[FreeRTOS Home] [Live FreeRTOS Forum] [FAQ] [Archive Top] [September 2006 Threads] FreeRTOS + lwIPPosted by Nobody/Anonymous on September 1, 2006 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
RE: FreeRTOS + lwIPPosted by Nobody/Anonymous on September 1, 2006 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

RE: FreeRTOS + lwIPPosted by Nobody/Anonymous on September 1, 2006 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.
RE: FreeRTOS + lwIPPosted by Nobody/Anonymous on September 1, 2006 it crashes inside pvPortMalloc. I have tried to increase heap size - without effect.
RE: FreeRTOS + lwIPPosted by Nobody/Anonymous on September 1, 2006 After crash Data Abort interrupt is generated.
RE: FreeRTOS + lwIPPosted by Nobody/Anonymous on September 3, 2006 solution: -O1 or -O2 compiler option

P.S. I do not believe in power of GCC for ARMs like before...
