Thanks for debugging this, according to the Bananapro schematic VDD25-SATA either comes from a dedicated WL2003E25-5 linear regulator, or it is connected to LDO4 via a 0 Ohm resistor. So it would seem that in practice it seems that LDO4 is used, can you give the attached patch a try ? Regards, Hans -------------- next part -------------- A non-text attachment was scrubbed...
