Add data for this sections in your app (for example in main.c file):

2. Flash MPC5744P.rbf file into MCU. You can create new empty project or use existing one. Start debug Configurations and Browse MPC5744P.rbf file (located in [YOUR_RAPPID_INSTALL_FOLDER]\RBF_Files. Start debug session.

3. Modify your EVB - add jumper wire from J3-4 to J2-16 and J3-2 to J2-14. RAppID uses UART0 and to USB is connected UART1.
4. Start RAppID BL tool, select COM port where EVB is connected, choose your s-record file and Start Boot Loader:
