Zynq FreeRTOS-Plus-UDP

Posted by raymadigan on October 6, 2016

I was looking at the source tree this morning as I was halfway done building the FreeRTOS-Labs Zynq Demo for TCP. The demo includes many good technologies but all I really need is TCP/UDP connectivity. My usual practice is to build the full demo for the Zynq and then remove the FAT/FTP/HTTP/CLI functionality.

I saw this new functionality and wonder if I can use it to get right to the functionality I want. The issue is it doesn't have the Zynq NetworkInterface directory. Can I use this UDP functionality with the Zynq Network inerface from the FreeRTOS labs contribution? It would save me a pile of work.

First - apologies for the delay in your post appearing. It was unfortunate enough to be the one in a hundred that randomly got put into moderation, even though moderation is switched off.

I was looking at the source tree this morning as I was halfway done building the FreeRTOS-Labs Zynq Demo for TCP. The demo includes many good technologies but all I really need is TCP/UDP connectivity.

Do you mean you just need TCP/UDP connectivity without any of the other bells and whistles?

My usual practice is to build the full demo for the Zynq and then remove the FAT/FTP/HTTP/CLI functionality.

Which would seem reasonable.

I saw this new functionality and wonder if I can use it to get right to the functionality I want.

Um, which new functionality?

The issue is it doesn't have the Zynq NetworkInterface directory. Can I use this UDP functionality with the Zynq Network inerface from the FreeRTOS labs contribution? It would save me a pile of work.

Sorry - I'm confused. Are you talking about the older FreeRTOS+UDP stack found in the FreeRTOS download, Rather than the newer FreeRTOS+TCP stack found in the labs download? If so, I would not recommend doing that as the interface is not going to be compatible - it could be done for sure but would require some effort. If all you need is UDP then you can set ipconfigUSE_TCP to 0 in the FreeRTOSIPConfig.h header file. The Zynq demo won't build if you do that, but you can strip out all the example code and just start with the UDP command console, which has no TCP dependences.
