该错误大概率是由 I2C 连接引起的。可能是硬件引脚布局存在问题，或者 I2C 数据或时钟的 GPIO 未正确配置。
调试

检查并验证 I2C 数据和时钟配置。
确保硬件引脚连接正确。
提取 CCI 日志来获取更多配置信息。

最近遇到一个比较奇葩的问题：我们kernel层加了后摄的otp后，会出现某些机器概率性前摄ID读错问题，otp读出来的数据也全是0。dtsi文件关于otp的修改···//id读错//otp读错···分析：i2c通信时ok的，但是就是读错了，肯定是读到某个地址的值了，所以id没读对，移除dtsi后摄的otp修改，就能读对。可以确认的是加了后摄的otp导致的。需要注意的是，otp是烧录在sensor。
