Is anyone using the freertos sdk with lwip raw ?
SDK I am using is 1.3.0 from nov 2 (latest).

When I am using this combination I have lwip issues : tcp_sndbuf(..) always returning zero.
Already down to the most basic example program, which should rule out application issues.

I am trying to move software from iot-sdk to freertos-sdk. iot-sdk os OK.
The trial also complies and runs using the esp-open-rtos sdk.

Tried to use the lwip libraries from iot sdk, and esp-open-sdk but that doesn't go. Lots of undefined references and other..

Any help or links appreciated.
