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:Â 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 😀
