TPS2674x-Q1 requires firmware to run the Arm Cortex-M0+ core. The firmware format is referred to as a TI Firmware Update (TFU) image. Texas Instruments provides the base firmware and configuration examples to aid initial system development.

The user may also create a custom configuration tailored to their system needs using the GUI. Consult the Application Customization Tool User's Guide for complete details. Once the base firmware and custom system configuration are combined into a TFU binary file, the final binary image can be flashed to the device.
