Examples of using ipu in imx6

ipu-examples

IPU example codes for i.MX5 and i.MX6 families

Cross-compiling using Yocto Project toolchain:

Install the SDK generated by Yocto Project following the training topics below:

https://community.freescale.com/docs/DOC-95122
https://community.freescale.com/docs/DOC-95225

Export the Yocto Project variable running the SDK environment setup (don't forget the "source" command) The toolchain version will change according to it's version. It's usually installed at /opt/poky/......

$ source /opt/poky/1.6+snapshot/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi

Now, use configure and make to build.

$ ./configure --host=arm-none-linux-gnueabi --target=<target> --prefix=<prefix>

Where:
<target>: mx5 or mx6
<prefix>: local where your i.MX rootfs is

$ make

Cross-compiling using LTIB toolchain:

To crosscompile the ipu-examples, set the environment variables:

$ export PATH=$PATH:/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/
$ export TOOLCHAIN=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/
$ export CROSS_COMPILE=arm-none-linux-gnueabi-

Notes:

• Usually the TOOLCHAIN is loated at /opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/
  it may vary according to the tool you have instaled on your machine

Now, use configure and make to build.

$ ./configure --host=arm-none-linux-gnueabi --target=<target> --prefix=<prefix>

Where:
<target>: mx5 or mx6
<prefix>: local where your i.MX rootfs is

$ make

Available examples:

The project has the following folders:

bin : Generated binaries
images : Pictures used by examples
mx5 : i.MX5 family examples
mx6 : i.MX6 family examples

Inside mx5 and mx6 folders, there are the following folders:

alphablending : Alpha blending usage examples
basic : Basic examples like turn on/off cursor, fill framebuffer and etc
combining : Frame combining examples
cropping : Crop image examples
csc : Color Space Conversion examples
deinterlacing : Video de-interlace examples
doc : Documentation. Details about IPU and code implementation
others : Mix of various common use cases
resizing : Resize examples
rotation : Rotation examples
