I don't do step 2 in my app. (I don't know what DCC is, either...)

I link my app with the image to be burned.  To my app, the
image to be burned is just a section of memory containing
bytes.  My linker script makes the starting/ending addresses of
that image section visible so my app knows where the image data
is in RAM. The linker creates a single application image that
contains the flash burning program as well as a copy of
whatever is to be burned into flash.

That's what my little app does.

I don't know of any.  Burning flash is usually fairly simple,
but it varies slightly from one flash vendor to another and
even from one board layout to another.
