嗨喽，我有一个DM368的
开发板，使用的sensor为MT9P031。
我有将内核make menuconfig 里的其他解码器去掉。选中MT9P031
有在sta
tic struct vpfe_subdev_info vpfe_sub_devs[] 添加
.module_name = "mt9p031",
.is_camera = 1,
.grp_id = VPFE_SUBDEV_MT9P031,
.num_inputs = ARRAY_SIZE(mt9p031_inputs),
.inputs = mt9p031_inputs,
.ccdc_if_params = [
.if_type = VPFE_RAW_BAYER,
.hdpol = VPFE_PINPOL_POSITIVE,
.vdpol = VPFE_PINPOL_POSITIVE,
],
.board_info = [
I2C_BOARD_INFO("mt9p031", 0x5d),
/* this is for PCLK rising edge */
.platform_data = (void *)1,
],
],
我的bootargs为
setenv bootargs dm365_imp.oper_mode=0 mem=48M console=ttyS0,115200n8 noinitrd rw ubi.mtd=3 root=ubi0:rootfs rootfstype=ubifs video=davincifb:osd0=720x480x16,4050K davinci_capture.device_type=4;
现在内核启动信息出现问题为：
i2c /dev entries driver
Linux video capture interface: v2.00
ths7303 1-002c: chip found @ 0x58 (DaVinci I2C adapter)
ths7303 1-002c: ths7303 write failed

vpfe_init

vpfe-capture vpfe-capture: v4l2 sub device mt9p031 register fails
No sub devices registered
vpfe-capture: vpfe capture clocks disabled
vpfe_register_ccdc_device: DM365 ISIF
dm365_isif: probe of dm365_isif failed with error -22
请问该如何解决呢？
