We encountered some problem of Camera integration. Currently our R&D progress is blocked at I2C being not able to driven up。 Even we are using official open-source code project and Devicetree file：
The phenomenon is any enabled I2C bus, SDA SCLkeep low. If externally connect to pull-up circuit，SDA become high voltage，but SCL is still less than 0.2V.
Check dmesg, it reports: “rk3x-i2c ff120000.i2c: timeout, ipd: 0x00, state:1”
Does anyone know the reaosn? |
