installed on the node during the joining process. More info in
Join Process.

dispatcher. For more information, see the Hwi module documentation in
the TI-RTOS Kernel (SYS/BIOS) User’s Guide.
Over-the-Air Download (OAD) Terms and Acronyms
- BIM
- Boot Image Manager
- A bootloader that runs after the device’s ROM startup code. The BIM is
responsible for analyzing the image header of all images and
determining the most suitable image to run. Once the BIM has found the
proper image, it will jump to it’s program entry.
- CRC
- Cyclic Redundancy Check
- An error-detecting code used to check the integrity of blocks of data.
- ECDSA
- Elliptic Curve Digital Signature Algorithm
- A variant of the Digital Signature Algorithm (DSA) which uses elliptic
curve cryptography.
- Factory Image
- The factory image is a “golden” image that resides in external flash
as a fail-safe mechanism.
- HIB
- Halt In Boot
- A mechanism in CC26xx and CC13xx devices to ensure that the external
emulator can take control of the device before it executes any
application code.
- OAD
- Over-the-Air Download
- The process of performing a device firmware update over the air.
- OAD Target
- The device whose firmware is being upgraded over the air. This is
assumed to be a CC26xx or CC13xx device running the TI
protocol-specific transport for OAD.
- OAD Distributor
- The device responsible for accepting an OAD enabled image from the
compiler and transferring it over the air to the OAD Target.
General Terms and Acronyms
- CCFG
- Customer Configuration
- Customer Configuration is set by the application and contains
configuration parameters for the ROM boot code, device hardware, and
device firmware. It contains lock-bits on the last page of flash. You
can read more in the Customer Configuration section in the CC13x2 CC26x2 SimpleLink Wireless MCU Technical Reference Manual.
