Memory allocation using malloc/calloc problem in USB Stack

vikashkumar — Mon, 27 Mar 2017 12:16:36 GMT

Hi,

I'm working on USB host integration. In usb_khci_preinit() function i'm trying to allocate memory at run time using malloc.

I tried with OS_Mem_alloc_zero(sizeof(usb_khci_host_state_struct_t)); function as well as int *p=malloc(10);.

In both cases i got return value is 0. It means i unable to allocate memory.

I need some help to solve this problem.

Check that the linker script allocates any heap memory.
