[Xenomai-help] Sudo not found when running the latency test

Hi,

We're using an embedded system, the Virtex2pro from Xilinx (XC2VP300). This
chipset includes 2 powerpc's (ppc-405) and a FPGA. We're running a linux
kernel from denx (20060707) patched with 'adeos-ipipe-2.4.25-ppc-CVS-
20060707-1.1-04.patch '. We got the linux kernel from denx with cvs:
        cvs -d :pserver:anonymous@domain.hid login
        cvs -z6 -d :pserver:anonymous@domain.hid co -P -D 20060707
linuxppc_2_4_devel
We got xenomai with svn:
        svn co svn://svn.gna.org/svn/xenomai/branches/v2.2.x
xenomai_branches

With the Xilinx software (EDK 8.1) we built board support packages for the
kernel.  We use the crosstool from
<http://kegel.com/crosstool/#download> to build the ppc crosscompiler.


We build the rootfilesystem with the busybox_1_1_stable release. We got the
following error when running the latency test: "./run".

*
*
* Type ^C to stop this application.
*
*
/usr/xenomai/bin/xeno-load: /usr/xenomai/bin/xeno-load: 249: sudo: not found

If we run "./latency", no error occurs.

Did we forget something obvious?  What would be the best way to debug this
situation?  Any hints are welcome!

Best regards,

Stefan De la haye & Steven Kauffmann

It's a bug in the xeno-load script for the benchmarks which prevents the
execution over busybox. Fixed in the 2.3 branch, maybe we should
back-port it.
