We want to implement ftrace function in L3.14.28 Linux BSP.
(bb file is based on the fsl-image-gui.bb)
However I cannot enable the ftrace function.
Would you tell me how to enable the ftrace function?
We refer to the following URL.
We added the following line to conf/local.conf.
$ EXTRA_IMAGE_FEATURES = "debug-tweaks tools-profile"
$ PACKAGE_DEBUG_SPLIT_STYLE = 'debug-file-directory'
And then bitbak is executed.
However, tracing folder is not made under /sys/kernel/debug/.
We suspect that a procedure is not enough.
If there is the package which should be added to IMAGE_INSTALL_append more, would you tell us it?
On the other hand, we exclude the following item from IMAGE_INSTALL_append
May we have any advice?
