CCS5 : fail to calloc() a large size memory?

Killo Lu

Hi,

When I use calloc() to allocate a memory (size is 26 MB), it fails (return 0)

But if I allocate a smaller size, it seems successful.

How can I allocate a 26MB memory if my program needs it?

Thank you.

How big is your heap? Check the linker map file (--map_file option) to see how big the .sysmem section is.

My heap is 32MB (0x02000000), which is larger than 26MB <--why?

The strange thing is if I change the heap size to 64MB (0x04000000), then it successes.

Are you allocating other large objects, or a lot of small ones?
