You may use examples from Linux test package.
Test sources (of utilites in /unit_tests directory) may be found in imx-test and mxc-misc packages.
To get them under LTIB :
$ /ltib -c
Select
Package list -> imx-test
$ ./ltib -p mxc-misc -m prep
After that, <ltib>/rpm/BUILD/misc/test/ directory will contain the sources.
In particular, please take a look at <ltib>/rpm/BUILD/misc/test//mxc_sound_test
Note, test images may be found in <rootfs>/unit_tests directory.
Thank you for your reply.
I have got the answer.I am testing it know.
