Hi, I have forwarded your question to an expert for comment. Regards, Yordan

Hi user3829173, Could you please show me the TDA2EVM5777 schematic that you exploring? According to Vision Application Board Schematic Rev D.pdf - link - www.ti.com/.../sprr225 (TDA2EVM5777), the HDMI SCL/SDA pins of RU108 must be connected to F17 (i2c2_scl) and C25 (i2c2_sda). Regards, Lyuben.

Hi Lyuben The schematics file name is "516582H_VAYU_EVM_13NOV2015_H",but I don't know how to provide you the link. What I confused is not I2C scl & sda,but the select pin of RU108 Pin1 of RU108 is connected to ball E15 of TDA2 but there is no GPIO function in ball E15 , why can E15 control the select pin of RU108? Thank you~
