how to connect 8-bit BT656 output camera module with AM3715?

AM3715 device has special IP called "Bridge lane shifter", which allows us to interface your camera output to any bits. Just refer to the TRM section "6.4.5 Camera ISP Bridge-Lane Shifter".

Thanks,

Hello Jerry,

There is already a live example of a OV5640 camera board interfaced with DM3730 EVM which should work for the AM3715 also. Here is the link http://www.e-consystems.com/5MP-HDCameraBoard-omap-am-dm37x.asp.

Hi  Anitha, 

         Thanks for your information, but our OV5640 camera module is diffirent from the above that you introduced,  the camera module data output lane is [9:2],  and  [1:0]   can not be seen.

I want to know how to connect the OV5640  CMA[9:2] with AM3715 camera ISP interface .  we connect the OV5640  CAM[9:2]  with AM3715 CAM[11:4] now , the picture is not display normally , it is very green .  I modify the  value of  ISP_CTRL[7:6]:SHIFT and ISP_CTRL[3:2]: PAR_BRIGE , but can not make it normal.

         It is a urgent issue.

best regards

Jerry Tung

HI, Vaibhav:

       Refer to your introduce ,  it is helpful for me to understand " Camera ISP Bridge_Lane Shifter ",  but I find it is difficult to understand "Sensor : 8 bits  --Connected  to  " in " Table 6-35. Camera ISP Bridge_Lane Shift ",  Is the " Connected to "  concect to  Sensor or  connect to AM3715 camera ISP interface ?

      thanks and best regards

Hi Jerry,

As you said ,the interface is like OV5640[9:2] to AM3715 CAM[11:4], it looks fine and you should be able to get the proper output once you configure the PAR_BRIDGE and SHIFT Registers properly.

If possible post the captured output image.

hi,

    I also want to know  'Is the " Connected to "  concect to  Sensor or  connect to AM3715 camera ISP interface ?'.I guess it means connect to AM3715 camera ISP interface,

I found the SPRUGN4 page 1087,Table 6-4. Camera ISP Video Timing Reference Codes for SAV and EAV.The SAV,EAV code is in the MSB of the 10bits,the sensor should

connect to the same bits . if  the decoder  such as TVP5146 is 10bits mode and the SAV,EAV is in the MSB[9:2],the TVP5146 D[9:0] should connect to ISP [9:0];the decoder TVP5150 is 8bits mode and the SAV,EAV uses[7:0],so the tvp5150 should connect D[7:0] to ISP [9:2]? am I correct ?

Hi,

Can you specify the shift  value,

Hi,

data lane shift

0x0: No shift.
CAMEXT[13:0] - CAM [13:0]
0x1: Shift by 2.
CAMEXT[13:2] - CAM [11:0]
0x2: Shift by 4
CAMEXT[13:4] - CAM [9:0]
0x3: Shift by 6
CAMEXT[13:6] - CAM [7:0]

I didnt understand what does it means?
