Hi Diego!

I agree that ultimate solution would be to recognize the format by
parsing input files. I am afraid though this will over-engineered, as
what we simply need is a barrier stopping from making 'stupid' errors
like wrong firmware format. Given that compilation results in both .hex
and .bin files one should not confuse them in case such a warning would
be shown. As a whole this should limit 'bricking' [1] incidents drastically.

Your reply given me an idea to extend the error message with 'Please
refer to upgrade manual'.

[1] Bricking as in making firmware update with regnual impossible
