The ltt-control is compiled properly and my linux krenel(omap3evm) is also patched and compiled correctly. When I finally loaded everything and call ltt-armall.sh to activate tracing, it doesn't work. I check the directory /mnt/debugfs/ltt. there is only kprobes subdirectory, the subdirectory markers required by ltt-armall.sh doesn't exist. Do i miss some steps?

A few things to check:

Make sure your LTTng and ltt-control versions match (see the
compatibility list on lttng.org).

Make sure all the ltt modules are loaded.
