GNU GCC and Kinetis USB MSD Bootloader

Hello,

has anybody succesfully compiled a working USB Mass Storage Device bootloader using GNU GCC for ARM Embedded toolchain.

I have several projects running with the ARM Embedded toolchain and would like to present customers with a bootloader which can present itself as a USB Disk.

I'm currently using the KL25z and files based mostly on AN4379.

However, when assembling Loader.c there are errors such as 'bad instruction: halt'.

Any help?
