I think you can take the i.MX unit_test for reference. There is an test example for ipu.

You can extract the package by this LTIB command.

./ltib -p imx-test -m prep

Then you can find the source code be extracted in ltib/rpm/BUILD/.

Hi,

Jimmy

Thanks for your reply.

I have build imx-test.

./rpm/BUILD/imx-test-09.12.01

It build for IMX35_3STACK.

I have port customized file system to IMX35.

But no IPU device is available in my kernel, so i need to enable that.

Can you please suggest me what changes is required to enable IPU in kernel and

fixed ipulib.shm issue.

Thanks,

John
