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

[   19.889031] [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.
