The 'new timing mode' with 8 bits DDR works correctly when the NewTiming register is set.What does that mode brings to the table?From my tests, the eMMC of the Banana Pi M3 (A83T) cannot work when the new mode is not used.That's odd. The one in the Pine64 seems to work just fine, and yet there's only the new mode on the A64.
I spent 2 weeks on this problem. You may try it by yourself. -- Ken ar c'henta? | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/
