Analog Device BLIP2 Board Questions.

created by Gseq in Boston Engineering Collaboration Group - View the full discussion

Hello,

We are working on a proposal which involves mating a camera sensor to a custom board. We were hoping to use the BLIP2 platform to prototype this.

Could you get us in touch with the developer who created the kit and answer the below queries

Questions:

1. Our requirement is to interface 12 to 18Megapixel cameras. The highest VGA camera that the BLIP2 can handle is a 2MP(640x480) camera from Aptina or Omnivision.

Can a higher resolution camera be interfaced with the BLIP2. If yes, what changes does it involve. 

One way is to re-spin BLIP2 to replace the VGA camera by a higher resolution camera, assuming the latter supports parallel output (such as DVP). If the camera only supports differential output (e.g. MIPI), a bridge device is needed to convert the differential to parallel. Lattice FPGA is one choice for the bridge. Alternatively, if the camera supports USB output, it can be connected to the USB port of BLIP2. In this case, BLIP2 must be configured as the host.

2. The cameras that come with the kit have an ePPI interface. Does the kit support MiPi? 

eg: Jetson TK1 camera board | NVIDIA camera | TK1 camera module 

Can ADI support us in this endeavor.

No, BLIP2 does not support MIPI. MIPI is on the roadmap but is currently not supported. A bridge device (like a Lattice FGPA) would be required to convert MIPI to ePPI.

3. How does the software licensing work in this case? Would we have full access to the kernel and source code?

Binary code is offered free of charge (available for download from www.analog.com/blip). Source code would be under separate contract. Please contact ADI sales team.

4. The current kit example streams video data and analyzes it. We plan to capture images @1Hz and store them into the SD card. Is this possible.

BLIP2 has a connector for SD card.

5. Can the captured data be copied from the SD card into a host PC... or describing it another way, does the USB support Mass Storage Class(MSC).

The USB currently only supports Bulk transfer. It does not support MSC. It should be possible to modify the BLIP firmware to copy SD card to PC via the USB Bulk link.

I can hop on a call with the team here if needed.
