TMDX654IDKEVM: NIMU_ICSS_BasicExample_am65xx_evm_mpuExampleproject not working

As my original thread was closed without any answer, I will ask again. Can anybody help us on this, as we are getting close to our project deadline:

Hi there,

The following is true for our setup:

Hi there,

The following is true for our setup:

- Code Composer studio v9.1.0.00010
- PDK for AM65XX v1.0.7 and Processor SDK RTOS 6.03.00.106
- XDC tools v3.55.02.22
- NDK v3.61.1.01

I have created the NIMU_ICSS_BasicExample_am65xx_evm_mpuExampleproject located at C:\ti\pdk_am65xx_1_0_7\packages\ti\transport\ndk\nimu_icss\example\am65xx\a53\bios using the pdkProjectCreate.bat file, where I believe the example implements 2 Ethernet Interfaces. For our application, it is designed that the CPSW port be used for normal TCP/IP communications with a PC. PRU2 will then be used as ModbusTCP interface, and later the other PRU's will be used for EtherCAT implementations. I am thus referring to the example above, as I will have to get all 7 ports on the EVM working simultaneously, and to register 2 Ethernet interfaces to the NIMU will be a good starting point.

Now referring to example project, I am unable to ping any of the ports using any of the 2 IP addresses (IP address specified in .cfg file as well as IP address in stackInitHookFxn). It is also unclear to me which port of the EVM is associated with which interface (the interface specified in .cfg or the specified in the hook function).

Is there something I am missing in this example? Could you please describe the setup of this example as well as how would I go about defining multiple interfaces to the NIMU so that different TCP/IP protocols can be handled by different PRU's / CPSW port?

This is quite urgent, as we have successfully managed to test ModbusTCP and normal TCP/IP communications over ANY port. However, as soon as multiple ports gets assigned to the NIMU, we are unable to ping any of the ports.

Any help will be appreciated as soon as possible!

Kind regards,

Johnny

Does anybody know how to get a response from TI on this?

Johnny,

Apologies for the thread not being replied to. Please advise if there is any change in status for your issue.

For the NIMU examples there are several included with the Processor SDK. The one for which there is a CCS project configures only two ports, as you mention.

If you look to the <pdk>\packages\ti\transport\ndk\nimu\example\am65xx\icssg folder there is an example you can build from the command line that supports multiple ports across instances.

Please take a look and see if this gets you further along.

Best regards,

Dave

Johnny,

If you look at the CCS documentation, http://software-dl.ti.com/ccs/esd/documents/users_guide/ccs_project-management.html#Creating_New_Makefile_project you are able to import a Makefile-based project into CCS and still have all the visibility into the source files and includes, etc.

To do so, you go to the Project Explorer pane and select New->Project then C/C++->Makefile Project with Existing Code

Go to the folder with the Makefile and import -- <pdk>\packages\ti\transport\ndk\nimu\example\am65xx\icssg

Best regards,

Dave

Hello Dave,

Thank you very much for replying. I tried to follow the procedure, but as usual, the example doesn't build. Did you try to build the example in CCS?

Kind regards,

John

Good afternoon,

We are working on this since June now and we get little to no effective support. The support level in general is very bad over the last months.

It is very frustrating that we cannot make this work. Is there any way TI can help us or are we forced to look for other options? It is great that you have 7 ethernet interfaces on this board, but it doesn't make sense if you cannot use them in TI RTOS.

In the mean time we managed to make all other functions from a previous design working under TI RTOS. It would be a tremendous waste of time if we have to start all over again.

Kind regards,

John

Good afternoon,

The support from Texas Instruments is very disappointing. On paper, the AM65x in combination with TI-RTOS is a perfect fit for our application, but with this level of support, incompatible tools and lack of documentation, it's all useless. Over the last two months we didn't make any progress and are stuck with a project that's finished for about 70%. If we don't get support and results soon, working with TI has been a compleet waste of time and money.

Kind regards,

John

Hi Johnny,

Apologies for the delay, we have been busy with other issues. None of that should concern you of course.

I am going to pick up this thread now. While I try to reproduce the issue, can you tell me if you see this issue with SDK 7.0 as well ? I see that you used the previous version of the SDK in your original thread.

Regards

Vineet

Hello Vineet,

Thank you for your reply. We also tested with version 7.0. I heard that in a couple of days a new version of the SDK will be released with different ethernet drivers. Would it be better to wait for this release? Do you have an example of using 2 ethernet ports with the new release? One of them should support TCP/IP and the other raw ethernet frames (for Ethercat master).

Kind regards,

John

Hi John,

The SDK 7.1 for AM65x was released a few days back and documentation for porting EtherCAT slave to it (on RTOS) was updated today. Here is the link

This does not address your question regarding EtherCAT master but I hope it serves as a reference.

Regarding general receive/transmit on PRU-ICSSG, there is some support on Linux through dual EMAC. You can see the documentation here . However the ICSSG firmware sources for this are not available at the moment and there are no immediate plans to release them.

Hi Vineet

The documentation you linked for porting an EtherCAT slave to SDK 7.1 says the following:

"NOTE: These changes enable build of projects on R5F core of AM65xx only".

Does this mean that the changes (instructions to be followed to port) only allow for projects to be built on the R5 core with SDK 7.1?
What does this mean for the A53 core?
We have projects for both of these cores.
Moving the A53 project to the R5 would require a lot of time.

Kind regards
Damon

Hi Damon,

1. Unfortunately, we don't have support on A53 core for EtherCAT slave example.

2. Regarding the original question "NIMU_ICSS_BasicExample_am65xx_evm_mpuExampleproject", we checked and found that, it has been verified in 7.1 SDK. Can you please check the status ? and let us know.

Also, I would request you to reach out through TI representative on this thread for further help.

Regards

Vineet
