Raspberry B or not Raspberry B?

[Ssurfer]

Hello
I try start my new raspberry pi with SD image of some project but don't work. Orginal ( from RS) SD with rasbian work ok. I start thinking maybe problem with SD ok I put image on RS SD but same situation. Start thinking maybe problem with image download image again no success. I take my pi to my colleague who got as well pi we start testing SD card on his pi every single work great. He even download again same image on his SD card his unit working, my not even start just only red power led show up. I send this back like faulty unit to RS and got back 2 weeks later still same situation. Today im just feed up with this small unit witch should be cool project. Is any explanation why this 2 pi so diferent even if they work with same power suplay (orginal from RS) same monitor conector same keyboard mouse. Why 1 of them read and work with any SD without problem another is so stubborn.

PS sorry for my language im not native British.

Is your original RPi, and the project SD card image associated with it, a year or so old?

The RPi hardware specifications have not been static - recent RPi hardware (from mid-2013 onwards - I don't have precise dates) uses different memory modules which need updated 'firmware' to enable them to boot. This firmware is included in recent releases of Raspbian, but I wonder if it might not be on your 'project' SD card?

(I think that matches your description of the situation - I apologise if I have misunderstood.)

Hi,

unplug everything , even SD card, be sure SD card isnt read only, plug SD card and power micro USB only, wait couple of minute and observe PWR and ACT led .

From your picture i saw you use HDMI to VGA adapter which may draw power from RPi, same is with USB conection cable (spouse that is Keyboard) .

Its not hdmi to vga only hdmi to dvi adapter so not using any extra power.
USB conection going to USB powered hub pic of hub https://drive.google.com/file/d/0B3lGao ... sp=sharing

(Belkin 2 in 1 with own power supply 5V and 3,5-3,8 A) .
Plus my pi is using orginal from RS 5V and 2 A pic of pi power supply

So in total i have got over 5A to supply my pi.
And like i told here earlier if i put normal SD with rasbian OS this start in sec without any issue.

I'm afraid you are right. I try to build http://www.instructables.com/id/Ultimat ... me-Server/
and I bought my Pi somewhere around end of November even now I got back from service around week ago so must be with new memory modules (my modules got big letter M on it plus some first line 3RA78 and in sec line D9QHN). I belive this image was made on end of 2012 or begin 2013.
I was looking for so many projects. Now I just stack.

You can manually update your card by replacing
bootcode.bin and start.elf on the 50-60 MB partition which is
visible to Windows with the new files from
https://github.com/raspberrypi/firmware ... aster/boot


This is backwards compatible , you should be able to boot
old and new Pis with the same card after this change.

Thank You Ghans I will try this way.
But noob question how can I dowload this files from this Github?

Click on the filename , a page with a link named "View Raw"
should open. Right click that link and choose "Save Link as" .
Navigate to your already inserted SD Card. Now you can rename
the existing file with the same name , or click save and then
confirm to overwrite the existing one.

You have to do that for both files.

I just ordered a raspberry pi that came packaged with a Micron SoC (part# 3UA78 D9QHN). I am trying to find documentation similar to that Broadcom has put out in their Peripherals Data Sheet (http://www.raspberrypi.org/wp-content/u ... herals.pdf).

I am not sure that the memory layout in micron is the same as broad comm regarding say the base address of the GPIO (I am certain it is not).

Does anyone have any input as far as to where I can find this documentation?

[ghans]

The Micron SoC you talk about is actually just another brand of
RAM on top of the BCM2835. Google "Package-on-Package".
You're not the first one to get confused by the label

Is the OP perhaps getting confused by the Model B rev1 and rev2 changes? In particular the 2nd I2C bus?

No, the OP's new hardware wasn't working with his old firmware and his problem has been resolved by following ghans' advice and replacing his bootcode.bin and start.elf files with the latest version.

Ooops - lost track of who the OP was.
