Re: Raspberry pi crashes within 5 minutes of startup

Besides the power adapter, what else is connected to the Pi?
What sd card are you using?

Indeed he did. That's why I think he is facing up to more than one issue. lsusb isn't showing his ethernet adapter anymore after he connected his keyboard. The loggings however indicate that at some moment it existed.... It wouldn't explain why it doesn't receive a dhcp from his network, but it woul...

Re: Ethernet connection issue

@Cambrian It looks like your Pi is able to send ethernet packets, but unable to receive them. This could be a hardware related issue like a bad sodering on the ethernet connector socket. It's also possible you have a bad ethernet cable, or that some of the cable connector pins don't make proper cont...

Re: Broadband needed for my TV.

It works on a windows bridge setup. I have never tried it with a linux bridge setup. The dhcp request is routed from one interface to the other and should reach your dhcp server (usually your router) like that.

Re: No Internet Connection - Raspian

In the latest proposed debian image, dhcp is enabled for eth0 by default. The first thing that can cause problems is the power supply you are using. It should give the Pi a voltage between 4.85V and 5.25V. It can be measured between TP1 and TP2 on the board. The small adapters that are only 700mA ca...

Re: Broadband needed for my TV.

Maybe you can use some routing scripts and make the Pi work as a NAT translating router. I did this once a long time ago with a pc and red hat linux to create loggings of internet traffic. I can't remember the details anymore. Another option is buying a cheap dd-wrt or Tomato compatible router and u...

Re: Raspbian binaries now available (MESS, MAME, neogeo)

Thanks for the binaries. I would appreciate it if you could provide a link to the sources as well. A short description of what needs to be done to get things compiled would be interesting as well. As the major goal of the Pi is education, and as a lot of linux noobs (like myself) start using it, kno...

Re: USB - the Elephant in our Room

That's interesting information Iostintime. It's a bit like the system freezing when an old ftdi usb2serial is accessed. As long as you don't use it, everything works fine. If you query it's settings, the system hangs. So considering the supply, we could say that the Polyfuses are not an issue as lon...

Re: USB - the Elephant in our Room

I measured the voltage of my adapter arriving at the pi. It's still 5.1V between TP 1 and 2. Besides that, I power my usb devices with a powered hub. So, why does the Farnell recommended wifi adapter stops working, while the Alpha extended range one works fine, altough it's consuming more power due ...

Re: Ethernet connection issue

If lsusb shows the ethernet device on the usb bus, you would expect that side of the chip to work correctly. This leaves the ethernet site. It's possible you just received a defective pi. Maybe one other test you could try is to connect the pi to a 10/100M port. You could do this by placing a cheap ...

It looks like most grief is caused because people don't know that dev's are working on the problem. I am guilty as well, as I haven't checked the raspberry irc channel yet to see if the dev's hang out there.

Re: Ethernet connection issue

Have you tried to boot the Pi without connected usb devices? Remove the keyboard, mouse and boot the pi. If the ethernet connection works, it should show the ip it got just before the login request. You can also check your router webpage to see if the Pi got a dhcp from it's dhcp server. You can mak...

Re: USB - the Elephant in our Room

Not using an usb hub is not really a solution. It's a temporary workaround that might perhaps help in the understanding of the problem. When X is running, the ethernet is dying... Perhaps this is not related to the fact it's X, but just related to the fact that the cpu load reaches 100% when buildin...

In order to make the statistics more accurate, I would like to report problems with the pi usb as well.
