pretty sure that get's overriden when the mmc core probes the eMMC/microSD.. So if you really want to disable 50/52Mhz you'll have to disable the actual sd transfer modes.. see for example on the x15, since we don't have a dual voltage regulator, these modes must be removed: https://github.com/RobertCNelson/dtb-rebuilder/blob/4.4-ti/src/arm/am57xx-beagle-x15.dts#L109-L113 Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
