working on a Nokia N800 --- Thanks to the good work by Barbieri, I've gotten oprofile installed and running on my N800. QUESTION/PROBLEM: Daemon now reports an "Invalid argument" problem opening the output files: oprofiled: open of /var/lib/oprofile/samples//current/{root}//bin/busybox/{dep}/{root}//lib/libc-2.3.6.so/CPU_CYCLES.10000.0.all.all.all failed: Invalid argument This apparently happens many times .. the oprofiled.log contains 53K lines, after a really brief run of a simple program. ALSO - it has created quite a few of these files, notwithstanding the error HOWEVER - the files ALL have only null data -- in my case, size 2680 with all bytes 0 (same for all files!) --> which, naturally, leads to an unhappy result with opreport, which complains of "Invalid argument".. --- NOTE - it did work for a while last week. (I don't recall changing any configuration parameters) I've tried reinstalling the SDK filesystem and oprofile things, but no improvements. Runs are made with /var/lib/oprofile -> /home/user/runs/oprofile, lots of space available on main file system, empty "oprofile" directory to start with. Any suggestions would be most helpful.... -------------- next part -------------- An HTML attachment was scrubbed...
