BTSync does not run on Sheevaplug

[knireis]

BTSync does not run on my Sheevaplug running debian wheezy. I use Tuxpoldo's package. It installs fine but won't run.

 

Troubleshooting gives:

root@lisse:~# /usr/lib/btsync/btsync-daemon --nodaemon --config /etc/btsync/user.sierink.conf; echo "Return value: $?"Alignment errorReturn value: 1

According to Tuxpoldo this is due to an incompatible CPU.

 

Cpu info:

root@lisse:~# cat /proc/cpuinfoprocessor       : 0model name      : Feroceon 88FR131 rev 1 (v5l)BogoMIPS        : 1191.11Features        : swp half thumb fastmult edspCPU implementer : 0x56CPU architecture: 5TECPU variant     : 0x2CPU part        : 0x131CPU revision    : 1Hardware        : Marvell SheevaPlug Reference BoardRevision        : 0000Serial          : 0000000000000000

Any change of fixing this?

Additional info for the developers: the installed btsync binary is the one for ARM cpus.

Please execute 
echo 2 > /proc/cpu/alignment

and BTSync should work.

Thanks!

Hi Vadim,

one question: do you think I should include a check for the alignment and automatically fix it in my deployment scripts or do you think this will have some side effects?

Yes, it works, thanks

Is this a one time thing or is it needed after a reboot?

Unfortunately this has to be set at every reboot. That's the reason why I'm thinking about creating a possibility to set it also directly on btsync startup. But as a workaround if you are using the btsync server packages, you can add the line to the /etc/default/btsync configuration file:

`which sudo` echo >> /etc/default/btsync`which sudo` echo 'echo 2 > /proc/cpu/alignment' >> /etc/default/btsync

There are nome interesting articles about the alignment problem:

It may affect the performance of the other applications in the system. Not sure that it's good idea.

Thanks!
