Hi, I found some minutes to run a quick test with 4.13-rc5. I just increased kernel SMPS6 setting to 1.5V and changed nothing else.
It does still not boot very well.
I see on first attempt:
[ 2.613219] smps6: Bringing 1350000uV into 1500000-1500000uV
but it has no visible effects before or after.
From what I understood from Tony, you need the termination and interleave settings too to get any improvement (3 u-boot patches sent today).
Correct, so far it seems all three u-boot patches plus the related kernel dts patch are needed.
