How to enable i.MX6 IPU active window setting.

Hi community,

Our partner have a question about i.MX6SDL IPU.

Please see chapter 38.4.10.3.4 in IMX6SDLRM Rev.1.

It says "The DI provides an alternative way to define the synchronous display setting by using an active window and thus, needs to program less counters.".

However, we did not find how to select which way.

Could you let me know how to enable active window setting?

Best Regards,

Satoshi Shimoda

Hi Satoshi

I am afraid there are no such examples.

For counter programming examples one can look at

linux sources

linux/drivers/mxc/ipu3/ipu_disp.c

Hi igor,

Thank you for your reply.

According to your reply, there is no register to select active window method, and it is set by software.

Is this right?
