What are changes needed to have HDMI working with 1280x800 resolution on imx6
Android version : Android M
Kernel version : 3.14
Right now making modification
compatible = "fsl,imx6dl-SBC_A62", "fsl,imx6dl";
mxcfb1: fb@0 {
compatible = "fsl,mxc_sdc_fb";
disp_dev = "hdmi";
interface_pix_fmt = "RGB24";
mode_str ="1920x1080M@60";
mode_str ="1280x800M@60";
default_bpp = <32>;
int_clk = <0>;
late_init = <0>;
status = "okay";
This is the only change I am making at the moment. Issue is that 3/10 times HDMI screen fails to turn on. Please let me know if I am missing any other changes
Hi Igor ,
Thank you for your reply. I have gone through the thread shared by you .
one of the points mentioned in the discussion was to update the 1280*800 timing parameters into mxc_edid.c and mxc_hdmi.c.
I have made changes in the mxc_edid.c file but i am not quite sure what changes are required in mxc_hdmi.c file
Any hint could help.
Regards ,
Dileep
