yesterday my new raspberry arrived. After the first contact with an 256MB board (a month ago) i'm a bit familiar with those boards.
The challenge was: how to enable the 512MB RAM functionality.
If i use the default raspian image, only 256MB RAM are visible.
If you read this official post: http://www.raspberrypi.org/archives/2180
...It looks like, you only have to download one file, and 512MB are available.
But the file, where the post points to, does not exists.download arm384_start.elf
So i downloaded the start.elf file, reboot - and still 256MB available.
Searching the web i found information, that somebody from the community wrote a tool to upgrade the firmware.
At this point of time my question was: what means "firmware" in the raspberry world. Normally a firmware is a software, which will be deployed (burned) on the chip. (like firmware for PC mainboards)
But (i'm not sure) in the raspberry world "firmware" is one (ore more) binary, which is loaded on every startup during boot(?).
After downloading an running rpi-update (where i get an bad feeling by running "some" tool from "anybody" downloaded "somewhere" from the web, which makes "something" with my machine)..
...the system still runs with 256MB, because you have to add an parameter to the config.txt (where you have to search the web again, how is the syntax of this option)
To make a long story short - there are a lot of questions and hurdles to activate the 512MB RAM:
1.) is there anything to do to enable the 512MB RAM?
2.) if yes, what is to do ?
3.) what tools i have use? Which one is/are trustworthy?
4.) are there any configuration-steps after upgrading, installing, etc.
I'm working on a dozen of linux system every day, but those steps are raspberry specific. So i needed one and a half hour only to activate the 512MB. Including reading threads at this board (which isn't funny, since some threads have 10 pages and more!)
Probably a lot of user has the same issue like me.
So my question is: could it be possible to place an "how to enable 512MB RAM after unboxing" - HowTo on an prominent place?
