Hi, I am trying to run FreeRTOS 10.2.1 with lwIP-2.1 on a CORTEX\_A9\_Zynq702 platform, but the lwIP\_Apps.c (specifically lwIPAppsInit) that comes as part of the demo example only works with lwIP-1.4.

Is anyone aware of any attempt to run lwIP-2.1 with this FreeRTOS version?

Help is much appreciated,  
JT

I think the Xilinx tools (XSDK or whatever replaced it) will generate a FreeRTOS+lwIP project for you.

Not sure if you are aware of it, but FreeRTOS also has its own TCP/IP stack, called FreeRTOS+TCP. It has been ported for Zynq as well.

You can find more information on [FreeRTOS.org/tcp](https://freertos.org/FreeRTOS-Plus/FreeRTOS_Plus_TCP/index.html). There is also a sample projects for Zynq.
