Hi, all, first time here.
We are starting a new project that requires an RTOS and TCP/IP over USB. More specifically we need/want to support MQTT:[https://www.freertos.org/mqtt/index.html], which is supported.
It looks like this project IwIP:[https://www.freertos.org/portsam7xlwIP.html] might be what I'm looking for. However, it looks like I need to pay for the CrossWork IDE to get access.
Anyone here have experience with the IwIP project or more generally TCP/IP over USB on FreeRTOS that is willing to point at the moon?

This forum focuses on AWS IoT connectivity with FreeRTOS, and up to now we don't support TCP / IP over USB. That should be possible to achieve based on FreeRTOS with one of several approaches, but I don't know of an out of the box example that will get you going quickly. Segger, a FreeRTOS partner, does have components that should be helpful, and all of their components can run with FreeRTOS in addition to their embOS (see https://www.segger.com/products/connectivity/emusb-device/add-ons/ip-over-usb/). You might want to try the FreeRTOS forums (https://forums.freertos.org/) although I expect you already did a search there, as the example you gave comes up when forming a query with the keywords in question. Asking again on that forum might well get new exposure and provide some useful suggestions. Best of luck.
