问题描述
我在canmv v1.1开发板上的csi2接口接了GC2093摄像头，但是运行sample_uvc_dev_vicap测试，报上述错误，defconfig脚本如下：
CONFIG_MPP_ENABLE_CSI_DEV_0=y
CONFIG_MPP_CSI_DEV0_RESET=0
CONFIG_MPP_CSI_DEV0_I2C_DEV="i2c3"
CONFIG_MPP_CSI_DEV0_MCLK_1=y
CONFIG_MPP_ENABLE_CSI_DEV_1=y
CONFIG_MPP_CSI_DEV1_RESET=23
CONFIG_MPP_CSI_DEV1_I2C_DEV="i2c0"
CONFIG_MPP_ENABLE_CSI_DEV_2=y
CONFIG_MPP_CSI_DEV2_RESET=24
CONFIG_MPP_CSI_DEV2_I2C_DEV="i2c1"
CONFIG_MPP_ENABLE_SENSOR_GC2093=y
CONFIG_MPP_SENSOR_GC2093_ON_CSI0_USE_CHIP_CLK=y
CONFIG_MPP_ENABLE_SENSOR_OV5647=y
CONFIG_MPP_SENSOR_OV5647_ON_CSI0_USE_CHIP_CLK=y
CONFIG_MPP_ENABLE_SENSOR_IMX335=y
CONFIG_MPP_SENSOR_IMX335_ON_CSI0_USE_CHIP_CLK=y
CONFIG_MPP_ENABLE_SENSOR_BF3238=y
CONFIG_MPP_ENABLE_SENSOR_BF3238_ON_CSI0_USE_CHIP_CLK=y
运行log如下：

我试着把CSI0摄像头拆掉，发现启动log中can't probe find sensor on csi0，看起来像是只使能了csi0：
