Part Number:AM5728

Tool/software: Linux

Hi

    I wanna enable i2c2,and connect a sensor with I2C interface;but when linux booted up, I executed the command "i2cdetect -r -y 1" and kernel told me that omap_i2c 48072000.i2c:controller timed out.It make me confused,any available suggestions would be appreciated.

    SDK:am57xx-evm-linux-sdk-src-05.02.00.10

    Kernel:linux-4.14.79

    Note:

1. I enabled the I2C2 in uboot/linux ;

2.My HW design included pull-up resister in right place and the bus is at expected voltage.(3.3V)
