We compare log between recovery and normal mode when HDMI cable insert.
In recovery mode.there are lose "omapdss HDMI: Enter omapdss_hdmi_display_set_mode".
this function seems trigger by high level function.
Can you help to check HDMI can or can not work in recovery mode in 4AI.1.3.
Or which version software can support hdmi output in recovery mode.
thanks
