That's an old version. I suggest you download the latest users manual. I have rev. 1.14 (Sept. 2) here. > it seems that the datasheet is wrong and suggests > using of ALT2 mode for the RGMII2 gpio pins(does not work) as opposed > ALT1 used in glacier (and actually working apart from a problem I > still am seeing with the TX). Do you remember anything about this? I remember that the early manual had some problems. GPIO being only one of them. Not sure if this is really fixed in the current manual. But the U-Boot code should show what's really correct. Code can't lie! ;) Best regards, Stefan ===================================================================== DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: +49-8142-66989-0 Fax: +49-8142-66989-80 Email: [EMAIL PROTECTED] ===================================================================== _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
