Raspberry Pi 2 is unstable.

Former Member
Former Member over 10 years ago

Today has received the Pi2 and was totally disappointed. Is very unstable. I do not even managed to set up the system. After a minute or two system is down. Then apparently fray fs continue after any issues downloading the same message "End Kernel panic - not syncing: VFS Unable to mount root fs on unknown-block(0,0)". That's all.image

    Actually you guys right - this is power supply issue. I tried next steps. Connect Pi2 to Li-Ion battery with USB. See pic. And all working perfect. No one faults over 2 hours. Ok. That is good. I made update and upgrade for apt-get. And further. Get short USB cable with ferrites and connect to another power supply. And whole day Pi2 works very good. No faults and much stable.
    Thanks everyone for advices and help!

    Noooooooooooo!

     

    Don't run those on top of those anti-static bags - while the inside is nice and protective the outside is a farmhouse for static charges.

    Well I would disagree.

    The HDMI lead plugged into the monitor will be providing a ground.

     

    This is the pdf of the bags supplied with the RPi2.

    Please note the inner and outler layers are conductive.

     

    For the reasons of conductivity and possibly thermal, its not the best idea to run them like sitting on the bags.

    For a few dollars you can buy cases ... which aren't listed as conductive or antistatic coated ....image

    Your advice was appropriate for some bags.

    It just happens that these are a very good quality bag  .... better than I thought.

     

    Static builds up and unless it is discharged or dissapated it can cause issues where a pin is raised to a potential higher than the others.

    Discharging one's self by making contact with an earthed surface BEFORE touching the electronics is preferable.
