This was already answered couple of days before.
For now, firmware loading only works on Ubuntu 14. ...

it works on :

WiringOP a GPIO library for Oangepi PC/ Plus is released for testing. Click link below.

Click Here ...

A small reference to me would have been nice

Adaptation to H3 orange pi was made by me.

Next Time please

Tested OrangePi Plus 2 with laboris Kernel and 14.04 Lubuntu.

Wow, I'm excited. 2GB Ram make the difference. A speed boost.
Even with chromium, there is no kswapd0 -Problem more

hdparm -tT (SanDisk Ultra)-> 488 MB, 20 MB
hdparm -tT --direct -> 21,5 MB, 21,6 MB

hdparm -tT (intern mmc) -> 501 MB, 57 !! MB
hdparm -tT --direct -> 68 MB, 69 MB

what a power Boooosssttt

Wlan (with wicd!, disable network manager), Ethernet, Sound (hdmi, analog) USB, 1Wire , WiringPi.... everthing OK

save this code to some script and make it executable.

Works fine Thanks! I made a little modifications.

#!/bin/bash
Color_Off='\033[0m'
Red='\033[1;91m'
while :
do
clear
T1=`cat /sys/devices/virtual/hwmon/hwmon1/temp1_input`
T2=`cat /sys/devices/virtual/hwmon/hwmon1/temp1_crit`
F1=`cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq`
F2=$[$F1/1000]
echo "――——―――———―――———"
if [ "$T1" -gt "$T2" ]
then
echo -e "CPU temp: ${Red}"$T1"${Color_Off}""°C"
else
echo "CPU temp:" $T1"ºC"
fi
echo "CPU freq: "$F2" Mhz"
echo "――——―――———―――———"
echo "Press Ctrl+C to finish"
sleep 1
done

Copy code

I don't take credit for this. I provided the original github source which contains the author's email. If the author is you, then kudos goes to you.

Hi,
I have question, how I should update kernel and libs currently? I should use update_kernel.sh script or manualy copy, paste? I think, script for uImage and script.bin work fine, but for lib I'm not sure, because it creates second folder 3.4.39-01-lobo in modules. What with test kernel (mali driver), update_kernel.sh "contains" it?
Thanks in advance for help.

Hello

Iam having a issue with kswapd0 process
I been using Ubuntu Mate for weeks now . Every think is so far so good but when my Pi 2 uses too much RAM kswapd0 uses too much CPU approx 100 % for hours even after RAM usage goes back to normal.

I had added a command in crontab that runs every 5 min. to clear the cache memory .
I also added swap memory of 2 GB and tested swapiness from 60 to 1 but none of that value helped .
After all that kswapd0 still uses 100% for 7-8 hours . As every time cron runs I have approx 700 MB free RAM and normally it have 500 MB . Most RAM using software I am using is JDownloader and copying files from mounted NTFS drive to a network drive . But when all these runs at once I get 100-200 MB free RAM . As my swapiness is set to 1 I do not think kswapd0 should use that amount of CPU.

As it is a kernal process it can not be killed . So is there anyway to stop this.

For kernel & script update use update_kernel.sh.
Newer kernels have version number included (3.4.39-01-lobo).
You can check with uname -a, and manualy delete the old directories from /lib/modules.
I'll add the version checking to update_kernel.sh soon, so that you'll be informed if newer version exists.

Hello

This is known Ubuntu (Linux) problem even with newer kernels and it is not OPI related.
I don't know any better solution for now.
If you are using samba, you can try to tune some cache and memory settings ...
