rock64, compile problems "illegal instruction", "memory fault" -> ddr_333Mhz?
#4
Hello,

  400 and 600 Mhz are not working with dfi/dmc in rk3328-rock64.dts.
Patching  them into rk3328_ddr_333MHz_v1.13.bin  will give me some obscure 928 Mhz frequence,
that won't reboot stable.

786 Mhz (sic!) boots, but will give me segfaults or illegal instruction when compiling.

333Mhz is shown in grep '' /sys/class/devfreq/dmc/* as 332000000 and is stable compiling.

But I found a negative implication:  Playing hevc in 720p forces framedropping in mpv.

So either compiling stable or viewing fluid videos.
