Plugins can be created for any trace format to allow its conversion to/from another trace format. Babeltrace is the reference implementation of the Common Trace Format (see ). Babeltrace can decode and display LTTng traces, since the latter are written using the CTF format. Having this tool on the target is not mandatory. You can transfer the binary trace output from the target to your development workstation, and use babeltrace here. Buildroot automatically builds a host babeltrace in $(O)/host/usr/bin/babeltrace as a dependency of the lttng-tools package. http://www.efficios.com/babeltrace comment "lttng-babeltrace needs a uclibc snapshot or (e)glib toolchain w/ wchar, threads" depends on BR2_USE_MMU depends on !BR2_USE_WCHAR || !BR2_TOOLCHAIN_HAS_THREADS \ || !(BR2_UCLIBC_VERSION_SNAPSHOT || BR2_TOOLCHAIN_USES_GLIBC)
