Hi All,
I would like to achieve dual display with clone mode using LCD (CLAA-WVGA, RGB666) and HDMI on iMX6Solo sabresd based custom board which uses the X11.
I have following doubts regarding dual display in clone mode
- Is dual display in clone mode supported using vivante xorg driver? or Is there another way to do this?
- Is this require some xorg.conf changes, can any one please share the same?
- Do I need to have same display configuration for both the display to achieve this (same resolution , same display timing etc..)
- Is there any modification require in kernel or userspace to achieve this?
Just to give some more information regarding my set-up:
I am using ipu and disp id 0 for both hdmi and lcd as follows and I observed errors from fb driver as following
ipu_id = <0>;
disp_id = <0>;
mxc_sdc_fb fb.31: ipu0-di0 already in use
mxc_sdc_fb: probe of fb.31 failed with error -16)
then I tried changing the disp_id to 1 as follows from 0 for hdmi and now kernel boots without errors from mxc_sdc_fb
I have HDMI at 1920x1080 or 1280x720 and LCD at 800x480 on di0.
I am using followings:
Kernel: https://github.com/wandboard-org/linux/tree/wandboard_imx_3.10.17_1.0.0_ga
Vivante GFX drivers: https://github.com/Freescale/meta-fsl-arm/tree/daisy/recipes-graphics
fsl-gpu-sdk: https://github.com/Freescale/meta-fsl-demos/tree/master/recipes-graphics/fsl-gpu-sdk
Any comments, suggestions, ideas?
Thanks & Regards,,
Vikash
