i2c detect not found

maneesh.singh

Hi,

I am using AIO-3399J EVK and connected some sensors to I2C4.
I am trying to use i2cdetect command it gives an error saying -
i2c detect not found.

I also tried to use sudo also but sudo also not working.
I tried to use su but su also not working.

EVK - AIO-3399J
BSP - Andriod 7.1 from firefly
Command - rk3399_firefly_aio_lvds_box_userdebug

Any suggestion on how I can enable i2c detect in BSP.
