Part Number: F28M35H52C
Tool/software: Code Composer Studio
My hardware is using an F28M35H52C connected to an external SDRAM. Everything is working fine with the SDRAM. I can read and write with large amounts of data on it.
the file of .cmd contain.
PAGE 1 :
RAML1 : origin = 0x009000, length = 0x001000 /* on-chip RAM block L1 */
SRAMCS0 : origin = 0x300000, length = 0x040000 //An 16Mbyte SDRAM chip connected to
SRAMCS2 : origin = 0x380000, length = 0x040000 //An 16Mbyte SDRAM chip connected to
.esysmem : > RAML2 PAGE = 1
if I leave my heap size at 0x1000 in the linker settings, I can use the calloc ,but when i use the 0x300000 ,the program will stay at the follow
/*-----------------------------------------------------------------------*/
/* Find the first block large enough to hold the requested allocation */
/*-----------------------------------------------------------------------*/
while (current != LIMIT && -current->packet_size < allocsize)
{
prev = current;
current = current->next_free;
}
I also find that if the address which prudeced by the calloc is bigger than the 0xFFFF , the mistake is also happen.
wf = (float *)calloc(nwf*nwf_L, sizeof (float));
I can't find what produce the problem, hope you can help me . thank you
