2008-02-29 15:41:05     IPIPE tracer in 2008R1-RC1


Message: 51923    Hello,


I am trying to get a combination of Xenomai/Adeos/uclinux 2008R1-RC1 running the Xenomai Latency testsuite program on a BF537 stamp board with the Ipipe tracer tool.  I have included the combination of releases I am using at the end of this message.

I am following the Xenomai installation instructions from: http://docs.blackfin.uclinux.org/doku.php?id=linux-kernel:adeos


With the previous assistance from Yi, I was able to get the latency program to run by adding txenomai/lib directory to the LD_LIBRARY_PATH and the latency program of the testsuite is running.

The problem that is occurring now is that when you choose the options in linux_menuconfig specified by the appnote

listed above to enable the Ipipe tracer:


<pre class="code">--- Kernel hacking

[*] I-pipe debugging

[*] Check for illicit cross-domain calls

[*] Latency tracing

[ ] Enable tracing on boot

[*] Instrument function entries

[*] Trace IRQs-off times

(14) Depth of trace log (14 => 16Kpoints, 15 => 32Kpoints)

[ ] Use vmalloc'ed trace buffer

[ ] Enable panic back traces


You get a build error when building the kernel:


make[2]: *** No rule to make target `arch/blackfin/kernel/mcount.o', needed by `arch/blackfin/kernel/built-in.o'.  Stop.

make[1]: *** [arch/blackfin/kernel] Error 2

make[1]: Leaving directory `/home2/dhecht/UCLINUX/2008/R1-RC1/uClinux-dist-2008R1-RC1/linux-2.6.x'

make: *** [linux] Error 1


I am using the following:


Xenomai 2.4.0


Any help you can offer would be greatly appreciated,

Message: 51928    looks like the newer adeos patch does not include the mcount source file ... you can probably cheat and just take the ipipe-mcount.S from the older patch and name it mcount.S in the kernel file until Yi gets a chance to do so

Message: 51988    Should have been fixed in 2008r1 svn branch.


(I was using "svn diff" to create patch, new files will get lost if not run "svn add". I turn back to use "diff").

Message: 52059    Yi,


Thank you very much for your help.  After I downloaded this version, everything compiled fine.  We had a few more problems with the stamp board freezing when booting the kernel but I saw that this was due to our limited memory.  When I deleted the xenomai/share and xenomai/include directories from the romfs, it made a huge difference and things seem to be working now.


Thank you so much for your quick response.


best regards,
