LWIP Problem

I’ve added LWIP library to my embedded project. Microcontroller STM32F107VC.

When I initialize the LWIP

LwIP_Init();

I get some errors:

section `.bss' will not fit in region `RAM'

region `RAM' overflowed by 18004 bytes

because the functions mem_init() and memp_init() allocate the memory and completely waist it. As I understand all the settings reside in

lwipopts.h that overwrites opt.h.

I tried different settings. Actually I took it from ST example - STM32F107_ETH_LwIP_V1.0.0.

What should I do to get it working?

Hi erenburg.evgeny.002,

I suggest you to start from the lwIP example under STM32cubeF1 package:

STM32Cube_FW_F1_V1.3.0\Projects\STM3210C_EVAL\Applications\LwIP

These examples guide STM32Cube HAL API users to run application based on Raw API of LwIP TCP/IP stack.

For more details about this application, refer to

''Developing applications on STM32Cube with LwIP TCP/IP stack''
