MCF51JM128 - Firmware does not work after upgrading with USB bootloader

I am trying to implement the USB bootloader for MCF51JM128. I added the bootloader into the demo code provided with the JM Badge Demo Board. Using JTAG, the firmware is working properly. After flashing with USB bootloader with the same firmware .S19, the firmware is no longer working.


I believe it could be a memory addressing issue as I am able to successfully flash a simple LED display firmware but not the demo firmware itself. Please help
