Hi,

I am trying to establish a host to target communication via TCP/IP with TMS320F28386 on a custom Hardware. The connection to the PHY is the same as on the controlCARD (TMDSCNCD28388D), just a few GPIOs are different (e.g. Tx Data Pins, ERR Pins and so on).

I already checked the PHY register with CCS with expected results. So it is indeed working, but can't get it to work in Simulink.

FYI: I already got it successfully working with the controlCARD (TMDSCNCD28388D). So I think the working principle with my model should be okay.

In my opinion I have to change the GPIOs in the config-file, but the problem is: I can't even find/open the .config-file for any changes in Simulink.

Thanks a lot!

Hi Baris,

I understand that you are interested in establishing host-to-target communication via TCP/IP with TMS320F28386 on custom hardware and making changes to the GPIOs in the config-file.

To navigate to the config-file, please follow these steps:

Verify that the Hardware board in Hardware settings is configured properly.
Proceed to Create > Build options > Target hardware resources.
Within the build options, you will find the CSS hardware configuration file.
You can then edit the .ccxml file to configure the GPIOs according to your custom hardware.

I hope this resolves your query.

Thanks,

Rangesh.

Hi Rangesh,

thanks for your answer, but could you maybe give me an example?

Due to the fact that the .ccxml-file is not in C, I have no idea how to edit it.

Rangesh,

I am having issues related to a custom design (except that I am using a TMS320F28388, not the TMS320F28386). As far as I can tell, the CCXML file does not seem to have any information related to the pin configuration on the uP. Please correct me if I am missing something.
