What processor are you using?

If you're using i.MX6, you can use this code to test CSC.

https://github.com/rogeriorps/ipu-examples/blob/master/mx6/csc/example1/csc_ex1.c

It will read 4 files from different color formats and transform to RGB565 to be shown on lcd.

Hi John,

If you're using i.MX53 you have 2 options. You can use IOCTLs as made on example I mentioned or you can use the ipulib. (see the imx5x_IPU_LIB_UG.pdf, located at linux documentation package.

You can check the ipu unit test, located at your rootfs /unit_tests/mxc_ipudev_test.out

The source code can be extracted using LTIB using the command:

./ltib -p imx-test -m prep

The source code will be located at ltib/rpm/BUILD/imx-test-12.09.01/test

Hi,

Rogerio

I am using IMX35. Does IMX53 IPU code works on IMX35?

I'm not sure if the same source code will work because they use different drivers. i.MX35 uses IPUv1 instead IPUv3.

You can check and use as programming reference the /unit_tests built on your rootfs/unit_tests/

Can you send me IPU test for YUV to RGB for IMX35?

Thanks

You can extract the unit test using the command: ./ltib -p imx-test -m prep

It will be extracted to <your ltib folder>/rpm/BUILD/imx-test-09.12.01/........

You can build and install this package using:

./ltib -p imx-test -m scbuild

./ltib -p imx-test -m scdeploy
