[lwip-users] LWIP 1.4.0: migration from 1.3.2

[Dance, Brian]

Hi,

 

  I have migrated a Stellaris example of LWIP use with SafeRTOS from 1.3.2  to 1.4.0.     It is the safeRTOSdemo example on the Stellarisware CD in case anyone knows it.

 

  It was working OK on 1.3.2.

 

  I have followed the Upgrade note  and made changes to sys_arch.c and added timer.c and def.c

 

  On 1.4.0  it hangs the system.   It seems to be hanging in mem_malloc.  cc.h has #define LWIP_COMPAT_MUTEX  1

 

  If  I replace the hanging call of mem_malloc  with  statically allocated memory the application proceeds a little further but soon hangs up again.  The ethernet interface has no cable connected so it can't be receiving data.

 

Is there perhaps something I need to change in lwipopts.h?

 

There must be a lot of combinations to test.  Has 1.4.0 been tested with an RTOS and using binary semaphores as mutexes?   

 

 

Any suggestions would be welcome.

 

Regards

 

Brian
