Enable 512MB RAM on latest Raspberry Pi

At first I was very disappointed, because my new Raspis showed only 256MB RAM, although the shop promised to deliver the new model with 512MB RAM.

Mr. Watterott answered my email- support request within 5 minutes (!). He told me, that it’s a software issue and pointed me to this link, showing how to identify, if the SoC has 512MB of memory: www.raspberrypi.org/archives/2191

Luckily my boards have a chip with “4G” in the model number 🙂

Shortly after that, I found out, that a new firmware already exists:  www.raspberrypi.org/archives/2180

Update: Those of you lucky enough to receive a 512MB Pi this morning can download updated firmware here. For example, download arm384_start.elf and rename it to start.elf on /boot partition. You will then have a 384M/128M memory split.

Replacing the /boot/start.elf on the SD-card did the trick 😀

Today I received 2 Raspberry Pi boards from watterott.com – Thanx for the fast delivery!

Specs: www.watterott.com/de/Raspberry-Pi-Model-B

During installation and configuration some bugs appeared, so here are some notes to get around:

I used this debian wheezy image: www.raspberrypi.org/downloads

and followed the linux console install guide elinux.org/RPi_Easy_SD_Card_Setup

At first various problems occurred: locale- and keyboard- config did not work in raspi-config, apt-get dist-upgrade failed to install libgcc1, …

so I changed the dd command to blocksize 1MB and re-installed the SD-card:

dd bs=1M if=~/2012-09-18-wheezy-raspbian.img of=/dev/sdX

Those problems did not disappeared, instead:

  • HDMI to DVI-D(igital) adapter works instantly
  • USB-keyboard and mouse work instantly
  • 1000mAH 5V adapter is strong enough to power the board with keyboard LAN and DVI connected
  • apt-get dist-upgrade works
  • locale- and keyboard- config works in raspi-config
  • LXDE desktop works
  • network and ssh-daemon up and running

Installation of some basic tools:

apt-get install mc screen rcconf tmux

Moving on to some multimedia stuff, I found alsa and sound- modules correctly installed, so I added:

apt-get install mplayer vlc

work in progress…
