Hello,
In a C6416 project we've upgraded from BIOS 5.20.05 to BIOS 5.33.06. We use MEM_define() to generate 120 heaps, we use a heap for each channel in our application. The following code is called from main():
#define SMEM_NO_SWOBJ_MAX 120
for ( n1 = 0; n1 < SMEM_NO_SWOBJ_MAX; n1++ )
{
/* init and allocate external object memory */
SMEM_obj.segTab[n1].id = MEM_define(SMEM_extObjTab[n1], SMEM_EXTOBJ_SIZE);
SMEM_obj.segTab[n1].pSeg = SMEM_extObjTab[n1];
SMEM_obj.segTab[n1].pData = SMEM_extObjTab[n1];
}
With BIOS 5.20.05 the following amount of memory is used:
Name largest free used total start end
IDRAM0, 0x25d38, 0x28108, 0x9f8, 0x28b00, 0x32c08, 0x5b707, 0
But when doing the same on BIOS 5.33.06, nearly all the memory in IDRAM0 (BIOSOBJSEG) is used:
Name largest free used total start end
IDRAM0, 0x23d0, 0x23d0, 0x26730, 0x28b00, 0x32c08, 0x5b707, 0
Then we tried to call MEM_increaseTableSize before the loop:
/* for the maximum number of swappable objects */
stat = MEM_increaseTableSize(SMEM_NO_SWOBJ_MAX+20);
if(stat != SYS_OK)
{
DBG_stdErr1(DBG_ERR_SMEM_CREATE, "SMEM_init: MEM_increaseTableSize failed: %d", SMEM_NO_SWOBJ_MAX);
return(SMEM_RET_ERR_FAILED);
}
And now less memory is used with 5.33, but still sligthly more as with 5.20:
Name largest free used total start end
IDRAM0, 0x27f78, 0x27f78, 0xb88, 0x28b00, 0x32c08, 0x5b707, 0
What is the reason for this behavior?
Thanks in advance!
