Would electrically isolating the SPI bus from the MCU during programming be possible/help solve the problem? I was thinking a tristate bus which is controlled by the reset pin ...
Why not just a single gate to shut off the clock when RESET is active? Or, a single bus switch to disconnect the chip enable? Surely it's not necessary to isolate *all* the signals. You can get individual gates and bus switches in really tiny packages.
