    Hi,

    EMIF configuration tips for the AM437X are currently being prepared. I can't give an exact date when they will be available.

    We are now supporting h/w leveling for AM437x.  You can check the CCS GEL file here http://processors.wiki.ti.com/index.php/OMAP_and_Sitara_CCS_support#AM437x

    for an example.  The latest uboot for AM437x will also support this.

    H/W leveling will work on any board.  You will not need to go through the software leveling procedure.
