Got a pi case and out it in, think I might have passed a little hard, don't see any damage but on powering up, only the power light comes in, no network lights in the Ethernet.
Not sure how to troubleshoot this, any hints ?

I agree with Swiss-Toni - even with my brutish hands, I haven't managed to break a Pi through mishandling. If you have a spare SD Card, try a fresh install and see if that works...

Thanks,

Matt

Acutally, found a 64mb sd card, and put the disc image on to it, no difference, unit powers up, but not getting any connection to the network, Ethernet interface not lighting up at all, and tried a known working cable!

looks like its buggered Id say!


Checked the old sd card though, and in my windows machine, it beeps when I insert it, so detects the card, but cant see it as a connected drive/folder

What is the recommended power down/card removal sequence for the rpi runnin alphawerk ?

The card sounds like it is Fked and it also sounds like the familiar problem of power source to the R-PI

What R-PI model do you have
What is the pwr rating on the PSU for the R-PI

By what you are saying it is the PSU that has either lost integrity or is not suffiecient to pwr PSU
Even though you may have been using it over time if it is underated it will cause it to fail....

I thought of power supply, so I swapped with a verified good 2a one and no change. I think I might have something though, the sd card I had was a64gb, which I beleive when you format it, does a format called exfat, which the pi will not boot from. So I need to figure out how to format it as fat, which is actually a bit tricky apparrantly.
Now, the 4gb card I have, I suspect as suggested it is in fact corrupted, as when I insert it into my windows machine, it recognises the fact that a device is present, but there is no drive and no folder structure poppIng up with it.

You have to format it with SDA formater and load command files with etcher laidout as Mattbrain says or it will not work, a 64gb will not format as fat a standard fat32 you can get round this with some softwar but I am not sure how it works with R-PI

Ive managed to format my 64g one now as a 16g fat32, so will give it a go.

OK,

Looks like its sorted, card got corrupted, cant actually recover it either, but the 64gb card worded once I had formatted it as a 16gb fat.

Not sure how/qhy it got corrupted, I did power down the Pi before removing the card (I was putting the rpi into a case).

Any recommended way of doing this ?

The issues with SD card corruption are painful and obviously not desirable for a commercial solution.

I have been making some headway with overcoming this, as it is even more important for the UCM/Pi solution currently in development.

I will be releasing a much improved build in the coming weeks which actually locks the filesystem into read-only mode which should prevent corruption of the file system due to unexpected power failures and PSU issues.

Thanks,

Matt
