I assume you are saying that you were successful in asserting RSTCONF
and programming the HRCW back in.
* Is it the _correct_ HRCW? Do you know what it was previously?
* Did you _power cycle_ the board with RSTCONF deasserted? (the HRCW
only is read on a _power cycle_)
My experience (not with the Rattler) is that boards don't run well with
RSTCONF asserted. In my experience, I assert RSTCONF, program the HRCW
(and optionally u-boot), and then _power cycle_ the board. At that
point, the board should be functional enough to program u-boot (or
whatever) into it, reset, and run.
