Hello, I’m trying to port freeRTOs to TI TMS320F2812 (32K ram). I would like to run a tcp/ip stack on this hardware using freeRTOs. I know that the tcp/ip stack’s data structures are huge. Is 32k enough to run freeRTOs and a tcp/ip app?

You can get TCP/IP to work easily in 32K of RAM, but the less RAM you have the lower the throughput will be.  Take a look at the uIP demos in the FreeRTOS download. Let us know how your port goes.
