When i execute cmd "i2cdetect i2c -y 1" on TDA4 board,i get message like "omap_i2c 40b10000.i2c: controller timed out".

Can I access mcu_i2c_1 from A72 ?

    Hi Nathan,

    I checked the schematics for TDA4VM. SDA/CLK lines cannot be muxed on j7-evm as
    the other mux modes are in use. Basically mcu_i2c1 cannot be used on TDA4VM board.

    However you can use mcu_i2c0. That is working fine on both U-boot & kernel.

    Best Regards,
