg and add ENET (CPSW) not ETHPHY (Enet CPSW/ICSS).

Go to include options of ECAT example and add relative paths that you saw in CPSW example.

Then after building, the ti_board_config.c file should be mostly empty.

We haven't worked on the Warning: Ethphy device is not linked to a network peripheral. We will get back to you once we have any updates.

Hope this helps.

Regards,

Keshav

I think we are on the same step as this is what I have done.

If we did not add TI Borad Derivers-> EthPhy(Enet CPSW) in sysconfig, the project can pass Build, and there is no this Warning.

I haven't run this project in my board, do you think it would work if I initial IWIP in this project?

Hi Keshav,

Is there any update from your side?

Could this CPSW-Enet work(establish connection or ping) under EtherCAT demo project?

Hi Chunyang,

This combination should work (Ethercat and CPSW Enet) . You can use lwip enet example for this. Let us know if you face any issues with this

Hi Prajith,

Just as Keshav did above, I have done the following.

1 Load ECAT example and go to example.syscfg and add ENET (CPSW) not ETHPHY (Enet CPSW/ICSS).

2 Go to include options of ECAT example and add relative paths that in CPSW example.

3 Build the project without error. But, ti_board_config.c file is mostly empty.

Then I copy all the related .c and .h files from mcu_plus_sdk\source\networking\enet\core\examples\lwip\enet_lwip_cpsw\am243x-evm\r5fss0-0_freertos to the local of my project, such as dp83867.c, dp83869.c, generic_phy.c, test.c, test_enet.c, test_enet_cpsw.c and so on.

When I build the project again, there are some error as the following.

In file included from ../src/test.c:112:
C:/Users/cfue07770/workspace_v12_8_1/MCU_Board_Test/Debug/syscfg\ti_enet_lwipif.h:43:34: error: unknown type name 'LwipifEnetApp_Handle'
43 | void LwipifEnetApp_startSchedule(LwipifEnetApp_Handle handle, struct netif *netif

C:/Users/cfue07770/workspace_v12_8_1/MCU_Board_Test/Debug/syscfg\ti_enet_lwipif.h:46:47: error: unknown type name 'NetifName_e'
46 | struct netif * LwipifEnetApp_getNetifFromName(NetifName_e name);

49 | #endif /* TI_ENET_LWIPIF_H_ */

I think the cause of these errors is the Generated Source just as ti_board_config.c, ti_enet_lwipif.c is totally empty. But in enet_lwip_cpsw demo, they are not empty at all.

This is the issue I am facing.

lwip enet example

you meant I should use some other demo example rather than enet_lwip_cpsw?

Thanks

Hi Prajith and Keshav,

Following your guidance, I thought I was on the right way, and would reach success soon, til now, I am stuck again.

The following are the process which I worked both on CCS CCS 20.0.1 and CCS 12.8.1, come to the same results.

1, import ethercat_slave_beckhoff_ssc_demo_am243x-evm_r5fss0-0_freertos_ti-arm-clang build OK

2 Copy sysconfig from ethercat_slave_beckhoff_ssc_demo_am243x-evm_r5fss1-0_freertos_ti-arm-clang build OK

3 In sysconfig: add Enet(CPSW), EthPhy(CPSW/ICSS) would be added automatically. Modify the EthPhy device to DP83867 both. And copy the Include Option from enet_Lwip_cpsw project. build OK

4 From enet_Lwip_cpsw demo, copy all the related files(.c and .h) and folderextPhyMgmt to local. Except Main.c which is from ethercat_slave_beckhoff. Add ENET_ENABLE_PER_CPSW=1 to Predefined Symbols, Build OK

5 add following to main.c

#include "ti_drivers_open_close.h"

#include "ti_board_open_close.h"

Build OK

6 When I try to call enet_lwip_example() there are errors as following

After modify linker.cmd, the MEM error is fixed. but the "undefined symbol'", "first referenced" I have no idea how to fix them.

Please help me with this!

This likely means that you are not including one or more files where those symbols are defined. Let me take a look and figure out what is missing.

Hi Chunyang,
I am unclear on which example you are using as enet_Lwip_cpsw demo. Can you please clarify its location in the sdk.

0 chunyang fu 3 months ago in reply to Keshav Tiwari

Hi Keshav,

Demo enet_Lwip_cpsw's location as the following,

C:\ti\ind_comms_sdk_am243x_11_00_00_08\mcu_plus_sdk\source\networking\enet\core\examples\lwip\enet_lwip_cpsw\am243x-evm\r5fss0-0_freertos

Thanks for your kindly help!

Hi Chunyang
I checked the files where these symbols are defined. These files are in C:\ti\ind_comms_sdk_am243x_11_00_00_08\mcu_plus_sdk\source\networking\enet\core and I believe they are not being included in your project.

Can you please confirm that you are adding ${SDK_INSTALL_PATH}/mcu_plus_sdk path to "Product discovery path" in CCS (from Window->Preferences->Code Composer Studio->Products).
