Hi there,

I have a 2 lane eDP display panel, which offers Lane0+/-, Lane1+/- and Aux_Ch+/-, there is limited information for this eDP interface and I noticed the iMX8 HDMI interface supports the lane 1, 2 and 4 configuration. But I am uncertain how to connects the data lane and clock signal, is there any information or reference I can follow? Please advise.

Thanks,

Gilbert

Hi Igor,

Thank you for your info!

Refer to the document, MX8M_eDP_APP_NOTE.pdf, I can simply follow it and use only the HDMI_TX_P_LN_3, HDMI_TX_N_LN_3, HDMI_TX_P_LN_2 and HDMI_TX_N_LN_2 due to my eDP display panel has two lanes only, right?

I would like to make sure I got this correctly, please kindly confirm.

Many thanks again!!

Gilbert
