Hi,
My re-built KK4.4.3 image works fine except LVDS port which replaced panel attached.
I followed described instructions and I tried to change LVDS clock from 38MHz to 30MHz but couldn't change yet.
>LVDS pixel clock on i.MX6
>https://community.freescale.com/message/491746#491746
(1) arch/arm/mach-imx/clk-imx6q.c
clk_set_parent(clk[ldb_di0_sel], clk[pll5_video_div]);
(2) drivers/video/mxc/ldb.c supposed to move arch/arm/boot/dts/imx6qdl-sabresd.dtsi
clock-frequency = <30000000>;
Can anyone help me to correct my LVDS clock setting? Which files do I need to fix?
Thanks.
Solved! Go to Solution.
I found the comment how to change the clock source in 154 line of kernel_imx/arch/arm/mach-imx/clk-imx6q.c.
I added parameter as following then it worked.
u-boot=> setenv mmcargs... ldb_di_clk_sel=pll5_video_div
u-boot=> boot
