#1

Hi,

I am interfacing I2C1 to ov5640 but below error comes

4.897251] msm_cci_init:1016: hw_version = 0x10000008
[ 4.900981] ov5640_front 1-0078: ov5640_set_power_on: Enter

[ 4.968746] ov5640_front: probe of 1-0078 failed with error -22

How to resolve this issue ? I was checked my dts entry is correct.

Thanks

either the slave address is wrong or it is connected to different i2c or ov5640 is not powered up fully.
