Update Xbian Rpi2 to Rpi3 with xbian-config

[howdy]

Hi guys,

Im using xbian for a couple of months and im very happy, running also my Openhab stuff on it.
So, its getting time to test the new RPi3 with the config I have.

Newest 16.0 xbian installation.

I took my SD card with overclocking deactivated in xbian-config and test it with the Rpi3, works well!

So is it possible to update the Xbian environment to the new hardware seettings from the Pi 3 with xbian-config?
I use the preliminary setup with another SD card which is running fine with 1,2Ghz.
But then I ran in trouble to setup Java, openhab etc.
Burned some hours last night with that...

I'd like to avoid a new setup, because I took a lot of effort in installing java, openhab etc. stuff.

I'm happy to get some advice!
Cheers

what do you mean with "hardware settings"?
There is no difference between Rpi2 and Rpi3, only just a note: please leave your fingers from overclocking

You already answered your question by yourself:

You took your Rpi2 card into Rpi3 and everything is working. So there is no need do do a fresh install. I did the same

Hi Nachteule,

but when I have a look in system profile in Kodi it says 900Mhz, in case of using my old sd card.
After updating it decreases to 600 Mhz.

I dont understand whats going on.

If CPU is idle clock should be 600 MHz, otherwise 1.2 GHz

Ok, interesting. Do you know the difference compared to the preliminary build?
There are always 1,2Ghz shown in system profile.

It obviously has more power in using the Live tv addon Iptv simple client.
So its possible to switch Hd channels without crashing Kodi.

Difference is only the kernel (package)

What's the current version?
Now i have 4.4.6+

But I see some power issues, when I boot, the rainbow box is showing up.
I will buy a new usb power supply with 2,5 A

So then perhaps I have 1,2Ghz possibility?

Look at:

Terminal

sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq

(Max frequency allowed)

Terminal

sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq

(Idle frequency)

Terminal

sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq

(Current frequency)

So

Terminal

watch -n 1 cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

will show the current frequency of CPU0

If you use

Terminal

top

and then press "1" it will show each CPU, so choose one that is under load.

If you want to force some CPU load, install stress.

Terminal

sudo apt-get install stress -y

and then run

Terminal

stress -c 1 - t 10

will stress CPU 0 for 10 seconds.

or

Terminal

stress -c 4 - t 10

will stress all CPUs for 10 seconds.

Thanks for help!

My request says in a Rpi3 with Kodi 16.1, Kernel 4.4.6

cpuinfo_max_freq: 900000
cpuinfo_min_freq: 600000
cpuinfo_cur_freq: 900000

@howdy

Please show me your /boot/config.txt

[howdy]

#initramfs initramfs.gz 0x1000000
gpu_mem_1024=320
gpu_mem_512=144
gpu_mem_256=100
initial_turbo=3
hdmi_ignore_cec_init=1
disable_overscan=1
disable_splash=1
dtoverlay=lirc-rpi
decode_MPG2=xxx
arm_freq=900
core_freq=250
sdram_freq=450
over_voltage=0

This is the old setting from the Rpi2 still running.

[Nachteule]

No wonder that you're only getting 900MHz

please remove (or comment them out)

Code:

arm_freq=900
core_freq=250
sdram_freq=450
over_voltage=0

and after reboot you'll get 1.2GHz

[howdy]

Ah great!
I will try

[IriDium]

Looks like someone changed the config from the normal xbian settings. The figures seem to suggest Raspbian "Moderate" settings without the overvolt.

Would it be possible in the upgrade to show a warning, something like smb.conf where it asks users if they want to use the current configuration or accept the defaults - might help in the future.

[Nachteule]

Most guys (like me ) usually does not recognizing warnings and ignoring them
