Migrating to 512MB RaspberryPi

Mon Oct 15, 2012 4:09 pm

Currently I own a rev. 2.0 board and I have ordered the upcoming 512MB pi. For the migration process, is it possible to just swap the SD-card reboot and I am good to go? Or does it take more than that?

Yes but you won't get the 512 memory go to the front page and download updated .elf file

Also remember if you've overvolted your current Pi so that you don't void your warranty the first time you boot up your nice, shiny new 512MB Pi... ;-)

That raises an interesting question. If I overclock my pi using the raspi-config utility, then plop my SD card into a different PI, does that trip the warranty bit? Or do the updated elf files go, "These settings are in the list of approved settings, therefore don't set the bit"?

raspi-config will only insert allowed settings, so you won't risk the warranty bit by swapping cards.

Not with the standard raspi-config overclock "Turbo" modes, but if you have added the force_turbo or current_limit_override (with over_voltage > 0) settings on your old 256MB Pi, and having completely forgotten you are using these settings then pop that same card into your new Pi you can kiss your warranty goodbye... :)

Thank you kindly! I thought that was the case, but I always like to make sure I have my facts straight before I shoot my mouth off :lol:

I was wondering if "sudo rpi-update "384/128" would bring in the right elf file?

I am sure it will eventually work that way but rpi-update may have to be changed first.

You have to download the correct .elf, file then change the name to start.elf then place in your /boot partition. You will be replacing the start.elf that is already there.
https://github.com/raspberrypi/firmware ... aster/boot

IOt looks like there are three .elf files available there, oops make that 4!
arm256_start.elf = 256 to ARM and 256 to GPU; Good for XBMC or other media device setups.
arm384_start.elf = 384 to ARM and 128 to GPU; Probably the best split for most users
arm448_start.elf = 448 to ARM and 64 to GPU;
arm496_start.elf = 496 to ARM and 16 to GPU; Servers
512MB version 2.0 as WordPress Server
Motorola Lapdock with Pi2B
Modded Rev 1.0 with pin headers at USB

I doubt this will come up for anybody else but I had an SD card (with Debian image preinstalled) I got with a 256MB Pi and added arm384_start.elf, arm448_start.elf, and arm496_start.elf and tried to use it with the 512MB Pi I got today. All three of them reported 247MB from "free -m". I did an "apt-get upgrade" and all the memory became available to me. There must have been a 256MB limit in the Debian image that was fixed by apt.

Maybe this info help somebody else!

I also had the debian 6 in my starter pack with the new board. As suggested by cmshowers I did a sudo apt-get update, then a sudo apt-get upgrade. It took the best part of an hour to complete. But there are no new elf files in /boot, and the memory allocation remains as it was. After the upgrade sudo raspi-setup no longer works as the command is not found. :o

Which front page? Can't see anything about elf files on the raspberrypi.org main pages.

What do we do with this elf file when we get it?

4th article down on the main page
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.
here is a link to ... https://github.com/raspberrypi/firmware ... aster/boot
I now own 2 RPi - does that mean I own a circumference?

Sorry -- complete beginner with linux -- forgive any ignorance detailed below

Downloaded 'arm384_start.elf' with Midori in the GUI and saved to desktop

Used Su passwd root to enable the file to be copied to the /boot directory

I note that the file has a different icon from the other 'elf' files; in this case, shown as an html doc (as confirmed by looking at properties and seeing that it is set to 'open' with Netsurf web browser; the other existing 'elf' files are not set to open with anything when viewed in properties, i.e. the field is 'blank')

Do I need to worry or would this sort itslef on a reboot (i.e. obviously after renaming the 'arm344_start.elf' to 'start.elf')

I hope all the above makes sense!?

Solved it!

I had the same issue, this worked for me:

Code: Select all

sudo rm –f /etc/udev/rules.d/70-persistent-net.rules
This will remove all network devices, and will be reconfigured on reboot.

For anyone wandering into this thread from Google, the above steps (downloading special start.elf) are no longer needed, as per this commit: https://github.com/raspberrypi/firmware ... 2dc6281176
Just use a recent start.elf and specify the amount of GPU memory you want in /boot/config.txt and the rest should become system RAM.

I just got my 512 MB Pi, and I simply swapped the SD card, and I see the amount of system RAM that should be there (I use 16 MB for GPU):

Code: Select all
