Re: Not just for kids

Re: No anti-static bag for 3B+?

The boxes that we pack Raspberry Pi 3B+ (and recent units of earlier models) into at Sony contain conductive card which have the same effect as an anti-static bag. In practice I suspect it's overkill: I remember back in the day (2010) testing BCM2763 (BCM2835 but in a 9x9mm 0.4mm-pitch package with ...

Re: OpenCL on the VideoCore IV!

Is a copy of you Masters thesis available online? I'd love to know a bit more about the challenges you encountered getting this to work. Particularly interested in your approach to writes to memory via the VDW (which as you observe is not the fastest thing in the world).

Re: Flash Player now available for Chromium

You cannot justify modification and use of closed source non-free software to work on an unsupported linux based armhf platform without an explicit licensing agreement. By most laws, this licensing agreement must be available and view-able in the files- It is not because there probably is no non-fr...

Re: RPI3 Clone?

That's weird. As you say, that's standard Chinese Raspberry Pi 3 packaging with a UK Pi ("Made in UK" on the front, KCE batch identifier on the back). Can you provide more detail on what isn't working?

That would be my hope. They really are building quite a lot of units.

Re: Information and Customer Respect

I thought it might be worth sharing a few thoughts on A+ and B+ availability here. When we launched Pi 2, demand for the B+ (and to a lesser extent the A+) fell dramatically, as expected. This is the first time we've ever had to manage a negative-going edge, but RS and Farnell had some stock of both...

Re: New 8MP Camera - Q&A thread

We've spent some time looking at some of the focus issues raised in this thread. We gone back through our PVT units, pulled units from both partners, and from two downstream distributors. The upshot is that across a sample of many tens of units we've not found anything that we wouldn't be comfortabl...

Be great if USB BOOT was actually already in the BCM2835 SoC of the ZERO :D No dice, I'm afraid. It's a straightforward technical operation: the underlying bootrom memory macro itself is common across all three chips and only the programming metal is different. However, in the words of Mr Burke, th...

Re: PiZero Roadmap

Does it require SoC support though; is there something more on the BCM2837 than is available on the BCM2835 or BCM2836 ? I honestly don't know. I thought the VideoCore and peripheral parts were the same ( apart from peripheral base address ) and the GPU is the only thing running when the SoC comes ...

Re: PiZero Roadmap

One more thing: previously it actually took more manpower to test a Zero than it did to test a B+/2B/3B. Sony have now implemented automated test for Zero so their maximum output rate (previously ~10ku a week) is now much higher.

A quick update. Raspberry PI Zero production is restarting in Wales next Monday after a hiatus to allow us to focus on Raspberry Pi 3 (a million units built and counting :D).

We've suffered a bit of a success disaster with A+.

Re: Deep learning neural networks on the QPUs

Also interested in seeing the code for this. As Simon says, I suspect you're using overlapping VPM areas from different QPUs. Btw, one golden rule (which you may already have figured out) is not to do reads from memory via the VPM/VDR - use the texture unit direct read mode instead for much higher b...

I'm seeing free shipping included in that price. If you look at the higher volume breaks, the shipping cost amortizes out and you end up back at $25.

Re: Hardware changes preventing booting of old SD card image

Yes - you'll need updated firmware if you want to boot your image on a 512MB Pi. We had to add entries to the table of supported SDRAM devices to cope with the new Samsung 4Gbit part.
