    km1kze got a reaction from teenytinycactus in Orange Pi Zero Plus2 H5 hardware oddity in VDD_CPUX power circuit   
    Don't remember what was written on them, but if you bought from my link, they're good 
     
    You can also see a J1 marking on the original mosfet from the orange pi zero H2+

    km1kze got a reaction from 5kft in Orange Pi Zero Plus2 H5 hardware oddity in VDD_CPUX power circuit   
    The mosfets arrived and finaly managed to make a test, and it works! Thank you again 5kft !
     
    For me it worked with this Armbian version: Armbian_5.34.171121_Orangepizeroplus2-h5_Ubuntu_xenial_next_4.13.14.img, then compiled  with the build compilation tips shown by 5kft  in a previous post. It seems it runs at 1296 Mhz from the start, I didn't need to update cpufrequtils.
    Surprisingly, it stays in idle at a lower temperature than before. Idle now is 38 celsius -although with a temperature meter is around 45. Before it was 55 - real it was with 2-3 degrees more (ambient temperature around 25).

    I very much hope that those BSN20s will work - I bought mine from that very same seller 
     
    Regarding increasing the clocks, I've attached a subset of my test patchset for the current mainline sunxi-next kernel (4.14.y) that you could start from.  Hopefully you should be able to just copy this to your "armbian/build/userpatches/kernel/sunxi-next/" directory, then build your kernel as normal (e.g., "./compile.sh KERNEL_ONLY=yes KERNEL_CONFIGURE=no KERNEL_KEEP_CONFIG=no BRANCH=next BETA=yes BUILD_KSRC=no BOARD=orangepizeroplus2-h5").  Note that you'll need to update your "/etc/default/cpufrequtils" configuration to set the new min/max speeds (don't forget to reboot or restart the cpufreq daemon after doing this).
     
    When you do the build, make sure the patch step succeeds - the "z" at the beginning of the filename helps ensure that it is the last patch applied.
     
    (Note also that on reboot the HDMI driver crashes on my Plus2 - as a temporary workaround I disabled HDMI in the DTS as well.  Also I noticed that the default Armbian OPi plus2 patchset adds the regulator entry - I was confusing this change with my Neo Plus2 patch for this.)

    I've attached it here as a zip file, hopefully that will work
