Hi Vinothkumar
from log "hdmi: failed to get edid" seems there is no signal on hdmi i2c :
one can try to check HDMI SCL,SDA signals with oscilloscope and debug it using
hdmi driver sources described in sect.6.4.6.7.3 Source Code Structure i.MX Linux Reference Manual
Best regards
igor
Thank you Igor for the reply.
