The 'solved' is because the solution was to buy a new Pi. - thereby suggesting that the issue is with the Pi rather than the SD card or anything else suggested in this and other threads.
If this new one breaks in the same way, then we'll at least be able to isolate that it's got a higher probability that it was something to do with what I'm doing with it. If however this one doesn't
break in the same way, then what should we assume from this? It's possible to infer that some accidental or unconscious action on my part caused the failure of the previous one - so we're still no further forward in that case since unless I monitor under lab conditions my every action with the new one in the hopes that I'll accidentally cause the same issue. It's impossible to even speculate what that might be since I've not yet come across anyone who has actually been able to offer an explanation as to what the green light problem is other than "The Pi isn't reading the SD card" - but since that's not great as a solution (how do I prevent the Pi not being able to read the SD card?) then we're still no further forward are we?
The problem was that the Pi wasn't reading the SD card. I plugged the old
SD card into a new
Pi and it booted instantly. Therefore the problem is with the Pi, therefore the solution
is to replace the Pi. Does that make sense to you?
What you're asking is what caused
the problem in the first place, and to that, I don't know - and from what I can tell, no-one knows yet.
I did nothing bad to the old one (and compared to many I've seen on YouTube videos being haphazardly strewn across workbenches and even (re)soldered and components removed/altered, then mine was treated very well!), unless you can see something in my original post that leads you to believe I did something bad? If you can I'd love to know since I obviously don't want to do it again and the information may well help other people having the same issue
Since the Pi is supposed to be a kids learning device, then I can only assume it will have been tested to withstand a degree of mistreatment - I'm sure that anything my Pi endured would not have been even close to as bad any the 'average' Pi experience - and if I was able to 'destroy' as you put it, my Pi after plugging in componenets intended for use with the Pi, then that still suggests there is a problem with the Pi doesn't it?
As far as I can tell my previous one worked fine one day, then next time I switched it on (after making no changes or touching it at all) it had the green light issue.If it had happed while I was playing with the GPIO pins or something then I could at least speculate that that was the cause, but as I said, I'd not touched the Pi at all other than to plug stuff in (carefully I might add) and it did work fine until suddenly it didn't.
I've also read nothing to suggest that anyone else having this same issue (of which there seems a few) has 'destroyed' their Pi with some action either, there seems no common ground, and I've read no definitve answer on 'what caused it'.
Most people who reply tho topics with this issue (the solid green light) offer a range of 'user error' fixes, like properly formatting the SD card, etc. read up to see the usual suspects. And also often suggest it may be issues with peripherals or somethig like that. All these are great possible solutions to common issues, however they are totally useless here since none of them actually work - and I've read nothing on any post anywhere about anything 'fixing' the solid green light issue (though I admit I've probably not read everything!).
I also have done things like checked voltage across the board and followed many other guides and tutorials I found all over the place on diagnosing issues with the Pi - nothing at all provided any useful resolution other than "it wasn't that".
You can see that I have proved that at least in my case, the issue isn't with the SD card, formatting of the SD card, the distro used, the power used, the TFT screen used, the keyboard or the way that I assembled any of those things togehter - since I literally plugged the new PI into the old configuration and it works perfectly.
The solution to the 'green light' issue is to buy a new Pi apparently
, unless you have another solution?
