Forum Post: RE: sys bios - iheap and dynamic memory allocation

Hi Arpan,

You can place the SYS/BIOS system heap by adding the following lines of code to your *.cfg file:

var BIOS = xdc.useModule('ti.sysbios.BIOS'); BIOS.heapSize = <heap size in bytes>; BIOS.heapSection = ".esysmem";

The above assumes that there is an output section called ".esysmem" in your linker script that is placed in the desired memory segment.

(Please read section 6.7.2 in the SYS/BIOS user guide for more info on how dynamic memory allocation works - http://www.ti.com/lit/ug/spruex3m/spruex3m.pdf)

Best,

Ashish
