The New 4-core Raspberry Pi

[dwijtsma]

I have come to the following at line 208. Somehow I got the feeling that I should do something other that copy/paste the following to raspberry pi:
# ----->>>> BUILD CUSTOM PACKAGES <<<<----- #
# clone RuneOS repo
git clone https://github.com/RuneAudio/RuneOS.git /usr/local/src/RuneOS

Than I found this:
https://github.com/RuneAudio/RuneOS/blo ... uction.txt

I think this is the cookbook I should have used. I think I can fix this. (I hope )

Using my compare tool I now have followed the raspberry cook book. I have come to the point that it gets beyond my capabilities I'm afraid.
I have to download the RuneOS packages but the naming suggest it is for the armv6.
Can I ignore this or do I have a problem now?

If I will succeed or not, you also learn from failure.

I guess Runeaudio won't work if I don't instal RuneOS.
I guess I destroy arch linux if I do install the current RuneOS

If one of the two guesses is incorrect, please let me know. This evening I will look into the RuneOS files to see if I can make sense out of it. Hopefully I won't loose all hope!

Is it possible to make an .img file from it? Win32DiskImager works in both directions I believe. Like a temporary solutions till we have a nice maybe 0.4 version with everything working. If not, at least you gave me some hope. I think I can get it working if I put enough time in it. I like that I learn a lot.

Do you notice improvements with the pi2? Curious you see speed improvements. Can you play flac at very high bit rates for example?

I'm so thankfull for all the work done by ACX, Orion and everyone else working on it.

The Pi 2 not only has four cores where the Pi has one (more cores is in general a good thing for any multitasking OS), but it also runs at a higher clock speed and has more RAM. I don't know enough about ARM to know if the newer processor architecture has other advantages (more instructions and the like). At any rate, I would think that RuneAudio would still run better even if most parts of it were single threaded.

Hi all,

i made a RuneAudio image for the RP2.

The first tests look promising, it runs very smooth and the UI is incredible fast.

With a multi core processor one can do "cool" things.
For example isolating the last two cores from the scheduler and run MPD and other stuff exclusively on them.
Core 2 and 3 isolated and core 3 running MPD.

or
Core 3 isolated and running MPD, cores 0-2 loaded with stress testing software.

MPD plays without issues while the UI is nearly not accessible anymore.

If this will improve the audio quality?
