Are you talking about storing the optimized autocalibration values in FLASH, as discussed on IRC some time ago? I don't know if somebody is working on this. I only know that AMCC is working on a fix for the autocalibration on Kilauea. Not sure if this effects the bootup time, I can only hope it does. > For this > purpose, the row of dots is IMHO more useful than the spinning wheel. > > Assuming my understanding is correct (is it?), then we could fix this > now as well. Again, if you decide that that's the way to go, then I will not object.
