4.1.2.2 Incremental Builds

This project is divided into two incremental builds. This makes it easier to learn and get familiar with the board and the software. This approach is also good for debugging/testing boards.

The build options are shown in Table 4-3. To select a particular build option, open the main.syscfg and select the INCR_BUILD to the corresponding build selection as shown below. Once the build option is selected in powerSUITE page and save button is clicked, compile the complete project by selecting rebuild-all compiler option. Next chapter provides more details to run each of the build options.

Table 4-3 Incremental Build Options
Incremental Build Options
INCR_BUILD = 1Peak current loop check with constant I command and open voltage loop (Check PWM drive circuit and sensing circuit)
INCR_BUILD = 2Closed current and voltage loop (Full PSFB)
