I have problem with trampoline for UC3B0256 device.
Programming by AVR Studio 5.
trampoline.S was not found in ASF. I tried google and found
that in new ASF files are renamed to trampoline_uc3.S
How can I set AVR studio 5 to enable trampoline with 16kB boot size? |

First I suggest to update to Atmel Studio 6, since it is the better AS5. This should directly fix your problem with the missing trampoline code.
Why are you wanting a 16kb boot size? The trampoline code only makes sense if you want to use the USB DFU Bootloader, but there you are stuck with a 8kb trampoline size. |

I have no idea about Atmel Studio 5 or 6 IDEs
but basically you can adjust the start address of your application
in trampoline_uc3.h by defining a different
PROGRAM_START_OFFSET
but of course your bootloader must evaluate that define in its startup code, too.
