2.1 EVM Setup for PPC3 Configuration

The shared boost configuration can be tested using TAS2120EVM, TAS2320EVM and the AC-MB controller board provided in either of the EVM kits. With this EVM connection, PPC3 can be used to generate the required command script that is used on the end application for testing and final configuration.

The necessary connections between the boards are described in Figure 2-2.

The hardware settings on EVM must be modified as described in Table 2-1.
