We have realize a custom board with dm648 to acquire images from a camera and send captured frames to a remote pc on a local network. We have tested board in full configuration (i.e. capturing frames from a camere through video port and sending them through ethernet connection). After above 200-300 frames the board stops to work. We have tested completely the video port driver and task, they work fine. Now we are testing only ethernet task and ndk, simulating frames with a buffer of [250*1024 bytes], and also in this case the board halts after 200-300 transmissions(we read _halt_util, we check also stack size and there are not stack overflow)! In our board we connect physically only one marvell PHY and the other one is not connected!! so we read in the stdout windows debug messages warn that one PHY is not found! What we can check or what we do wrong?

David
