Below is an overview of the main ROM functionalities. For more details on ROM functions available, see the DriverLib documentation in the SimpleLink™ CC13xx and CC26xx software development kit (SDK).
The ROM is preprogrammed with a serial bootloader (SPI or UART). For applications that require in-field programmability, the royalty-free bootloader acts as an application loader and supports in-field firmware updates. The bootloader either executes automatically if no valid image has been written to the flash, or the bootloader can be started through a configurable GPIO. The bootloader cannot be called from application code.
