Abstract

In peripheral to peripheral communication, USB2.0 continues to occupy prominent position. With the emergence of USB2.0 peripherals, figuring out a standard, reliable and robust approach that can validate USB2.0 on System on Chip (SoC) is the need of an hour. The performance of USB depends fundamentally on electrical characteristics. Using this innovative approach (validation using U-Boot framework) we have root-caused several notorious issues which were hard to narrow down using legacy approach. This methodology possesses both the legacy capability of low level programming (JTAG) as well as of application level (High Level) programming (Linux). The paper is presented using case study of some issues which were reflected in the system using this methodology only.
