Finboard - camera sensor and lwIP

I'm using BF-609 based Embedded Vision Starter kit , and I want to build an application that collects frames from camera, and sends them via UDP packets - so I use lwIP and camera sensor driver under uC/OS-III. Both camera and UDP work ok in standalone mode (I am able to send UDP packets in my local network, and can get non-empty handles to video frames from camera), but then I try to combine them in single application, camera part just stops working. I use Sensor.c and Sensor.h wrappers to camera driver from Video Pass-Thru Tutorial, and configuration part seems to work - no errors at least, but I can only get null-pointers to video frames. I suspect that there is some pins cluttering between camera and PHY hardware, maybe the source of the problem lays somewhere in softswitch_cfg.c from lwIP?
