I run into troubles with a Pi Zero W and Latest Raspbian.
Please note that I'm pretty experienced with the PIs: I Use them since the first version, got several Pi Zero and another Pi Zero W from another retailer (this last one runs fine).
This seems to be an issue with the specific Pi Zero W I just got from Pimoroni:
I use the latest Raspbian Image.
When booting, or apt-get upgrade, or some apt-get install, I get kernel panics and Oops.
(The other Pi Zero W I got runs fine for all this)
This looks like a SD problem, so here is what I tried :
Use other SD cards
I tried with more thant 5 sd cards (class 10, compatible, new ones as well as sd cards that works on other PIs)
Same errors each time. So far, I never get the Pi to apt-get update without crashing.
Tested on too many sd cards and sd cards knows to work on other Zero W, so the issue if definitely not the sd card.
Make sure the power supply is solid.
I used a 2 Amp power supply, a short usb cable. I tried with wlan deactivated. No change.
No doubt about the power supply.
install and run rpi-update
I could install rpi-update and run it.
Rebooted, then same thing, apt-get upgrade or dist-upgrade crashes.
I spent several hours burning sd cards and trying all I thought of.
Wifi only, ethernet adapter only, ethernet over usb only: no change at all, always the crashes.
So it looks like this Raspberry or at least its card reader is defective.
Is there anything else to try ?
