The application is running on Cortex M3 micro-controller. And it has 64k RAM
size, out of this my application hardly takes 10k RAM(not considering lwip
RAM size). 
After going through the code i found that for receiving it uses  PBUF_POOL
as well as PBUF_RAM. But while transmitting it uses PBUF_RAM only and
PBUF_RAW is used as pbuff_layer.
My requirement is large size of file transmission & reception simultaneously
which i m not able to achieve.
Please suggest suitable lwip configuration for my application.


Asma.
