Armbian for OrangePi PC2, AllWinner H5

Something broke in USB in the last couple of days. I just updated to the nightly kernel etc. and the hub no longer worked.

We only provide testing images at the moment ... those are as is. If you want Debian -> DIY -> https://github.com/igorpecovnik/lib

 

Thanks,  unfortunately I am not capable of image DIY :blink:,  so I have to use the ugly Debian image from official website. 

 

For this image, it's better to install below two first before doing something.

 

1. ntp

 

2. locale 

 

Overall, PC2 is not impressive as a server,  $10 lite/$15 pc enough.

 

Neverthless, PC2 performs faster and better than PC when running desktop/android, but be careful: CPU gets very hot, heat sink is a must in my opinions.

OMG. Why don't you just use our Xenial? Bad software = bad / wrong experience.

Possible, but this looks like you are having not sufficient power supply. Are powering via USB perhaps?

Sorry I need to use Debian, My PC has been running Armbian Debian.  

 

I always think Armbian image much better than official one, unfortunately no Debian for PC2:(

Hi all, first time posting here :)

First, thanks everyone that contribute to Armbian for OrangePi PC 2. This is my first time trying Armbian & so far it seems reliable! Running on nightly Desktop 4.10 .0 ( ARMBIAN 5.27.170331 nightly Ubuntu 16.04.2 LTS 4.10.0-sun50iw2 )
Most of the time, I use this board headless tho... Main goal is for speedy NAS because of the onboard GbE LAN(I have raspberry 2 for NAS right now).

The iperf3 benchmark amazingly consistent at ~900Mbit/s! Never expected that fast for this kind of SBC.

 

Anyway, I have issues for the USB OTG not working at all, Tried it as USB Host, or USB Device(client), none of them doing anything. On OrangePi PC 1 (using the loboris image) that port can act as a USB Host which I can plug additional flash drive there :) .

 

and other question - after googling a lot, I'm still confused about the "video hardware acceleration" and "video HW decoder" - is it the same, or the latter is only for video codecs playing capability? Can someone explain briefly why this HW acceleration is only possible on Android because of Allwinner not releasing the (source code?) Can't we use the Android's binary/modules and use it on other distro?

 

once again, thanks a lot to those that make this amazing board running a really good software (not the crap one that xunlong created :D)

Hello,

did somebody find SPI flash usable? I am thinking about boot redirect to HDD on USB. Has anyone idea how to make that?

Thanks

Hello.

Maybe stupid question to ask here. Is Orange Pi Zero NAS compatible with PC2?
Thanks.

Yes it is but you need some soldering skills to connect to USB on PC2

Not exactly "usable", but possible to use.

First, write the u-boot (u-boot-sunxi-with-spl.bin located somewhere in /usr/lib/linux-u-boot-dev...) to the SPI flash, either with dd to /dev/mtd0block or with flashcp to /dev/mtd0. No offsets are needed for dd.

Second, write a fresh image to the USB HDD (i.e. using Etcher). Old images (even after upgrades) or installed with nand-sata-install may not work and were not tested.

Third, shut down the board, remove the SD card, power it on and hope that your HDD spins up fast enough. U-boot has a timeout for detecting USB devices that AFAIK can be changed only with recompilation and if HDD spins up long enough it won't be detected.

 

If there are any issues, they will not be looked into without a log from the serial console.

Yes, should be either

dd if=u-boot-sunxi-with-spl.bin of=/dev/mtd0block

or

flashcp u-boot-sunxi-with-spl.bin /dev/mtd0

flashcp is present in the "mtd-utils" package

Thank you very much! The flashcp made the work. I didn't know to what package is this utility included, since that dd did nothing. Thanks again.

I just received my Opi PC2 and set it up with the latest nightly build (no desktop). I chose the PC2 because of the Gbit ethernet adapter as I want to use it as a file server for my LAN. After setting it up with a samba share to the connected USB 2.0 2.5'' HDD I only get ~11.7 MB/s download rate via ethernet. That's even slower than my old Atom N270 based netbook with only a 100Mbit LAN adapter which I used before with the same USB HDD.

I connected the Opi PC2 via a Gbit switch and directly to the router. I tested it with my main PC and a Lenovo Thinkpad to make sure it's not an issue with the ethernet adapters or the switch. It's always around 11.7 MB/s which is more than disappointing for a Gbit SoC. CPU load and temperatures are low during the transfer, so it's not a heat / throttling issue.

 

Anybody running samba on the Opi PC2 with better results?

PC 2 currently receives zero optimizations (well, still not officially supported). There's something like IRQ affinity, there are some tweaks regarding IO scheduling, some regarding ondemand cpufreq governor and also some smb.conf tweaks.

 

You might want to read through 

And then try it again, watch /proc/interrupts later, have a look in /etc/init.d/armhwinfo and add 2 or 3 lines to /etc/rc.local to distribute eth0 and usb IRQs accordingly.

 

First steps are alway testing storage individually (no dd, no hdparm but iozone instead) and network individually (iperf3)

Looks like your network is running in 100Mbit mode.Check if you can negotiate gigabit speeds on the network card, then you should hit better speeds (still ultimately limited by usb2)

I was thinking the same as 11,7MB/s sounds a lot like 100Mbit. But ethtool says otherwise if I'm not missing something.

USB HDD benchmark with iozone (1 thread, 1GB file) also looks ok. Or should I worry because of the lower random read / write values?

Yep, H5 boards with Gigabit Ethernet are known to exceed 930 Mbits/sec (more than 945 MBits/sec is impossible). Ethtool only tells what both partners negotiated but not what's really possible. Would be interesting to use iperf3 with UDP.

Well, that's Fast Ethernet and unrelated to OPi PC 2 (so I hope an admin will move these posts to a splitted off thread to keep the thread focussed on OPi PC 2). No idea what's going on (since ethtool reports a GBit link) but obviously there's something in the chain that is Fast Ethernet only. I would assign fixed IP addresses (not really, I'm using macOS and there it's not necessary since Bonjour does the job) and connect both devices directly (GbE supports Auto MDI-X so no need for 'cross-over' cables any more).

You're right, it was a networking issue with one of my Gbit switches which I didn't notice before. It's running fine @945Mbit now, Samba file transfer is around 33-35MB/s which is the USB 2.0 limit of the HDD.

Sorry for that. Would be nice if an admin could clean up this thread a little.

Can anyone could make a test with speedy SDCard on PC2?
Since it has SDIO 3.0, I really wonder it's SDCard performance with SDcards with 90MB/s speed.

Actual sd card slot is still limited to SD25, so you won't see anything like 90MB/s. Not that it matter, because responsiveness is determined by random performance, not sequential.
