HDMI On imx6 Dual lite

[imman]

Hi,

We are working on imx6 DL with chip version 1.1 and in HDMI.

We need stand alone code for testing the HDMI in imx6 dual lite.

We have another imx6q reference platforms and our code works on that platforms.

So we need the Difference between imx6q and imx6 DL with respect to HDMI.

or Provide us the Standalone code HDMI Code works on imx6 DL for reference.

We will use that code for our development..

We are testing 1080p on hdmi and the same code works on imx6q and if use it in imx6dl and clock is different we got then we modifed the clock

source now we got the clock 148mhz so clock also proper now but we HDMI  is not working still.

Please guide us how to fix this issue.

Thanks.

Which stand alone code are you using?

Hi ,

I have used the freescale SDK and tested the HDMI with 720p. the same reference i can take and debugging now in my code.

Thanks for your help.

Which imx6d board are you using?

From the imx point of view, there is no change between imx6Q-HDMI and imx6D-HDMI. So, I need to understand what are the hardware changes you've been facing.

Could you, please, point me the link where I can find the source code you've been using?

Hi,

There is no change in our custom hardware wrt HDMI between iMX6Q and iMX6DL.

We are using i.MX 6Series Platform SDK from freescale which can be download from the below link

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6DL&nodeId=018rH3ZrDRB24A&fpsp=1&...

Under Software Development Tools -> Snippets, Boot Code, Headers, Monitors, etc -> i.MX 6Series Platform SDK

Could you please check the SDK code in one of your iMX6 Dualite reference platform and let us know whether HDMI works.

Thanks

Suppose MX6DL no board level issue and the HDMI setting is same as MX6Q,

the HDMI failed work should cause by IPU setting or some board specific setting.

Please check with followed process:

1. Please check DI setting in GPR3, MX6DL only have one IPU.

2. Pixel clock, for 1080p60 the pixel clock is 148.5MHz，

and the pixel clock should enabled before HDMI PHY configuration.

3. Make sure clock hdmi_isfr and hdmi_iahb is enabled.

4. Please check other display such as LVDS panel can work in MX6DL platform.

If all above setting is right, please double check HDMI setting, dump the MX6DL and MXQ HDMI register  and compare it one by one.
