[PROBLEM] New RPi Model B shows only 122 MB ram!

[igmi]

Hi Guys,

I have also the newest RPi model B 512.

Revision 000e

it wouldn't start with default xbian install. Only when replacing the start.elf and bootcode.bin it will boot.

i've setup the config txr gpu_mem_512 from 128 to 256 but the free -h still shows 122MB.

it should be showing 256, right?

Can anyone explain this to me?

Thanks in advance!

These are my settings and systeminfo:

Config.txt
initramfs initramfs.gz 0x00a00000
gpu_mem_256=128
gpu_mem_512=256
arm_freq=950
core_freq=450
sdram_freq=450
over_voltage=2
disable_overscan=1
disable_splash=1

Can you reinstall xbian - using the latest image (it has been updated to include the newest RPi) and see if that helps.

If not - use the standard /boot/config.txt and try again. If none of these work, can you post the output from #dmesg via pastebin.com as explained in my signature.

If possible can you post a photo of your model. Tnx

There also seems to be a difference in the start.elf from the one downloaded to the one in the latest xbian Beta 1.1 image. So if it is a kernel issue, this might solve the problem.

is it somehow possible that you used plain "start.elf" and "fixup.dat" instead of "start_x.elf" and "fixup_x.dat" and renaming them to start.elf and fixup.dat respectively?

you didn't post the source of your manually replaced firmware files.

hello,
This afternoon, i tested the total ram with the free commande.
I see also 122 MB of ram !!!!!!!!!!!!!!!!

I have a new raspberry pi with normaly 512 MO of ram and the fimrware patch for the new ram

[IriDium]

@Vorms - can you follow the instructions in Post 2 & 3.

As none of the developers have the new model - it's difficult for them to test, so we need as much information as possible.

It's possible Igmi has fixed it as it's been a while since this problem was first posted.

[mk01]

btw: at last this was a bug in rpi firmware. reported and solved, but don't know which commit exactly.

@Vorms
so you have package xbian-package-firmware 1.4.5 ?

Hello,
thanks for your reply.
I don't undertand exactly.
When I build a SD crd, I install the version 1.0 beta 1.1 that I downloaded fiew weeks before. Because I have new raspberry, I replace 2 files by new one found in the forom.
Is that exact ?
Is the version 1.0 beta 1.1 updated and now compatibe with new raspberry ?
How can I know the xbian-package-firmware version ?
Is the xbian-package-firmware corresponding with the 2 files I have to replace ?
Sorry for the confusing, best regard and thanks for your help

[mk01]

@Vorms,

XBian Beta1.1 should be able to boot from the new RPIs. Updated firmware is part of the img file which is copied to SD card during install.

But with the fix for new model, people started to to report problems with reported (and used) available system memory specially with 512MB Ram RPIs.

Here is firmware from RPI dated Sep. 20th. Can you test it? Do:

Code:

sudo -i
wget http://ivka57.dyndns-ip.com/others/xbian-package-firmware1.4-6.deb
dpkg -i xbian-package-firmware1.4-6.deb

version you have you can check with

Code:

apt-cache policy xbian-package-firmware

or in xbian-config under packages

Hello,

can you please remove "splash" from cmdline.txt and post result?

btw: ad-card resize should not be run twice. card is resized (should be) during _first_ boot, then it should not try again (if partition at max size - resized in step 1))

with the "splash" out of the cmdline.txt, please check whether you get into "Moving root" stage.

[Vorms]

Hello,
I removed the splash and now it's work ! may be a new installer version with new firmware will be welcome...
Many thanks for your help in any case
.
I just see that some HD TV channel work a short time and hang.
In this case the CPU is a 100%, the raspberry is not blocked, i can change the channel.
I have the mpeg licence activeted.
Can I do something ?
Many thanks for your help.

@igmi - Can you confirm this is solved. If so can you change the status from Problem to Solved.
