I came across this discussion on Raspberry forum...

Code:


mattd on October 2, 2011 at 4:37 pm said:
1) With no onboard data storage, how does the GPU go about starting the
 boot process? Is there something hardcoded that allows it to mount and
 read the SD card?
2) Was booting RasPi without NAND/NOR uniquely difficult, or is this common with ARM chips?
3) Any interfaces supported by the chip (e.g. audio input) that you could
 not physically fit/be routed on the board?
4) PCB routing difficulties – are these common with similar SoCs or due to
 the unique RasPi size?
5) Do both HDMI and composite outs work simultaneously or does one
 have to be selected in software? (I’m guessing the composite video puts
 out whatever’s sent via HDMI downscaled to 480i …)
Thanks for keeping us informed, this is such a great project!

The GPU has a boot rom (i.e. hard coded into the chip) that understands
 FAT16 and FAT32. This was originally included in the boot options to allow
 easy demonstration of the devices (and to speed development as it only
 requires the copying of files to a SD Card and not reprogramming
NAND / NOR).

1/ As Steve H says: code in boot rom
2/ You need and SD card driver in bootrom
3/ We cut down on GPIO pins.
4/ These are common to most high density BGA package nowadays.
5/ Plan is to auto-detect HDMI and switch to composite if not present.
That code is not developed yet. I assume for composite we need
a ‘press key until you see a picture’ mode to go
trough all the world standards.

Is that not rather similar to how some Smartphones work.
Them download a jailbreaked software to their real computer
and place it on a sd card and then move that sd card to the
smartphone and start it and chose the SD card instead of the
built in software and then a Windows Smartphone can boot Android?
And then if one need go back one just reboot into windows.

My former work a new workmate there he had such on a Windows
OS phone. Samsung most likely. Worked easily but the boot time
is rather heavy for both OS. several minutes? unless I forget what
he told me. I trust it has to do with setting up radio communication
too so the smartphone is connected to the operator it belongs to?

I made a wallpaper using a picture of the Raspberry pi
circuit board.

Hopefully it will help to promote the computer.

Found this link to down load a torrent that maybe of some interest http://thepiratebay.org/torrent/6667294
Quote:
"The Raspberry Pi is a $25 Linux/ARM computer scheduled to be launched in November 2011. The purpose of Raspberry Pi (the name of both the computer, and the non-profit foundation that designs and sells it) is to help kids get access to computers and learn programming, in schools and the 3rd world, but the Pi (ARM11, 128/256 MB RAM, HDMI, USB...) is powerful enough for a variety of other uses (emulation, NAS, HTPC, Office work...).

More info here: http://www.raspberrypi.org/
FAQ: http://www.raspberrypi.org/?page_id=8
Wiki: http://elinux.org/RaspberryPiBoard

Description of this torrent by the VM's creator:
"VirtualBox Virtual Machine in which I have installed and configured Debian-i386, scratchbox2, qemu and the codesourcery toolchain so that it is possible to build software for the RaspberryPi (although no one actually has one, only a handful of alpha boards are in circulation right now).
This virtual machine should also be usable for other ARM based devices, especially if you have a rootfs and can seed the scratchbox2 environment (see http://russelldavis.org/2010/10/20/setting-up-scratchbox2-to-build-software-for-zubuntu/ & http://russelldavis.org/2010/11/03/mounting-a-raw-disk-image/ & http://russelldavis.org/2011/09/07/setting-up-scratchbox2-from-scratch-for-the-raspberry-pi/ )."

Please direct your questions/comments either to the VM creator's blog at
http://russelldavis.org/2011/09/10/virtualbox-vm-for-raspberrypi-development/
or to that VM's post on the Raspberry Pi forum at http://www.raspberrypi.org/?page_id=43&mingleforumaction=viewtopic&t=454.0
Comments here won't be closely monitored.

This is version 1.0 ( 2011-09-11) of the VM. "

This computer looks like a ripoff of an
idea from the raspberry pi people

Barry is working towards ARM with woof2 . . .
. . . had a go with woof2 myself . . .
http://puppylinux.info/topic.php?id=94

Next year Puppy will be 64 bit, ARM power will be available
and Saluki is solikely

It must be Christmas Cool

Thanks don570

HO HO HO one might say,
Do please save some of your hard earned Christmas money to buy one of these (when available).

The plan depends on your commitment.
Puppy optimised for ARM and Pi
and then as soon as it emerges we can transfer to a cheap and abundant complete mobile device.

I recently compiled qemu 1.0 and have the ARM version stashed away. If somebody wants to send me a reminder next week, I can post a pet when I return home.

Guys, be patient with the old fool Nooby now.
You know I am almost a Dummie when it comes
to getting code or set ups or how things work.

But the following seems totally wrong to me.

Maybe that user understand teh words differently
than what I do.

read here.
http://www.raspberrypi.org/forum/features-and-requests/boot-off-a-usb-stick

Angry Pict asks the thread and JamesH who is one of the admins answer

So can you put Puppy (or similar) on the SD and direct boot from it?


JamesH

Quote:
I believe that should be possible – this just a replacement of the debian (or whatever) compressed file with the puppy one on the root of the SD card.


How are Debian supposed to help Puppy to boot?

Debian do have code for ARM.
Puppy would need to be absolutely ARM-ified and that is not as easy
as it may sound to some of us.

Okay the Russian Puppy folks has come a long way but they still have
no working Windows Manager like JWM or any like that working?

What one would need is a Puppy that works like Debian do?
Debian are Multi User while Puppy are Single user and Puppy have
Aufs or what the name is. Layers that Debian don't have.

Knoppix also have AUfs or what term there is so puppy and knoppix
are unusual in that way?

Is it something that I miss? One OS can not start another
unless you have virtual boot for the second one but with so
little RAM that is not possible.

could someone explain what is going on. I doubt these two get
what is needed?

I know nothing about what the Russian team has accomplished
so I may totally have misunderstood. Maybe they have worked out
something very useful? That would be a good thing.

But that is not what the text here refers to. Another question.
Does the Russian Puppy then only have russian keyboard and display?
Or is it bilingual?

hi nooby

JamesH is just saying that to get puppy to work you simply delete the debian OS on the SD card and then copy to the SD card the Puppy OS.

ofcause we will need to have a working Puppy compiled for the ARM setup to get it to work.
