With Android and Boinc 7.4.41 is cpu type for C2 reported correct:
http://universeathome.pl/universe/show_host_detail.php?hostid=46370

I have added aarch64-android-linux-gnu platform and copied Android app for it... We will see if this works with Android on Odroid C2.

NativeBoinc wasn't updated for new Android version (I think was compiled for Android 4.x libraries) and this can be reason...
I will ask its author for updated version :)

Odroid X2 with Debian Jessie get WU's without problems.

Have you check that both files has "boinc" as it owner?

O, there is two files:
http://universeathome.pl/universe/a/BHspin2
http://universeathome.pl/universe/a/app_info.xml

Download them and put i project folder on the machine which doesn't receive work (on my system it is /var/lib/boinc-client/projects/univeseathome.pl_universe/).

Then restart boinc-client.

JagDoc, can you try it now, please?


BTW, it is still 32bit application as I haven't 64bit ARM system, but it should work :)

Great :)
If it runs properly I can just add platform for your devices :)

I will do this tomorrow as is late now :)

Executable and parameter file (param.in) you will find in /slot folder in the machine which get WU's.
It should work on second system as well. Just run it in any folder by start executable file manually.

In BHspin2 WU's have to be send to the same architecture because 32 and 64 bits system have different precision in some double calculations and results files are not always identical...

Can it be that this is the problem for the server?
Odroid-C2 is 64 bit architecture with 64 and 32 bit Linux.
aarch64-unknown-linux-gnu with <alt_platform>arm-unknown-linux-gnueabihf</alt_platform> in cc_config.xml.

JagDoc, can you manualy run application (outside of BOINC folder with the same param.in file on both platforms, please?

I'm curious if application will work correctly and if results files have same content...

In BHspin2 WU's have to be send to the same architecture because 32 and 64 bits system have different precision in some double calculations and results files are not always identical...

The Linux is Ubuntu I suppose?

Can anyone confirm that BHspin2 or QuarkStars works on Android device?
If not - what is scheduler reply on your device?

On my Odroid-C2 with Ubuntu 16.04 (Amlogic ARM® Cortex®-A53(ARMv8) 2Ghz quad core CPU) i get :

Message from server: This project doesn't support computers of type aarch64-unknown-linux-gnu

You can try with a cc_config.xml like this:

<cc_config>
  <options>
        <alt_platform>arm-unknown-linux-gnueabihf</alt_platform>
  </options>
</cc_config>
