Hi Wolfgang,

It is my understanding that a rework of this code is under way which will avoid the long delay for the standard boot sequence (and only need it for board bringup or intentional recalibration).
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
Yes. I see this as a mandatory requirement. The additional delays are not aceptable.
I just want to raise some concerns about this approach on boards with DIMM modules. Here it will be hard to determine if a new DIMM module is installed. Even a module from the same manufacturer and type (size, width etc, all the same) will need a new autocalibration. This is probably hard to detect.
Just my $0.02.
Best regards, Stefan
