Hi freescale,
My self i am VIjay. I am developing a custom board with reference of sabresd but i am facing below problems.
1. EDID for HDMI is not working properly even i config with i2c properly.It showing below message.
mxc_hdmi mxc_hdmi: No modes read from edid
mxc_hdmi mxc_hdmi: create default modelist
mxc_hdmi mxc_hdmi: Read EDID again
mxc_hdmi mxc_hdmi: No modes read from edid
mxc_hdmi mxc_hdmi: create default modelist
2. Actually i want to connect with the board 1280x768 @ 65Hz but it always config to 640x480@60Hz
& I seen the EDID supportable parameters under /driver/video/mxc/mxc_edid.c(also configured to 1280x720 @ 60Hz ) like below. but display not working.
