<![CDATA[Segmentation Fault]]>Evening viewers,

I had MM running fine on the 3B+, have got myself a Zero W and assume I have shot myself in the foot…

I took the SD card out of the 3 and put it into the Zero. Initially I had issues getting the keyboard and mouse to work, after much research I added a USB hub with it’s own power supply but this brought with it boot issues. I still am not sure of the why.
Ultimately it booted into Raspbian. I opened a terminal, changed directories to the Magic Mirror but when I typed npm start I got a Segmentation fault.

Am I right in thinking there’s a difference between the code for the Zero vs the 3?

Any and all help gratefully accepted.

Cheers,
Rob

(still in the research stage)
If there is this would make importing Magic mirror setups to another device. Simply install MM on the new device and then restore a backup.

I spent much of yesterday afternoon and evening online, looking for an answer and didn’t come up with anything but a reinstall. I like to know the why for next time and the answer just may help someone else out in the same situation.

I’ll put this card back into the 3B+ and start with a fresh card/install then report back in this thread.

Cheers,
Rob

Thus the SD card or image from the 3B+ will not work in the Zero W
