The CC13x4x10 and CC26x4x10 device platform includes a simple ROM-based bootloader that can communicate with an external device over the serial interfaces on the UART0 and SPI0 peripherals. The same communication protocol is used on both serial interfaces. The UART is IP from Arm®.
The main purpose of the ROM bootloader is to support functionality for downloading a Flash image.
