OV8858 sensor interface with sochip s3 allwinner in Beginners Posted February 14, 2019 Hi , We are working on sochip s3. We are trying to interface a new sensor( CSI - MIPI ) with S3 chip with interface add a new file for a new sensor. Required changes : Change in .fex file, change twi_id and twi_add. Also, change module name and address at module load time. $ insmod /lib/modules/3.4.39/vfe_v4l2.ko ccm="ov8856" i2c_addr=0x6c But we got below an error : [ 19.888515] [VFE CCI_0 ERR] Status error at addr_8bit = 6c, wr_flag = 1, val = 1000a30 [ 19.888764] [VFE CCI_0 ERR] Status error at addr_8bit = 6c, wr_flag = 1, val = 1000a30 [ 19.889007] [VFE CCI_0 ERR] Status error at addr_8bit = 6c, wr_flag = 1, val = 1000a30 [ 19.889018] [ov8856_mipi_2lane]sensor read retry=2 [ 19.889024] [ov8856_mipi_2lane]error at sensor_detect [ 19.889031] [ov8856_mipi_2lane]chip found is not an target chip.

Hi ,
We are working on sochip s3. We are trying to interface a new sensor( CSI - MIPI ) with S3 chip with interface add a new file for a new sensor.
Required changes :
Change in .fex file, change twi_id and twi_add.
Also, change module name and address at module load time.
$ insmod /lib/modules/3.4.39/vfe_v4l2.ko ccm="ov8856" i2c_addr=0x6c
But we got below an error :
[ 19.888515] [VFE CCI_0 ERR] Status error at addr_8bit = 6c, wr_flag = 1, val = 1000a30
[ 19.888764] [VFE CCI_0 ERR] Status error at addr_8bit = 6c, wr_flag = 1, val = 1000a30
[ 19.889007] [VFE CCI_0 ERR] Status error at addr_8bit = 6c, wr_flag = 1, val = 1000a30
[ 19.889018] [ov8856_mipi_2lane]sensor read retry=2

[ 19.889031] [ov8856_mipi_2lane]chip found is not an target chip.
[ 19.889037] [VFE_ERR]sensor initial error when selecting target device!
So Please help me with this.
Thank You.
