It compiles and it works! On sockit: U-Boot SPL 2016.03 (Apr 05 2016 - 17:57:23) drivers/ddr/altera/sequencer.c: Preparing to start memory calibration drivers/ddr/altera/sequencer.c: CALIBRATION PASSED drivers/ddr/altera/sequencer.c: Calibration complete Trying to boot from MMC1 First time that an SPL built from a recent version has run successfully on that board. Will try it out on de0 tomorrow morning... Thanks! --George > > Best regards, > Marek Vasut
