RPi with 512mb Memory?

Just received via email from element14:

The New Raspberry Pi is here!

We are thrilled to announce the launch of a new 512MB board version of the Raspberry Pi. Now packed with double the RAM, the new Pi  is suited to multimedia, high-memory and mobile applications, including a future version of an Android 4.0 operating system. Order yours here! We're really looking forward to hearing  what plans you have for your new Pi.  So, we've launched a blogging competition asking what you're going to do with double the memory. Join in and submit an entry on the RPi forum and you could win an awesome prize!

Hello Jamodio. . .

I'm happy to report I've just purchased the new Raspi, model B with 512Mb. Nice that it was $35 (+6 to ship) from the Newark site. Receipt said "1 available to ship today". Great way to start a Monday. . .now if only the line on my order history for the Gertboard would say SHIPPED, we'd have a perfect day!

I ordered with Newark a week ago, and I just got this e-mail:

"Dear XXX,

We're excited to inform you that the Raspberry Pi 256MB that you recently purchased has been automatically upgraded to the brand new 512MB at no additional cost. The new Raspberry Pi has double the RAM memory, which more than doubles the user accessible memory. To find out more about the technical benefits of the new Pi 512MB, see the highlights below or Click Here. We hope you enjoy the speed of your new Raspberry Pi-now on its way to you.

Visit our accessories page today and create your own starter kit. Learn more and see the Raspberry Pi in action at element14 community. "

That said, my order status page still says backordered with a ship date of Nov. 1, and this e-mail says it's "on its way," so I'm not quite sure what's going on.

I suspect that, currently, over-exuberance is trumping stock levels to fulfill the level of enthusiasm.

Well it seems that newark have/had some boards in stock, got confirmation that it was shipped via UPS, expected delivery on 10/17.

Well, I'm in the UK and when I ordered (14th October)  there were 300 'ready for next day delivery' - so I'm wondering why mine is still 'processing' on the 16th !

No doubt it will arrive soon and if not, I can wait.

Hi,

I will pass your message to Newark Customer Service so they confirm with you delivery date.

Thanks,

Hello jamodio - I just received an email this morning saying my new Raspi had shipped! I expect it will arrive tomorrow. Strange stuff )

Hmm - will have to wait and see what turns up in your shipping package to be sure. I ordered my Pi from element14 New Zealand - looks like it was fulfilled from Element14 Australia.

When i noticed they had a couple of thousand turn up in stock, i called (yesterday) to ask if they were the new improved spec models - and was assured yes i would revieve one of the newer models.

It turns up by courier today, and disappointed to see that despite being a newer board manufactured in the UK, it seems to have a 256meg chip fitted.

I guess i ordered the 256meg version, so i shouldnt be so disappointed - but actually am rather gutted as i want it to run XBMC - which would certainly benefit from the extra memory...

guess i should just have cancelled and re-ordered. Grrrr.

Hi Pete

Looking at your post I would also think you should have received a 512MB unit

You may have doen this but can you run the following command and check the code number that the board returnsd

cat/proc/cpuinfo

If you’re running revision 1.0 you will see code numbers 2 or 3

If you're running revision 2.0, 256MB you will see code numbers 4 or 6.

If you are running the Raspberry new Pi Model B (512MB) Revision 2.0 you will see code numbers 13 or 14

Thanks

Mike

Will there be a 256 rev2 with code 5?  or has this been abandoned?

The Rev 2.0 board just arrived, Samsung part number is K4P4G324EB-AGC1, board says made in UK, no indication on the box about version or memory size. FPC connectors look cheaper than the ones on previous boards.

Good thing, the LDOs are from ON Semi and not from cheap-o-china.

I guess you know that is a 512mb version.

Obviously I do.

Just noticed on my Rev2 512mb that if you touch the USB controller chip, it shorts out the USB circuit. Is this a flaw? Or is it just it should not be touched?

My 512Mb Pi arrived yesterday, will only have a chance to play at the weekend. Will try touching the usb controller and see what happens.

Heck, I like to live dangerously, might touch it with my tongue and see what happens !

The should start producing the boards with raspberry scent on the silk screen ink

Sounds like a flaw.  As long as you've touched ground somewhere on the board (e.g., the USB or Ethernet shell) before lightly touching a chip package, it shouldn't have any effect other than perhaps a burned finger-tip.  If the USB chip fails if you touch it, IMO the most likely cause is a hair-line break in a PCB trace so that if the board flexes the trace opens.  It could also be an iffy solder joint, though those are more likely to open when you're not pressing down on the chip.

You could have an effect if you touch the LAN9512 crystal oscillator pins.  Also check the solder joints on crystal X1 which is on the back side of the PCB near the LAN9512.  Crystals are sensitive to being touched, especially if not well soldered.

Can you be more specific about "shorts out the USB circuit"?  What's shorting to what, or are you just saying USB stops working, and if so, for how long?

Oh, and what's under the RasPi?  If it's on a mildly conductive surface pressing down could cause mischief.

Mine was waiting for me when I got home last night. I haven't had time to do anything with it yet. What OS are you going to put on yours??

Fun stuff. . . learned about it, bought it, and got it - - all within a week!  Just have to wait a couple of days to really get in to it.

I wonder if there's something squirrely with latest RasPis.  There's someone with a similar unexplained USB/Ethernet problem at the RasPi forum.  I wonder when the rev 2 schematic is going to get published?  Gerbers would be nice too.

Same bloke I'm reckoning.

Just received a pi that I ordered monday of this week, the part number on the samsung chip is K4P4G324EB-AGC1, which some one indicated above is the 512 board, although

dmesg | grep -i mem

reports

[    0.000000] Memory: 192MB = 192MB total

[    0.000000] Memory: 188976k/188976k available, 7632k reserved, 0K highmem

cat /proc/cpuinfo

reports

and

top

reports

KiB Mem:    189100 total

none of this points me to believing this is the 512 board that I was led to believe I was buying

the bag it came in says

MFR# RASPBRRY-MODB-512M

Am I missing something?
