I have NFS running on opi PC2 5.4.43-sunxi64 working fine
-
I had a problem with ext4 and data being committed every 30 seconds and changing commit interval in fstab made no difference to fix it I modified:
/proc/sys/vm/dirty_expire_centisecs
to 500 (5 seconds). 30 seconds is default
You can monitor it with:
cat /proc/meminfo | grep "Dirty" -A1

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?
linux-stretch-root-next-orangepipc2_5.85_arm64.deb
/etc/default/cpufrequtils

I have a similar issue on opi PC2 with 4.19.25-sunxi64 and a DVB-T2 USB dongle. The problem is solved by locking the frequency scaling.
E.g. I have
# WARNING: this file will be replaced on board support package (linux-root-...) upgrade ENABLE=true MIN_SPEED=120000 MAX_SPEED=1400000 #MAX_SPEED=500000 GOVERNOR=conservativeIf MIN_SPEED and MAX_SPEED are the same you don't get any problems.
Performance gov works OK (it locks to max freq)
ondemand or interactive don't fix it unless you lock frequency
I can lock frequency at 420mhz and it works fine so it's not related to actual frequency
If I set MIN=800 and max=1300 it still gives problems
my error:

On the PC2 I found the default governor (ondemand?) makes the freq spike too much, conservative prevents it from just hitting max freq every time you load it.
I run conservative with an up_threshold of 50 (I think default is 25%)
IIRC the parameter that allows it to consider IO as part of the load is not available on conservative so you lose a small amount of performance at the top end. If you're using USB wifi dongles it also doesn't want to increase freq in a hurry when running conservative.

I have just noticed the same issue when trying to use armbian-config on pi pc2, as have others here:

I thought I'd share some links to JMS578 based enclosures I've found:
ACASIS FA-08US - cheapest on ebay but also on ali https://www.aliexpress.com/item/Acasis-fa08us-2-5-inch-usb3-0-aluminum-external-hard-drive-disk-SATA-SSD-mechanical-solid/32818921168.html
Metal enclosure with plastic tray, has 4 mounting holes to secure the drive to the tray. Firmware Version: v0.5.0.8
CHIPAL clear enclosure - Firmware Version: v133.2.0.2. This enclosure gave me errors after running fstrim with an ADATA SU650 but not with another SSD I have. It works fine with discard. The SU650 + fstrim works fine in the ACASIS enclosure.
JZYuan adapter - according the pictures on aliexpress it has JMS578 but I've not personally tested it

Mt76 based dongles should work. A6210 works OK for me. I get around 160mbit/250mbit on 5ghz AC
110mbit on 2.4ghz
Around £15 on ebay. Argos sell them for £30 but reduce to £20 on occasion
https://wireless.wiki.kernel.org/en/users/drivers/mediatek
The drivers are under active development https://github.com/openwrt/mt76/commits/master
some of the RTL8812AU yellow dongles from china come with RTL8812CU now. RTL8812AU perform bad even under windows so likely have poor design

So the problem was solved!
sed -i -e '1imw.l 0x01C20020 0x80101810\' /boot/boot.cmd mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scrThe reason of crashes was DRAM PLL value which seems too high for the boards I have.
Default DRAM_PLL value set by u-boot 2017.05+ is 624MHz. It seems not all board support this value.
I changed it to 600MHz by setting 0x01c20020 register to 0x1810 value (instead of 0x1910 set by u-boot) and there's no any crash anymore.
The script adds "mw.l 0x01C20020 0x80101810" line to boot.cmd and then compiles boot.scr.
After that u-boot will change DRAM_PLL value to a bit lower one to avoid crashes.
Thanks everybody who helped me to find a solution.
Special thanks to @znoxx for testing and logging
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 -

Not for $20 shipped, but with the -for me - cheap NAS case the NanoPi Neo2 LTS is a option.
The Neo2 is available with 512MB or 1GB of Ram and works fine inside the NAS-Case
(I got 2 of these combinations running over a year).armbian-support for the Neo2 (H5-CPU) is fine. HDMI isnt included, but with the NAS-case he has 2 USB 2.0-Ports, GBE,
a power-switch AND a proper Power-connector for a normal 12V power-supply
Neo2 LTS:

NAS-case:
https://www.friendlyarm.com/index.php?route=product/product&path=85&product_id=222
That looks neat and essentially gives me 3 USB ports as I would be using USB-SATA adapter anyway but it's $55 USD including shipping to the UK

sound good

I have an orange pi PC that I use as a simple NAS (NFS, smb, iscsi) and for openVPN occasionally but want something new with GbE.
What is the best upgrade that will give me 2 or more usb ports, GbE and a faster processor? With decent software support (
)? I don't need HDMI or wifi but it would be a plus
512MB-1GB RAM
opi zero plus?
opi PC 2?
Around $20 shipped ideally

My samsung evo 64gb went read-only recently (20 months old) and then would not boot. I copied to another card and ran fsck and all seems OK. I think the later evos were not as well made as the earlier batches.

I'd use this to get the HDMI output of your DSLR encoded (720p only)
https://blog.danman.eu/new-version-of-lenkeng-hdmi-over-ip-extender-lkv373a/
Then a raspberry pi or pi0 to do the hw h264 re-encoding
-
Not sure, but I don't think so. AFAIK you can only wake from IR or GPIO
You can buy RTC modules based on the DS3231 which have built in wakeup alarms that you can set and trigger a GPIO on the opi to wake it

If you want hardware accelerated decoding you need to use mpv or mplayer. I'm not sure if you can run multiple instances and all use VDPAU
edit: mpv segfaults if you open 2 instances

I have VDPAU working on TVout on the opi zero.
VDPAU only works on screen0. opizero is set to use screen1 by default, but both are configured to PAL/TVOUT. setting VDPAU_SCREEN=1 had no effect so I just changed the fex to: disp_mode=0

Thanks.
Desktop works but HW video decoding doesn't, I just get a black window - the same video works on my OpiPC.
Does VDPAU support TV out/CVBS?

I'm not having any luck getting an image. I've connected mine (same model as Neo) as shown in the first video.
If I don't connect the backlight (3v3) then the screen flashes faintly sometimes when using test programs. When the backlight is connected it doesn't appear to do anything - just a white screen
