There is a problem with MCF51jm128 mass storage HOST USB project.
The project is building correctly, no errors 'Finished building target: cfv1usbjm128.elf'.
If i debug the project,i hit run button, the code waits for USB stick to be plugged in, after i plugg in the USB stik, the program, goes in mcf_exception_handler -->"Illegal instruction" (this with CPUCR.IRD.bit =1) otherwise the mcu will reset itself.
Now, if use the flash programmer to write the code i receive a programming warning:
"Programming warning. Can't program 512 bytes to address 0x803e00 because this range isn't included in the selected modules! "
I think is a problem with the Project.lcf file provided with freescale USB stack.
