Hi,

We are required to set a HDMI resolution of 854x480 statically. Could not find such support in mxc_edid.c (not able to find in the supported video modes in i.MX6RM, hence tried to edit 720x480 with my custom settings for 854x480). With that am able to see linux logo coming (not accurate maybe 60%) post that image becomes irrelevant. I tried to add that resolution in display_mode_fb0.conf (U:854x480p-60) but it didnt help

Please suggest

Thanks, AMR

I had tuned the pixel clock such that am able to see the penquin logo coming clearly now. But once Android boots up display becomes lost. Tried adding that resolution in display_mode_fb configuration file in Android, but doesnt help at all.

Could you please help us on this Android part of configuration

Also have seen a BUG_ON in "kernel_imx/drivers/video/mxc/mxc_edid.c" mxc_edid_read function, Is it resolved in the latest kernel. we are using 3.10.53 kernel
