FreeRTOS + lwIP

Hi, I have still the same target but I cannot find a solution for OS crashing. I open socket on TCP port 80 (I have server from lwIP_Rowley_demo) and then OS crashes. I did analize the track to halt: (tcp_in.c) tcp_process -> (tcp.h) TCP_EVENT_ACCEPT -> (tcp.c) -> (api_msg.c) accept_function -> (sys_arch.c) newconn->recvmbox = sys_mbox_new(); -> (queue.c) xQueueCreate -> crash Have you idea? Please for help! Janusz

I trace in xQueueCreate: crash is during: pxNewQueue = ( xQUEUE * ) pvPortMalloc( sizeof( xQUEUE ) ); I am using heap_2.c, FreeRTOS 4.1.0, lwIP 1.1.1, GCC ARM7 AT91SAM7S256 Janusz

Is the crash actually inside here, or is it just returning NULL? If it is inside then check your byte alignment constant. If it is returning NULL then you need to increase the heap size.

it crashes inside pvPortMalloc. I have tried to increase heap size – without effect.

After crash Data Abort interrupt is generated.

solution: -O1 or -O2 compiler option Janusz P.S. I do not believe in power of GCC for ARMs like before…
