AM5718: Latest SITARA AM57x SDK Linux not loading PRP/HSR firmware to PRUSS

Hello Gonzalo,

Just to make sure, you are testing these protocols with the recommended setup of two boards connected to each other?

-Josue

Hello Josue,

I fail to understand what the connection between devices has to do with the SDK documentation commands returning errors...

Could you please elaborate on this matter?

Best regards,

Gonzalo

Hello,

Any thoughts on this?

Gonzalo

Hello Gonzalo,

I apologize for the delay here. On my previous comment, you are correct that there is no connection between the application returning errors and the physical setup. I am not very familiar with this subject so I assumed the app might have a dependency on the boards being connected. 

With regards to your problem, this is another case similar to https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1217997/am5718-how-to-configure-eth-switch-mode-and-rstp, where there are know issues with this usecase and I need to check up with the development team.

Is this still an issue for you?

-Josue

Hello Josue,

Of course it is still an issue that we would like to know how to deal with.

Best regards,

Gonzalo

Ok Gonzalo,

I will reach out to the development team and report back by the end of the week.

Regards, 

Josue

Hello Gonzalo,

I was unable to meet with our dev team due to them being OoO for multiple reasons this week. I will sync with them next week and post what I find out. Please expect a reply from me by next week.

Hello Gonzalo,

It seems these protocols were not upstreamed, therefore the documentation is indeed out of date. 

Unfortunately there is no plan to support these on AM57 in the future at this moment.

-Josue

Hello Josue,

What do you mean with protocols not being upstreamed? PRP/HSR are basic functionality of our devices that must be supported in the coming years.

 Will these protocols no longer be supported by PRUSS and everything will be left to the Linux kernel? How will this affect Ethernet packet processing times and performance of the SITARA AM5718 in this scenario?

Regards,

Gonzalo
