   Finally a distribution that doesn’t hog up so much disk space! Unfortunately, networking support does not seem to be working for me. I see that OpenSSH is on the image, but the Pi never responds to ping, never seems to emit a single packet over ethernet, or get an IP address. No idea what’s going on since I don’t have a monitor to use with it.

      That’s odd, on first run it sends a dhcp request and starts sshd for you. You might want to get yourself a USB to TTL Serial Cable. That way you don’t need a monitor. :)

      Which branch did you checkout? if you checked out the marshmallow_h branch, it will not turn on networking (it just runs my game engine demo ATM).

   The Test drive image works like a charm but when I try to build one myself I just can’t seem to get anything going on on the monitor. Am I missing some important package to enable HDMI?

      That’s pretty weird, it should just work. maybe you cloned the marshmallow entertainment system branch on github? That one does indeed lack HDMI console support.

         Yep, you were right. I cloned the wrong branch. My bad, need to read more on how to use git. :x

         Nevertheless, the system is great and exactly what I was searching for, thanks!

   I’m having the same problem as David: eth0 never connects and sshd does not start. I am using the sdcard image downloaded today 9/5/13. Is there a module(s) I need to load? I use UART0 for something else besides a terminal so I disable ttyAMA0.

   Great job. If I can get past this ssh issue I think this will be the ticket!!!!

      I think the image you’re using comes with udhcpc, so you only need to add the appropriate entries for eth0 in /etc/network/interfaces.

      You should add something like this:

      1 2	auto eth0 iface eth0 inet dhcp

   Great work! The new image boots up nicely, but i have one issue with it:

   my usb keyboard is not working

   when i plug it in I see these messages on the console:

   new low-speed USB device number 4 using dwc_otg New USB device found, idVendor=046a, idProduct=0023 New USB device strings: Mfr=0, Product=0, SerialNumber=0

   it doesn’t seem to recognize it as a HID device, let alone a keyboard. it is a fairly standard cherry type G230 USB keyboard. Any idea what could be causing this?

      I have same issue, keyboard doesn’t work. I compiled recent version (revision de019fb4fb08bec4cd5d1ee6d4df221bed7245f4).

         I would suggest trying the same thing as my other comment, if you can send me your dmesg and/or lsusb output, that would be very helpful. :)

      Yeah that’s pretty odd, have you tried using one of the newer kernel config files while building? You can also try using the bcmrpi_defconfig for the kernel (rpi-buildroot currently uses bcmpri_quick_defconfig).

         Ok, I trying to compilie with bcmrpi_defconfig in .config.

         What you mean by “newer kernel config files”?

         Thank you for answer

            In the rpi-buildroot configs directory, you’ll find config files named **raspberrypi-3._defconfig**, they are for the different kernel versions supported by the RPi team.

   rpi-buildroot doesn’t seem to support splash screens. Would it be easy to hack in?

      If you know what you’re doing, yes. ;)

         I found this example (http://free-electrons.com/blog/super-fast-linux-splashscreen/). How soon in inittab could I put that. Before the mount commands?

            Probably not before unless you use something like initramfs. You may want to add it into rc.d instead since you’ll have much better control of when to execute it. :)

   Hmm I’ve tried many option but I fail to have the network started automatically.

   Any idea how I can have it started automatically ? Great job by the way, thanks. Sam

      You should just need to build a dhcp client like dhcpcd or set a static ip on boot.

   Trying and failing to get USB drive support in RPI-Buildroot. Having problems with Museveni and module loading.

      Hmm, you can probably try building in udev support. :)

   Hi and thanks for making it all so easy. I have a problem getting rid of kernel messages on the serial, I have removed all references to ama0 in the cmdline in config.txt, and I have altered inittab to run my application only no tty. But I still get kernel output at 115200 at boot, my app runs at 9600. Do you kow where else the serial is set up to 115200?

   Hola Guillermo.

   Lo primero de todo quiero felicitarte por tu trabajo y por tus aportaciones, ya que son de gran ayuda para nosotros. He probado tu imagen y funciona realmente rápida.

   Ahora tengo un problema pendiente: necesito hacer funcionar la cámara de la RPi, y la verdad no he encontrado demasiada información sobre el tema.

   Por eso quería preguntarte si sabes alguna forma de incluir esta funcionalidad. Por lo que he visto, los ejecutables están en https://github.com/raspberrypi/firmware/tree/master/opt/vc/bin

   ¿Sabes como puedo incluir este módulo en un sistema de ficheros como el tuyo con buildroot?

   Muchas gracias de antemano por la información, un gran saludo. Adrian.

      Hi Adrian,

      You’re in luck, if you build buildroot-rpi from github, it has RPi camera support. Just remember to uncomment the start_x and fixup_x files in the config.txt file.
