Please note this is the "Tiny Bootloader" and it works just fine for thos=
e
chips
it "knows" about.  I do not think the 18F6720 is in its internal list of
know
chips, so you will likely have to experiment to find something "nearly" t=
he
same
to allow "Tiny" to program your chip.  That is not to say it won't work -=
 I
had
to do that to get it to program the 18F4520 and 18F4620. It does both but
has some minor issues when doing so.  However, it is free and relatively
easy to use.  Give it a try.
