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).
