I am trying to increase the heap memory available to me in my application, for which purpose I got a TWR-MEM.
For places where I want to use a different memory pool (the one from the TWR-MEM) I used the _mem_create_pool() with the External MRAM Base and Size as arguments.
_MRAM_pool_id = _mem_create_pool(BSP_EXTERNAL_MRAM_RAM_BASE, BSP_EXTERNAL_MRAM_RAM_SIZE);
if(_MRAM_pool_id == NULL)
I then use the function as shown below for mallocs on the External SRAM
pointer mram_alloc(int mem_size)
return _mem_alloc_from(_MRAM_pool_id, mem_size);
The code I am using was something I got off the forum. (and thank you to the one who posted this)
The problem I am facing is that everytime I called the mram_alloc I end up with the hard-fault which is triggered by the _lwmem_alloc_internal() funciton in lwm_alli.c.
I feel I am doing something fundamentally wrong here. If anyone has any pointers I would appreciate it.
