Hello, After running BOINC with QCN and Radioactive@home projects on a Raspberry Pi, I see the ARM application for WUprop, but after the attach got this error: Host Project Date Message raspberrypi http://wuprop.boinc-af.org/ 03/01/2013 1.19.57 Master file download succeeded raspberrypi http://wuprop.boinc-af.org/ 03/01/2013 1.20.02 Sending scheduler request: Project initialization. raspberrypi http://wuprop.boinc-af.org/ 03/01/2013 1.20.02 Requesting new tasks for CPU raspberrypi WUProp@Home 03/01/2013 1.20.15 Scheduler request completed: got 0 new tasks raspberrypi WUProp@Home 03/01/2013 1.20.15 Message from server: This project doesn't support computers of type armv6l-unknown-linux-gnueabihf I'm run a custom QCN version of BOINC (7.1.0) If the admins needs, I can test a WUprop raspbian application.

I've actually compiled a version of data_collect and tried attaching using anonymous platform, however, it doesn't seem to be pushing data into WU out file. I have it running alongside a POGS attached project. I've sent the admin a private message. Hope to get a response soon... WUProp would be great for Raspberry Pis with other tasks.

I think I've figured this out. It looks like it relies on p_model in client_state.xml to be populated. When I forced p_model to armv61 it started working... I can see what NativeBOINC has done to resolve this. They wrote a seperate function that reads model data out of /system. I'll put something together and post back here. Hopefully the admin has a read and provides some feedback.

Sorry for late .... reading all post seems that is going out an official client for Raspbian ? My Raspberry is already attached so I think that when it will become available i'll see a fourth WU running together the QCN + Radioactive + Asteroids ones ?

Hello,

After running BOINC with QCN and Radioactive@home projects on a Raspberry Pi, I see the ARM application for WUprop, but after the attach got this error:

Host Project Date Message raspberrypi http://wuprop.boinc-af.org/ 03/01/2013 1.19.57 Master file download succeeded raspberrypi http://wuprop.boinc-af.org/ 03/01/2013 1.20.02 Sending scheduler request: Project initialization. raspberrypi http://wuprop.boinc-af.org/ 03/01/2013 1.20.02 Requesting new tasks for CPU raspberrypi WUProp@Home 03/01/2013 1.20.15 Scheduler request completed: got 0 new tasks raspberrypi WUProp@Home 03/01/2013 1.20.15 Message from server: This project doesn't support computers of type armv6l-unknown-linux-gnueabihf

I'm run a custom QCN version of BOINC (7.1.0)
If the admins needs, I can test a WUprop raspbian application.

OK, I've patched using this code:

I know the "uname -m" (which is essentially what this is) doesn't give as detailed info, but it's going to be there.

Just waiting for a task to finish so I can see if it validates.

You may need to add in the app_info.xml (e.g. after the line <version_num>339</version_num>):

<platform>XXXXXXX</platform>

(what to put in place of XXXXXXX I can't say, somebody running similar system have to check (search for <platform>) in his client_state.xml)

P.S.
Instead of "I've uncompress this file in the correct path" better post (copy) the real path here so people can check is it really 'the correct path'

Do you see in the startup messages:
"[WUProp@Home] Found app_info.xml; using anonymous platform"

Ok, found in client_state.xml and copy into app_info this line:

and after boinc restart it works! :)
Thank you!
Now my rasPi run 4 WUs (3 nci) and 1 full CPU, attached to 5 different projects (radioactive, QCN, asteroids, albert and WUprop), good job for a 5-watt-PC.

*Sigh* I just found out that in newer BOINC clients (e.g. 7.1.0) they correctly interrogate ARM CPU info.

There's no need for that additional code I added to the source to add platform info. Just upgrade the BOINC client.

Feel like an idiot...
