Re: Pi4 Not booting, SDcard/HDD works fine on Pi2

Having got my Pi 4 to run - not all USB-C power supplies are compatible with the Pi 4 it seems - by getting an official PSU, my Pi 4 also refused to boot to desktop with occasional flashes off the boot screen etc. I just did an 'rpi-update' to the latest (July 4th) kernel etc and it is now working ...

Re: Pi4 Not booting, SDcard/HDD works fine on Pi2

Think i've sorted it out.

My Pi sits on top of a Network switch without a case and when i've moved it so the PCB isn't touching the switch, its booting again. Weird, perhaps i was causing it to short circuit. Looks like i'll need to make a makeshift case of some sort.

Re: Pi4 Not booting, SDcard/HDD works fine on Pi2

Drilled it down to something weird i've never had to deal with before - It won't boot without an HDMI, got the usual recommendations of hdmi_hotplug_enabled set to 1 Did you get it working by adding this line to the config txt file? Nope, back to stage 1 again, thought it might have been that causi...

Pi4 Not booting, SDcard/HDD works fine on Pi2

Hi all, Having some issues with my Pi4, I'm running it headless right now, but it's getting the link up for the ethernet, starting up the external drive and then nothing... I can't ping or SSH into the device and my router doesn't have a ARP entry for it..The SoC is hot to the touch, so it's not in ...

Re: RPi2 --> RPi4

If you're running okay with Buster, you should be able to just swap everything over the the Pi4B. Depending on how your external HDD is connected (and what it's native interface is), you may want to get a USB 3 cable for it. It should work without that, but with it, you'll get much faster transfers...

RPi2 --> RPi4

My apologies if this has been posted elsewhere already, but I couldn't seem to find the answer i'm looking for. Ordered my RPI4 4GB model last night. I'm currently wondering if it'll just be a simple plug and play job in terms of my SDcard and external hard drive or will I have to reinstall my whole...

An oops in the ext4 driver tends to point to a broken filesystem.

Do this:
sudo touch /forcefsck
sudo reboot


If you see the failure again after that replace your dying SDCard.
Will do this and report back if I get any more errors, Was considering the SD Card might be on it's way out.

Re: Raspberry pi 3 just stops responing.

Do you have another Linux computer you could plug the ssd into?

Do you have the ability to connect it to a monitor? Do you get the splash colour screen when starting it up?

Re: Raspberry pi Kernel error

You're not using "stock Raspbian" you've run sudo rpi-update at least once. Don't do that unless you really understand what rpi-update gives you and how it can create unexpected kernel errors. Revert with sudo apt update; sudo apt install --reinstall raspberrypi-bootloader raspberrypi-kernel to get...

Raspberry pi Kernel error

Keep getting these types of crashes in my kern.log, using stock raspbian. Do I have a possible hardware fault?
