[ 8.870000] i2c16_transfer(0x36, 0x30)
ERROR (drv_imgs_OV2715_2MP.c|DRV_imgsCheckId|598): DRV_i2cRead16()

Rules.mk 部分配置如下：

SYSTEM := IPNC

IPNC_PLATFORM := DM368

BOARD_ID := BOARD_AP_IPNC
IMGS_ID := IMGS_OV2715_2MP

采用appro的方案，硬件sensor为OV2175

麻烦大家帮忙分析一下，google有类似的问题，但是和我们的场景不太一样，先谢过了

    用i2crw测试日志如下：

    ./i2crw.out -r 0x6c 0x300A
    [ 381.450000] i2c_transfer(0x36, 0xa)

    I2C: Read ERROR !!!

    你好，

    错误是I2C读失败了。你能否测量一下I2C上信号，检查DM36x输出端是否正常。

    姜还是老的辣，呵呵，拆机后sensor排线重新插了一下，问题解决了

    thx  chris meng ！
