I am trying to get some hardware working for a test rig I am building. I needed to monitor some network traffic and take action (activate a bit of safety hardware) when it dropped/rejected a certain amount of data. Thinking it would be easier to use a Raspberry Pi rather than a laptop I sat down on Friday and created a Python (?) script that turned on an LED if it was good and a different one it was a bad packet, while counting the number of bad ones. If the number of bad packets exceeded a limit the hardware would be activated. However the memory card got corrupted. Now it will only boot to Kernel Panic, new memory card, same issue, use Pi straight out of box. Kernel panic, I seem to only be able to get a Kernel panic now. I have tested various points on the Pi for voltages, all seem correct what and if I borrow the card from another Pi it will boot on the Pi that has the Kernel panic. So I wonder if I copy that image from the card to my card will it boot?
8 GB thats what I was thinking, Only one card could be fake, a 16 GB Kingston the rest I bought through Amazon all 16 GB, a mix of Kingston & Sandisk, Also I did buy a Sandisk from PC World. All no Worky! Using a 32 GB Sandisk at work device boots!
Why do you think you won't get fake cards from Amazon?
But with such a bunch of cards it is less likely that all are fakes.
