Re: How to debug faulty connection to camera board?

Well in the end with the help of a logic analyser and a voltmeter, and 6by9 and others, I just discovered that somehow CAM0 data lanes were "corrupt" and by using CAM1 data lanes (and changing the Device tree blob accordingly), I can have it work again. It still baffles me why CAM0 lanes w...

Re: Typical timing of camera signals: confirmation?

Ok. Using 2 Data lanes and clock on CAM1 bus seems to work. Cannot fathom why CAM0 bus stopped working though. I just changed one line in the Device Tree file, saying: pin_define@CAMERA_0_UNICAM_PORT { type = "internal"; number = <1>; }; before it was number = <0>; and of course rewiring t...

Re: Typical timing of camera signals: confirmation?

Update: I disconnected from power the CM + Breakout board, and connected single pins (GND and 3V3) from another, powered, Raspberry to the breakout board, one single pin at a time. Then using a Voltmeter I checked that the voltage was as expected at camera board connector (the Hirose FPC connector p...

Re: Typical timing of camera signals: confirmation?

Thanks 6by9, So basically the problem could be in the 3 differential pairs signals? That the signal received is not correct or corrupt? I will double and triple check all the connections, even though I am pretty sure they are OK. But anyway, something MUST be broken since it worked and, after rewiri...

Re: How to debug faulty connection to camera board?

Ok, so the Gumstix is just a generic expansion testing board. What I am doing different from you is wiring the GPIO/CAM pins to a second breakout board and thence to a Molex 15 connector, so it should not ben that different. I know about the differential pairs.. but it seems to me that since they wo...

Re: How to debug faulty connection to camera board?

hi aBUGSworstnightmare, so if I understand you correctly, you also prefer something different for CSI connections? Did you design the PCBs yourself or are they available to buy someplace? In what do they differ from the Gumstix ones? But this does not solve my conundrum.. why i nthe world did I unwi...

Hi again aBUGSworstnightmare! as for the Gumstix board, I still prefer it to the official one because I plan to (and have already started) design a carrier board with custom ports, and so I need a complete breakout of the CM pins to do some prototyping. Among other things I don't need the standard c...

Thanks 6by9, I had found them already on AliExpress. Try to understand me, it's a big leap going from Mouser or DigiKey to AliExpress :D It's terrible not having a decent datasheet. but the M12 mounting seems a little bit bigger than the stock one on the camera module, or am I wrong? But it's a nice...

Yes, I suspected it.. but my reasoning is that for a prototype or limited run on IndieGogo (if I will be able to) this should / could be enough and then I will have time to find another sensor I haven't found a package that suits my need. Either I can find on AliExpress sensors+case with a long cabl...
