I have two raspberry pi zeros.I wrote program using nodejs and opencv4nodejs. It works as intended on the first raspberry pi zero. On the second pi zero it crashes frequently due to Segmentation Fault. The weird thing is; If I switch the sd cards, device 1 stills works as intended and device 2 still crashes from Segmentation Fault. This confirms that the software builds are correct and leads me to believe that the second raspberry Pi is different hardware? Shouldn't all raspberry pi zero's be the same? Why would one PI zero get segmentation fault and another works fine? Is there away I can look at specs of the physical hardware to compare is there is a difference?
Also, tried a thrid raspberry pi zero. It errored with Segmentation fault after running for a few mins. I tried with Raspberry Pi B+, no segmentation faults. Again the 1st raspberry pi zero runs without SegFault. It shouldnt be a ram issue right? unless the other Pi Zero ram is messed up.
