Cluster ivport-v2, x8 camera(V2) does not working

x8 cameras, x2 ivport-v2 ivport-v2(first layer) : 'A' jumper bridged / 'X','Y' jumper no bridged. ivport-v2(second layer) : 'B' jumper bridged / 'X' jumper bridged.

But, ivport-v2(first layer) works without ivport-v2(second layer)

help me

were you ever able to find a solution to this problem?

Hello

Did you find a solution for stacking two boards?

I define the two boards as iv=ivport.IVPort(ivport.TYPE_QUAD2, iv_jumper='A') iv2=ivport.IVPort(ivport.TYPE_QUAD2, iv_jumper='B')

Then I try

iv.camera_open() iv.camera_change(1) iv.camera_capture() iv.camera_change(3) ## (because I have hooked the second board to the port of the camera 3 on board 1) iv.close() ## if i dont close this one before opening the other one it bugs out .. ? iv2.camera_open() iv2.camera_capture() ## and it takes a picture with the camera from the first board! Presumably having to close the first board is not ideal but otherwise I dont know how to open the second one..

I also tried just doing iv.camera_capture with the port of the third camera of the first board, where the second board is hooked, without calling the second board. An image does come up, a part of which is the picture I want but it is really messed up..

Any help or advice?!

Hi, ArvindNand, SandBC

I couldn't find a solution with ivport...

So I made my own PCB borad with FSA642 MIPI multiplexer and succeeded.

ok thanks! the more i try the more I think you cant really stack two of these boards.. Did you ever try with the Arducam mutliplexer?

Any chance you re commercializing your board ? :)

Craig-Lee commented 6 years ago

I tried to Arducam, But didn't work. So, I asked the company(Arducam) a question. But they said only four cameras are possible.

If you want, I can send you the specifications of our product.

Hi Craig Lee

That would be interesting yes. I created my own PCB but it does not seem to recognize the camera.. I am only using mux analog multiplexer maybe I should only use that to bus the i2c? Maybe your multiplexers are better at handling CSI. Did you have to alter any code to initialize the cameras? Let me know if you can send more info, thanks!

Thank you
