Yes, that is a Model B - the 2708 is an internal Broadcom part number for the Silicon itself, but the SOC you have will be the BRCM2835 package.

sorry to hijack, but: how come that with the exact same cpuinfo, and after all updates etc and with
gpu_mem=64 in the config, I get this for free -m ?

Are you using rasbian ?

You should have

Code: Select all

$ uname -a
Linux raspberrypi 3.2.27+ #250 PREEMPT Thu Oct 18 19:03:02 BST 2012 armv6l GNU/Linux

$ sudo /opt/vc/bin/vcgencmd version
Oct 25 2012 16:37:21 
Copyright (c) 2012 Broadcom
version 346337 (release)
It really should work if you are on those versions.

Code: Select all

$ free -m
             total       used       free     shared    buffers     cached
Mem:           438         45        392          0          8         22

What do you have in /boot ?
I missed once fixup.dat and fixup_cd.dat and that caused similar memory problem for me.

Yes, basically looks good, but there are strange small differences in fixup and start file sizes.
My listing:

Code: Select all

$ ls -l /boot
total 16872
-rwxr-xr-x 1 root root   17764 Oct 28 19:40 bootcode.bin
-rwxr-xr-x 1 root root     142 Oct 29 00:11 cmdline.txt
-rwxr-xr-x 1 root root    1180 Oct 29 00:11 config.txt
-rwxr-xr-x 1 root root    2020 Oct 28 19:40 fixup_cd.dat
-rwxr-xr-x 1 root root    5282 Oct 28 19:40 fixup.dat
-rwxr-xr-x 1 root root     137 Oct 29 01:01 issue.txt
-rwxr-xr-x 1 root root 2104952 Oct 28 19:40 kernel_cutdown.img
-rwxr-xr-x 1 root root 9522048 Oct 28 19:40 kernel_emergency.img
-rwxr-xr-x 1 root root 2695192 Oct 28 19:40 kernel.img
-rwxr-xr-x 1 root root  523144 Oct 28 19:40 start_cd.elf
-rwxr-xr-x 1 root root 2347828 Oct 28 19:40 start.elf
If you really have the latest firmware and kernel, I would try downloading the bootloader files and copy those over the current ones (after taking a backup of the SD card):

Code: Select all

$ cd test-directory
$ sudo apt-get download raspberrypi-bootloader
$ sudo dpkg --extract raspberrypi-bootloader_1.20121025-1_armhf.deb testboot
After I would copy those files that are different into the boot folder.

thanks, but following this thread http://www.raspberrypi.org/phpBB3/viewt ... 26&t=22199 it seems that I simply have the 256mb version so it's gonna be pretty hard to squeeze 5120mb out of that :D
