Introduction

The bim_oad_offchip is a small project used with the simple_peripheral project in OAD off-chip configuration; it is not used as a standalone project. It is a lightweight Boot Image Manager (BIM) that resides in the last page of internal flash and executes after the boot ROM. BIM for off-chip OAD is used to determine whether to run the existing application image or to copy a new image or images from off-chip flash to on-chip flash. Use the cc2640r2lp_app-FlashROM_OAD_Offchip configuration of the simple_peripheral application. See the OAD section of the BLE5-Stack User’s Guide for more information.

Hardware Prerequisites

The default BIM OAD Off-chip configuration uses the LAUNCHXL-CC2640R2. This hardware configuration is shown in the below image:

For custom hardware, see the Running the SDK on Custom Boards section of the BLE5-Stack User’s Guide.

Software Prerequisites

For information on what versions of Code Composer Studio and IAR Embedded Workbench to use, see the Release Notes located in the docs/ble5stack folder. For information on how to import this project into your IDE workspace and build/run, please refer to The CC2640R2F Platform section in the BLE5-Stack User’s Guide.

Usage

The usage of this project is explained in the OAD section of the BLE5-Stack User’s Guide.

By default, this project uses the following pins to access the SPI flash:

PIN	CC2640R2F Pins
IOID_FLASH_CS	IOID_20
SPI_MOSI	IOID_9
SPI_MISO	IOID_8
SPI_CLK_FLASH	IOID_10

These can be changed using the procedure described in the OAD Off-Chip section of the BLE5-Stack User’s Guideadd-off-chip-oad-to-an-existing-project).
