hi, 
 
 I am facing a problem in sending data through Ethernet. in lwip i am calling function video to
grab image after grabbing image and placing data in buffer and if i call any other function the
code keeps running on and when i halt the code my code stops here. i am not able to solve this
issue . 
 
What i am trying to send data to my pc through Ethernet. i called video function to get image ,
then i called another function but i got this error . later i blocked the code i directly
called send function and i got same result.

 I hope some can solve my problem to  remove this error. I am working on BF537.

 waiting for reply eagerly.
