SBL NULL

Introduction

This is a bootloader which does SOC initializations and put all the cores in WFI. This example is what is referred to as the SOC initialization binary in Flash SOC Initialization Binary. The SBL NULL does not load any images on the cores. For more information on how this example is being used, refer Flash SOC Initialization Binary

Supported Combinations

Parameter Value
CPU + OS wkup-r5fss0-0 freertos
Toolchain ti-arm-clang
Boards am275x-evm
Example folder examples/drivers/boot/sbl_null

Steps to Run the Example

Since this is a bootloader and is used as a SOC initialization binary, the example will be run every time you boot an application using this example. It is generally run from a boot media (OSPI Flash, SD Card) unlike other examples which are usually loaded with CCS. Nevertheless, you can build this example like you do for the others using makefile or build it via CCS by importing as a project.

Note
This example is not supported for HS-SE devices as JTAG can not be connected to HS-SE devices by default.
