[FreeRTOS Home] [Live FreeRTOS Forum] [FAQ] [Archive Top] [March 2006 Threads] Bug using pvPortMallocPosted by Nobody/Anonymous on March 22, 2006 Hello, we have ported FreeRTOS on the ADUC7026 Microcontroller and have sucessfully used pvPortMalloc from Heap_2.c for many purpose. But since we try to allocate memory for a certain Datastructure, it works correctly with the Keil simulator but abort when testing on the Ucontroller.
Here is the datastructure.
/*********************************************/ typedef struct txmsg { struct txmsg *next; /* Next in linked list. */ ABCSP_TXMSG *m; /* The message (reference) itself. */ unsigned chan:4; /* BCSP channel. */ unsigned seq:3; /* Sequence number. */ } TXMSG;
/******************* And here the code using that datastructure * ********************/
void testCalloc(void){
TXMSG * m; m = ( TXMSG * ) malloc ( sizeof ( TXMSG ) ); if ( m ==(( TXMSG * ) NULL ) ) /*Panic*/ ; else { m->chan=0; } } /********** End of the code ******************/
We stepped with the Keil Debugger on the Heap_2.c pvPortMalloc code and found that the System allways abort when trying to call: /* Insert the new block into the list of free blocks. */ prvInsertBlockIntoFreeList( ( pxNewBlockLink ) );
Please have even had a such problem ? Or do you have any solution for this?
Thank you in advance.

RE: Bug using pvPortMallocPosted by Nobody/Anonymous on March 22, 2006 Do you have portBYTE_ALLIGNMENT set correctly?
RE: Bug using pvPortMallocPosted by Nobody/Anonymous on March 22, 2006 portBYTE_ALIGNMENT is set to 4.
