Peachy. My current automatic rig for the DCM475 flashes both images regardless now too. Also does readback/compare to ensure reliable flashing.
Well, that's an entirely different issue, which might become an issue for us... The SB6120 pulls about .5A through the 3.3V supply, and there are sometimes issues getting the flash to ID properly... Basically, a lot more read/write issues on the SB6120. Nothing that causes bricks for me, but sometimes a lot of hassles.
