[Volunteer needed]Too high DRAM clock speed MAY be causing you random crashes/freezes

[gotomech]

@devrtz do the instructions in OP still work in newer builds / nightlies?
Flashed more than one PinePhone and always end up with white LED and no boot.

For reference:

Code:

sudo dd if=u-boot-sunxi-with-spl-600.bin of=/dev/sdg bs=8k seek=1

I just flashed the latest image I had built (492MHz) and it boots with the instructions from the OP. Do you have a serial connection handy to check where it hangs?

You may want to try this image:
https://fortysixandtwo.eu/upload/u-boot-...pl-492.bin
It is the latest one I built. But be aware that deep sleep didn't seem to be working for me.

Sidenote:

I think "u-boot-install-sunxi64" should be used nowadays to update u-boot in mobian. Not sure if you can just replace the binary in
"/usr/lib/u-boot/pinephone/u-boot.bin" then run "u-boot-install-sunxi64 /dev/XXX" and have it working..

Maybe I should look into building a .deb file. I think in this case the postinstall scripts take care of everything!

I've definitely gotten a lot of hangs recently too, though it usually happens if they don't have a specific boot partition or they have swap or unformatted section at the front of the sd card.

Also, I need this to be a far more prominent thing, because everyone wants that extra performance, and I'm definitely one of the unlucky people whose memory cant do over 500MHz...thankfully there only seem to be a few of us.

@lukasz are you guys at pine64 gonna try to weed out the really bad samples in the future, or should there we a bigger press to distro designers to make memory overclocking an after install rather than built-in thing?

I'd love the performance, and I'm glad that it's there for those that can use it. However, especially with phosh, those memory crashes are brutal and consistent.

Also, love the idea @devrtz , definitely let me know if you get that going. I'd love to do more testing with other memory clocks in mobian!
