Traction inverter is a typical application requiring both outstanding CPU throughput and flexible control peripherals. This work briefly introduces the architecture of a traction inverter reference design with AM263x software framework for traction inverters. Then, the focus stays on how to configure, change, and debug the traction inverter reference design with the software framework. A step-by-step guide is presented in order to help users understand details in the framework. On the other hand, a brief guide summarizes resources, tips, and tricks on code migration from AM24 and C28 family. It is critical to understand features and make adjustments during system design. After all, this work demonstrates a software framework to reduce the learning curve and accelerate the adoption of AM263x in traction systems.
