Mathieu,

This is the version  Linux Trace Toolkit Trace Control 0.30-09112006. I
am running this on EVM board with an ARM processor. The trace toolkit
came with Montavista Pro 5.0 toolchain.

When I run the lttv -m textDump on the trace directory, this is the
output I get

[root at gt9szxw61 linux-2.6.18-051608]# lttv -m textDump -t
/opt/phild/trace30-5

Hi,

Which version of LTTng are you using ? This is normal with newer
versions, since it does not use XML event descriptions anymore, but uses
the linux kernel markers instead.
