PI has died ?

I was doing a bit of assembler debugging using StrongED and the PI hung on me. Thought it may of been StrongED causing it. So pulled the power and rebooted. Within 2 mins same thing happened except this time PI wont reboot.

Is this a known problem with some Pi’s ? Is there something I should be watching out for when I replace it ?

Is it an sdcard issue ?

Very doubtfull but is it a RISC OS issue somehow ?

PI version is PI 2 model B V1.1
SD card is Sandisk ultra HC 1 class 4 8GB

Also had 128GB USB stick plugged in at time

This sort of freezing is usually related to power supply problems, I have seen it before but have always managed to recover by either changing the power supply or removing things I had plugged into the USB ports.

In one extreme case I actually switched to a Pi Zero because the device I had plugged into the USB port was just too power-hungry for my Pi 3 (which is itself a more power-hungry device than the Pi 2). I didn’t need the Ethernet or other things so the Pi Zero worked well for me in that situation and appears to be stable now.

Try without the USB stick and see what happens. Also check the power supply you are using (and the cable connecting it to the Pi) are of good quality and provide sufficient power.

Might be worth checking that your keyboard/mouse are not particularly power-hungry. I know it sounds strange but some devices are just wasteful of energy and can easily freeze a Pi.

Also as you say, trying a different SD card wouldn’t harm. They are reputed to be unreliable as flash memory often is (although I wonder how much of that reputation is due to Windows being unable to recover them properly?). I have used hundreds of SD cards over the years and have only found one to be unreadable and that was only after I accidentally snapped the end off.

I actually haven’t ever come across a broken Pi, thats with 4 on in the house 24/7 (two now running RISC OS and two running LibreELEC) and loads used in embedded industrial applications I used to make , they seem to be very reliable computers so if you do have a broken one then buying another would almost guarantee you get a working one unless you are incredibly unlucky!

Nice one Glen. Seems like the USB stick was too much for the PI probably due too lack of oomph in the power supply to drive it all. Any recommendations for an ideal power supply with plenty of overhead. 2 amp & 3 amp are figures ive heard mentioned but not knowing my amps from my watts etc it doesnt make a lot of sense to me.

Thanks again Glen :-)

I use an Anker PowerPort5 for when I’m doing development work (it can provide enough oomph on all 5 USB power ports), the Pi Zero system has its own dedicated power source from an old Cisco power supply and adapter board (its a bit Heath Robinson really) and my other media centre Pis are powered via multi-socket adapters that also have two USB ports on the end or 2-gang wall sockets with embedded USB ports.

Its probably overkill but the Anker PowerPort5 is my recommendation because you can power your Pi, charge your phone/tablet/kindle/etc., and probably still have a couple of USB ports left for visitors/friends/family!

I assume this is the product you mean Glen

Anker

Yes I think so.

It was a gift at Christmas so I can’t say for certain it is that exact model but it looks almost identical if not the same!
