I have available a compiled hex of both the UART Tunnel & USB
Bootloader useful for remaining in Windows during building and
troubleshooting your Tiny13. I found this to be quite useful when
building multiple units as you can switch between uBlox u-Center and
the Windows Phillips ISP programming utility and not dual boot back and
forth all day. It is also a great way to remove Linux/Debian from the
chain of variables during troubleshooting a Tiny.
Remember that airborne code cannot be "statically compiled" and
reused so this is not a solution for anything other than
building/troubleshooting. Airborne code includes the flight plan and
other dynamically changing content so must be compiled before each
flight or change.
