freeRTOS + TCP/IP for NXP i.MX - examples/demos/docs

[nickw]

Hi all,

Still a relative newbie, but slightly less so than last time

I am using freeRTOS on custom embedded system hardware which uses NXP i.MX RT microcontroller. For now, I am using NXP mcuxpresso example project as a starting point. But I am wondering if actually we would be better doing this ourselves.

Please can someone point me at any relevant documentation, examples or demos on here?

I have seen this thread:

FreeRTOS+TCP - issue getting echo server to reply

For background, I have been working on getting FreeRTOS+TCP (10.3.1) ported to the iMX.RT1064 EVK and have been working through some issues with the Ethernet functionality. For background I have the kernel outputting the gratuitous ARP periodically as expected. The target also works reliable in terms of replying to pings sent to it. I am now working on verifying TCP and UDP operation. A simple UDP send loop on the target shows up on Wireshark as expected with the expected data in the payload…

thanks
Nick

It seems that @Dave has a FreeRTOS+TCP network interface for NXP i.MX RT microcontrollers, but this driver has not been added to the Github repo. Not sure if Dave is seeing this thread?

Here is another post from Dave where he announces developing a network interface.

Nick,

Sorry I haven’t been active on the forum to have seen this (thanks for the ping Hein). I was working with the same HW/SW platform as it appears you are and was successful in getting a driver ported to get the TCP/UDP stacks working correctly, at least with basic testing. I had to put the project on hold a while back and haven’t touched it in several months. I will try to blow the dust off of things this week and will be happy to share what I had. I am not real fluent in use of the Github repo so I did not post my past work there.
