supported display resolutions for iMX6 solo/dual lite?

We have an LCD display which runs at HD resolution of 1080x1920 interfaced via MIPI. Currently it's connected to an iMX6 dual core processor via a parallel-to-MIPI bridge (because the iMX6 MIPI interface does not support the LCD's display resolution). Our testing has revealed that we only need a single processor and have disabled one of the cores to save on power consumption. To save on costs, I'm looking at the solo or dual-lite chips to see if they could be used for our purposes (they are pin-compatible, according to the feature set).

According to the product summary pages for both solo and dual lite;

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6DL#

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6S

both chips only support display resolutions upto 1366x768 (thus, not suitable for my purposes).

But, according to the "iMX6 Solo/Dual lite Applications Processor Reference Manual" , section 38.1.2.1.2.2 Display Interface (pages 2793 - 2795) mentions,

For synchronous access with one cycle/pixel, this enables, e.g (including 35% blanking

intervals)

1080p (1920x1080) @ 60 fps

2794

i.MX 6Solo/6DualLite Applications Processor Reference Manual, Rev. 1, 04/2013

Freescale Semiconductor, Inc.

Chapter 38 Image Processing Unit (IPU)

• WSXGA+ (1680x1050) @ 60 fps

• The combined rate for the two ports is up to 240 MP/sec

The interface includes the following additional features:

• Screen size: up to 4096 x 2048 pixels, programmable by software.

• Scan Order: progressive or interlaced

• Synchronization

• Programmable horizontal and vertical synchronization output signals (for

synchronous access)

• Data enabling output signal

• Software contrast control using 8-bit programmable pulse-width modulation (PWM)

Two dedicated PWM outputs are provided

So, I'd like some clarity on this matter - do the solo/dual-lite processors support 1080 HD resolution? If not, what is the datasheet referring to?

Puzzled,

Abraham V.

Hello Abraham,

Yes, both the i.MX6S and i.MX6DL support 1080p

Hi SerigosSolis,

How to configure 1920x1080@60hz  programmatically ?

i have converted the disp0 signal to hdmi using tfp410 dvi convertor, now how to configure the setting for hdmi display.

in DTS or driver file.

Regards,

Sumanth

SergioSolis,

Thanks for confirming. :smileyhappy: I'm passing this on to my superiors.

Happy,
