  I'm porting a FreeRTOS firmware. It works well on task and it is able to do 2 led blinking tasks. Now I would like to port the uip LAN code. After I port the code, it starts to auto break a specific line. I have search :

  They say most probably is an exception but I can't check the exception message. I tried both delete the .metadata folder and create a new project but still the same. So I sure is code problem because this happened after I added the uip code.

I'm using :
1) Red suite 4
2) FreeRTOS v7.4.0
3) LPC2368
4) CR-JR ARM7 development kit

I have attached my src code and makefile those. It breaks at portISR.c line 130 : portSAVE_CONTEXT();

Here is the console screen I have:
1) C-Build
**** Build of configuration Debug for project RTOS Sample4 ****

make all
make: Nothing to be done for `all'.
