# RL78 F13 IAR - Integrating Bootloader with Application code

Hi,

I'm using RL78 F13 MCU with IAR Embedded workbench.

I have a 3rd party bootloader developed in which i just need to specify the application start address.

I have to integrate my application code with bootloader code. Kindly let me know the procedure.

I have tried following approach.

1) Created a single workspace and added both the projects. Tried changing .ddf file for both.

Unable to compile the project.

Kindly let me know the procedure to integrate Bootloader & Application code in IAR RL78.

Thanks
