Armbian for OrangePi PC2, AllWinner H5

Question

Hi,

 

Are there any news on if Armbian will be on the new H5 64bit board?

Orange released an Android SDK and an Android image but I guess everyone is waiting for a decent 64bit Debian.

 

Since took the plunge and got into the H5 wagon ordering one, I looked at the released info and obviously there was nothing I could use myself..

So the question goes to the Armbian gurus, guys do you think that there could be an Armbian release for H5 this year?

 

Christos

In case anyone missed it, Mikaey posted a workaround that does not require a new armbian image / kernel. Perhaps a viable workaround?

 

I am not sure what the best fix is for armbian itself (so that it will be fixed in some upcoming release), so I don't feel confident submitting a pull request, but time permitting I will have another look this weekend.

I've already tried on my "probaly fried" OpiPC2 described earlier. It works. And it's funny. Since my temperature is about 80C due to h/w fault - Opi is throttled to 120Mhz permanently :). Atmega MCU can even compete with this. Anyway, workaround works. Not sure it will survive kernel update via apt (in case it won't be included into).

Is H5 actually safe to operate close to 105C? I see that the CPU shuts down only at 105C https://github.com/armbian/build/blob/8f4ab52b6ea806a69eec3f4ad7adbaeb5cd0f1b4/patch/kernel/sunxi-next/ths-29-add-correct-h5-thermal-zone.patch Is it not a bit too adventurous to allow operation at such a high temperature?


It should be fine.

"For reliability and operability concerns, the absolute maximum junction temperature of H5 has to be below 125°C"

The latest update on my OPI pc2 has reduced the max cpu freq from 1.3ghz to 1.01ghz.

 

I believe the old minfreq was 120mhz?

Use armbian-config and adjust those values.

Which was there by mistake. Going below 480 has a drastic impact on performance, while consumption is virtually unchanged.

Hope you like the photo and idea of modifying for a fan.  It's gruesome but effective.  There are several Pi-FAN for sale but for some reason none of them, i found, have the CFM the ones from the acrylic case I bought from DIYzone store on ALIExpress.  Been meaning to ask them if they sell just the fans he obtains.  Other PI-FAN(Manufacture label), I have bought, are inferior and the CFM is less then the breath of a Kitten in a full slumber and about as quiet.  8-/  Maybe they just need to break in?  https://www.aliexpress.com/item/32621151739.html 

 

These acrylic cases need to be hot to the touch before assembly. Very stiff acrylic.  They have powerful loud fans though!

I have updated to Armbian 20.02.1 from 20.02.0-rc1 on the orangepi PC2 and can happily report that the issues with the wireless autentication failures present in RC1 have been resolved for .1 and now function correctly as it was in the past. 

 

CPU temp and Frequency displays in HTOP also working correctly. 

 

Very pleased to also see the lima drivers in the kernel - will be reviewing how to test. 

 

Thank you for all the hard work - it is appreciated!

Great work! I have the same problem with a PC 2 which came direct from the manufacturer

 

Your script has some unicode characters so I removed them:


sed -i -e '1imw.l 0x01C20020 0x80101810\' /boot/boot.cmd
mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

 

 

Great find - I also have some instability issues with my OrangePi PC2 (especially in load situations (like extracting an archive)).

How can I check the current DRAM PLL value so I know if this fix would help me?

Until now only reducing the clock speed seems to work.

 

Thanks!

Hi everyone

I've been following the comments for H264 HW Encoder on Allwinner H5.

it seems it isn't supported by recent mainline kernel any more. 

any body knows there is a driver for H264 Hardware Encoding on Allwinner H5 or it is still in progress ?

I don't know if is part of the bootlin effort included in past crowd funding related to H3 encoding.

 

Thanks for your comment @manuti.

I've read the report of the last crowd funding of booltin. it seems the encoder part of Allwinner H5 remains undone.

so then I haven't found any other news expect that uboborov's sunxi cedar mainline for Allwinner H3 on legacy kernel.

Now I don't know whether there is an hardware encoder driver for H5 or not?
