Overview

The OSAL library provides operating system abstraction layer API sample implementations that are required for processor SDK drivers. Scope of APIs supported in the module is limited to support OS services required for RTOS or bare metal drivers

  • Supported Operating Systems
    • TIRTOS
    • NONOS
  • Supported SOCs
    • Please refer to component release notes

Operating System Extension

APIs
Porting of OSAL component will enable extending PDK components to additional OS environment. Reference top level API header file  includes:

#include <ti/osal/osal.h>

Application Integration Details

Baremetal or No-OS Use case

Reference library path to be included in application build environment:

 <ti/osal/lib/nonos/[soc]/[[cpu]/>
  

SysBIOS based application

Any RTSC application that needs to use osal library, should have below RTSC configuration lines before any other processor sdk components (e.g., board, gpio, uart etc).


 /* set the operating system type, 
  * supported types are "tirtos" and "nonos" 
  */
 var osType           = "tirtos";

 /* set the soc type
  * (applicable only when osTYpe 
  *  is "nonos" only)
 */
 var socType           = "am572x";

 /* Setup the OSAL Library */
 var Osal = xdc.loadPackage('ti.osal');
 Osal.Settings.osType  = osType;
 Osal.Settings.socType = socType;
