Running R11AN0909 Application on RA8D1 (EK-RA8D1) - Secure Bootloader Using MCUboot

I am trying to convert one of the application projects from R11AN0909 for use with the RA8D1 (EK-RA8D1).  Ultimately, I want to use MCUboot on my custom RA8D1 hardware.  That approach has also been unsuccessful, so I thought I would start simple.

Attached is a project which I tried to convert to work on the EK-RA8D1.  This is using MCUboot and overwrite from Program Flash.

It appears I have some issue with my debug configuration.  I get this message:

 EK-RA8D1_overwrite_with_bootloader.zip

If I proceed, the application crashes at BSP_SECTION_FLASH_GAP() in startup.c.

Anyone what to take a quick look at this project and offers some help?

Thanks
