I have an image which I use on a 3B for code testing, and another one used for production versions. I have updated the firmware per RPi.org instructions on both.
When I insert the card into a 3B+, one of them boots fine, and the other one does not - it gives me 4 long flashes, and 6 short ones.
I tried three 3B+ units, all behave the same.
Anybody have any ideas? Any hints would be most welcome.
