PRU CPSW source code

Hi Jim,

I cannot understand exactly what source code you are looking for. Can you explain in some more detail?

The PRU core is an entirely separate processor. It has its own opcodes. This is the wiki PRU portal, with links to different resources: http://processors.wiki.ti.com/index.php/PRU-ICSS

Jim,

IA-SDK examples that use the Gbit switch (CPSW) inside AM335x do not make use of PRU processing at all. However it requires special pin-muxing and board configuration (jumpers) to connect the phys on ICEv2 to CPSW. Full sources for that examples are included in IA-SDK.

Most protocol implemementations however require the PRU-ICSS which implements MAC in software and also uses the dedicated PRU MII interfaces (10/100 only). The PRU fimware sources are not available but the ARM side drivers are. For the rest see IA-SDK docs.

PRU architecture is documented in AM335x latest TRM and is NOT ARM compatible in any way.

Regards,

Frank,

as I've written before, what I really need is the layout of the Forward Decision Table and Receive Decision Table from the Profinet example code. I've have been through all the documentation and all the available source code and it is not documented.

Jim

Jim,

yes, that is understood and your request has been forwarded. I assume this thread will get updated once the doc is available.

regards,

thanks Frank. is there any chance you can give me an estimated time for having the doc available.
I assume you have my email if you need to communicate with me directly.
Jim
