11:24 <jnettlet> Nilesh_, did you point a framebuffer at it?

11:24 <Nilesh_> jnettlet,no ...how to do that ?

11:26 <Nilesh_> the steps i'm following here http://pastebin.com/bDvMiehZ is rite??pl help

11:26 <jnettlet> Nilesh_, look back that the sabresd dts files and you will see an entry for mxcfb1

11:26 <jnettlet> there you see it is designated disp_dev = "ldb" that is used to connect it to the entry you have created.

11:27 <jnettlet> then up at the top you will want to make an alias for your new mxfb device because linux starts enumeration at 0 not 1

11:30 <Nilesh_> jnettlet: i derived ldb from and copied it in imx6dl-wandboard.dts  https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/tree/arch/arm/boot/dts/imx6qdl-sabresd.dtsi?id=refs/tags/v3.14.1

11:42 <Nilesh_> jnettlet: there is no disp_dev [&mxcfb1 {status = "okay";}; ]

11:46 <jnettlet> Nilesh_, that is because that is the linux-stable tree, and the dts entries there use the imx-drm driver, not the fbdev driver used in the fsl 3.10.17 kernels

11:46 <jnettlet> you need to look at dts entries from the FSL kernel

11:49 <Nilesh_> jnettlet: u mean to say from the source dir?

11:50 <jnettlet> Nilesh_, http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/arch/arm/boot/dts/imx6qdl-sabresd.dtsi?h=imx_3.10.17_1.0.1_ga

11:54 <Nilesh_> jnettlet:o thanks for that link....so i should alter the imx6dl-wandboard.dts based on your link and follow the same steps as http://pastebin.com/bDvMiehZ...am i rite??

11:54 <jnettlet> Nilesh_, yes

11:55 <jnettlet> If you already have an image built, you only need to copy over the new .dtb file to test

11:55 <Nilesh_> jnettlet:do i need to disable hdmi in kernel menuconfig for lvds to work properly?

11:56 <jnettlet> Nilesh_, no, they can both work simultaneously

11:56 <jnettlet> if you want to test that you can disable it in the device-tree or via the kernel commandline

11:56 <Nilesh_> jnettlet: how?

11:58 <Nilesh_> i'ne just posted uboot env can you have a look whats exactly going wrong?http://pastebin.com/c8mcFn6H

11:58 <Nilesh_> jnettlet:

12:02 <jnettlet> Nilesh_, well in your device-tree you are specifying ldb and on the kernel commandline you are setting up the lcd output device

12:04 <Nilesh_> jnettlet:o i see...how can this be corrected? do i need to pass u-boot args in addition?

12:21 <Nilesh_> jnettlet, do i need to pass any args in u-boot?pl

13:25 <Nilesh_> jnettlet: there??
