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. gvb
