i.MX6SX display availability

[torus1000]

Hi,

I want to confirm i.MX6SX chip capability and linuxBSP supported feature.

i.MX6SX has 2 x LCDIF and each of it can drive LCD1 or LCD2 independently but there is only one PXP.

(Q) Can PXP handle 2 frame buffer simultaneously?

(Q) If not, can ARM/GPU update rest of frame buffer without PXP?

I usually use LVDS panel with i.MX6SX-SDB.

(Q) Does linuxBSP for this support dual display feature?

I guess linuxBSP only supported same screen for both LVDS and LCD1.

(Q) If possible, how can I configure 2 different screens for LVDS and LCD1?

Can anyone help me?

Q. Can PXP handle 2 frame buffer simultaneously?

A. Primarily, the Pixel Pipeline (PxP) module is intended to combine two frames (e.g. image frame and graphics surface frame) on the pixel-by-pixel basis. So, if the PxP performance allows, it can process two frame flows on frame-by-frame basis.

Q. Does linuxBSP for this support dual display feature?

A. Yes.

Q. If possible, how can I configure 2 different screens for LVDS and LCD1?

A. First, you have to configure the image output interfaces as described in the "video on 6SABRE-SD" row of the Table 11 in attached i.MX Linux Release Notes document. Then, you have to use Gstreamer as described in the Chapter 7 "Multimedia" of attached i.MX Linux User's Guide document.

Have a great day,
Artur
