The mach-mx28evk needs it too. If I put it into the iomux.h, what's the name for it? MXS_PAD_CTRL_12MA , or something else ? > OTOH the name sounds more generic than its use. Do you really need 12mA Yes, I need the 12mA for the Write protect pin, and other two pins. Best Regards Huang Shijie > for the Write protect pin?
