Orange Pi Zero Plus2 H5 hardware oddity in VDD_CPUX power circuit

Hi. The patch doesnt available. Is this correct?

 

Hi @rusatch - yes, however this is actually even easier to enable now; no patching and custom kernels should be needed ^_^  If you build Armbian from the latest top-of-tree for a sunxi device (starting with the 4.17.y kernel), two new DT overlays are provided that you can load via "/boot/armbianEnv.txt" that provide this regulator and will enable higher clock speeds to be used.  The original thread regarding this (with instructions) can be found here:  https://forum.armbian.com/topic/5051-nanopi-neo2-cpu-frequency-issue/?do=findComment&comment=58181.  I'll repeat these instructions here for others:

 

If you would like to try to run your board at 1.3GHz, and your board has a regulator on GPIO PL6 that supports 1.3v (e.g., Orange Pi Zero Plus2 H5 with Q5 MOSFET present, Orange Pi Zero Plus with Q5 MOSFET present, etc.), then all you would have to do is the following:

 

1.  Make sure that you know what you are doing (!).  If you enable the following on a board that does not properly have access to the CPU regulator - i.e., unmodified OrangePi board with missing Q5 MOSFET, or a board that does not have a compatible 1.1v/1.3v regulator controlled via GPIO PL6 - then your board will almost certainly crash on boot!

 

2.  Edit /boot/armbianEnv.txt, and add these lines:

overlay_prefix=sun50i-h5
overlays=gpio-regulator-1.3v cpu-clock-1.3GHz

If you have other overlays specified in your /boot/armbianEnv.txt, simply append these two new ones following them, for example:

overlay_prefix=sun50i-h5
overlays=spi-spidev usbhost2 usbhost3 gpio-regulator-1.3v cpu-clock-1.3GHz

 

3.  Edit /etc/default/cpufrequtils, and set the MAX_SPEED definition to 1300000:

# WARNING: this file will be replaced on board support package (linux-root-...) upgrade
ENABLE=true
MIN_SPEED=408000
MAX_SPEED=1300000
GOVERNOR=ondemand

 

4.  Reboot the board

 

That should be it!  Following reboot, you can verify proper operation at the higher CPU clock speeds using "cpufreq-info" (for example).

Ooh. With overlays its very usefull. Thank you very much. Its very cool! :)

Today i recieve mosfets from aliexpress, used link that was in this thread. Tomorrow i will include mosfet on board and try use overlays. :)

 

update: Found additional overlay named cpu-clock-1.4GHz. Is this experemental overlay?

This overlay sets the CPU clock frequency curve to 1.392GHz maximum; however it will only function if the board CPU regulator can support 1.4v output maximum, for example the NanoPi NEO Core2, which provides an I2C-based voltage regulator.  If you try using it on a board that only supports 1.3v maximum, then your maximum CPU clock rate would actually be limited to 1.2GHz.  So it should really only be used on higher-voltage capable boards.

whats the best price?
Got my first Zero Plus2 H5 (with 8GB eMMC) for GBP 13.99 + 11GBP Postage from Sweden - but via eBay at the 5th of June.

( Item No 112940564893 ).

On AliExpress its 23,90USD + Postage 

https://fr.aliexpress.com/item/Orange-Pi-Zero-Plus-2-H5-Quad-core-Bluetooth-mini-PC-Beyond-Raspberry-Pi-2-Wholesale/32801249806.html

 

I think about getting a second one from eBay (wouldnt use AliExpress from my CreditCard)

 

The Zero Plus2 H5 isnt running hot here as a headless-server - seems like a nice board.

When the build pauses for the kernel patch, edit ".../build/cache/sources/linux-mainline/linux-4.14.y/arch/arm64/boot/dts/allwinner/sun50i-h5-orangepi-zero-plus2.dts", and simply add a block for the LEDs (I added mine following the existing "wifi-pwrseq" block).  E.g.,

Save, and continue the build.  Then simply install the generated packages in ".../build/output/debs".  (It should also be possible to generate an overlay for this, but I haven't bothered to do this.)

 

Today I would update the "Kernel",  but now we have to edit 

.../build/cache/sources/linux-mainline/linux-4.17.y/arch/arm64/boot/dts/allwinner/sun50i-h5-orangepi-zero-plus2.dts

 

[EDIT] I did unfreeze my kernel and it updated from 4.14 to 4.17

LEDs are working and also reboot seems to work without creating/compiling my "own" kernel :)

 

So I am now at

ARMBIAN 5.57.180810 nightly Debian GNU/Linux 9 (stretch) 4.17.14-sunxi64

Linux opi-zero-plus2-h5 4.17.14-sunxi64 #23 SMP Sat Aug 11 01:00:21 CEST 2018 aarch64 GNU/Linux

Hi @guidol, yes I found with 4.17 that the HDMI-related shutdown/restart issues no longer occur.  I.e., you should not have to patch out these entries in the DT - it works fine by default (which is nice!).

Hi @guidol, very nice!  I am curious, if your board is new is it missing the Q5 MOSFET (next to the SD card slot on the bottom)?

So strange... oh well!  Thank you for checking!

Are there any new of these in the wild originally with Q5?

 

The seller from sweden does use a "standard" Picture which show the PCB with Q5 :(

PS: I have send a question to the seller if his newer boards include the Q5 voltage regulator....

I just received a Orange Pi Zero Plus without the Q5 voltage regulator. I purchased it a couple of weeks ago from the official Orange Pi store on Aliexpress.

Hi! Just wanted to share my experince.

I received Orange Pi Zero Plus and it was a board without Q5 FET soldered.

I could not find BSN20 FET, so I tried to check for an alternative.

 - First one to try and solder it was a SI2302 N-channel FET with marking A2SHB. This one was a failure. I could boot Armbian with nightly kernel 4.17.14, but  armbianmon utility showed "---" instead of the CPU clock. And I was unable to boot kernel with "gpio-regulator-1.3v" "cpu-clock-1.3GHz" overlays, it just hanged soon after loading kernel modules.

 - The second one I found was 2N7002 N-channel FET with marking K72-P2 (this one I salvaged out of an old MoBo). And it was a success! Board was able to boot with overlays enabled and it runs fine with clocks up to 1300MHz, yay! Now my board works just fine, but it heats like hell under stress, even with a good heat sink. Thanks that throttling works just fine too.

I think the diffrence in FETs is that we need one with lower Vgs threshold voltage than the one with higher drain current.

 

Hope this could be useful to somebody.

Thanks to everyone who made this tweak possible!

Thanks, 5kft.

 

I tried this MOSFET (https://detail.tmall.com/item.htm?id=42054287753&spm=a1z09.2.0.0.1d862e8dqfVd64&_u=kkr253ef31) with latest nightly release (Armbian_5.59.180815_Orangepizeroplus_Ubuntu_bionic_next_4.17.14).

After applied "gpio-regulator-1.3v & cpu-clock-1.3GHz"  overlays, my opi zero plus has been successfully actived 1296Mhz frequency. 

 

But if I boot my opi with default overlay(kernel 4.17.14), armbianmonitor shows "----" at cpu frequesncy column, dont know why.

Something is broken in the regard of DVFS on the modern kernel 4.17.y/4.18.y which we are trying to put together. Currently exploring what the issue is ... in the meantime I also consider reverting NEXT branch back to 4.14.y and leave it there for a while.

Thanks, Igor. But interesting, after applied 1.3v regulator overlay, the cpu frequency could be read correctly on kernel 4.17. It looks the modern kernel can only handle CPU frequency with voltage regulator. 

 

BTW, will the 1.3v regulator overlay still exist if you roll back to kernel 4.14? Thanks.

On 4.14.y DVFS generally works, but not sure if it works in all cases (board from the topic for example).

I have done a simple openssl benchmark for Allwinner H5 @ 816Mhz vs 1296MHz.

Just for all your information, I saw huge performance improvement @ 1296MHz.

 

Command: openssl speed -elapsed -evp aes-128-cbc

 

Thanks, 5kft bring us such useful information again.

Would someone please be kind enough to either point me to a post or some basic instructions on how to activate the higher frequency once I solder the mosfet into Q5? Is there a post on this thread which explains what I need to do? I have a Orange Pi Zero Plus.

Hello igor,

 

I've run apt upgrade today. It seems you have downgrade the kernel for opi zero plus to 4.14. Meanwhile the 1.3v regulator overlay was removed.

May I know how can I use the 1.3v regulator overlay on kernel 4.14 to boost my cpu frequency to 1296Mhz? Sincerely thanks.

You can't. You have to wait until is fixed, donate that we will be able to hire help or fix on your own ... which will be much faster.  You can also switch to DEV kernel branch, which should be the same as it was before your upgrade. 

 

And remember, nightly kernels comes without support. If they break, nobody will fix them on the spot.

Yes...+1 to what Igor said...  Unfortunately as much as I wished wasn't the case I don't have any spare time to help with this currently...  My advice right now is that you take a look at my overlay additions for these two overlays (in the DEV branch now) - they are very small - and you could try manually building them for your 4.14 kernel.  This should be fairly straightforward (e.g., take a look at "armbian-add-overlay" on-device).  I hope this helps - good luck!

Thanks, @5kft @Igor .  I have successfully switched to dev kernel(4.18). It looks everything is working like 4.17.

Edit: Sorry, had a massive brain fart and forgot to put the microSD card back in. It's working now :)

 

I'm hoping someone might be able to help me... I bought BSN20's from aliexpress here https://www.aliexpress.com/item/10pcs-lot-BSN20-M8W-SOT-23-new-original/32705392701.html?spm=a2g0s.9042311.0.0.16904c4dCoV0Uu

 

And soldered one to my Orange Pi Zero Plus board but now it doesn't power up. It was powering up OK before soldering the voltage regulator. Has anyone soldered one to an Orange Pi Zero Plus and did it work ok?

I soldered one of those on my board and it worked, but had some problems with 5v pins not giving enough voltage - but it boot up with no problems (I did the patching of armbian like it was presented in the first posts, by compiling it, etc.)

After I removed the mosfet the 5v pins were working as they should.
