That's odd. I know for a fact that Farnell have plenty in stock:

Re: A new Scratch; pre-alpha-this-will-hurt release

Posting this on Tim's behalf now I've had a chance to upload his tarball to the Raspberry Pi servers. A new release of NuScratch is now available for your testing pleasure. High- and low-lights include: The menus, both menubar and pop up, work (though some actions caused by them don’t yet). Building...

Hi Gerhard

Re: CODEC Ordering confusion

You can just use the comma-separated list in all of your config.txt files. The system will search through the list until it finds the right license for the particular board you're booting on.

Re: USB Port Current Boost (solved)

I just received my 2nd R-Pi, this one from stock (yay MCM Electronics) which took just a week to ship from Ohio to California. I was pleased, but surprised to see that the USB fuses F1, F2 are now just 0-ohm jumpers (photo below). I was able to confirm they measure less than 0.1 ohms. Is this the n...

Re: An nbench challenge

Surely posting benchmarks on steroids might be counterproductive, especially regarding the "I never bother to RTFM" crowd. By all means benchmark it in a series of real-world situations, but I feel that wringing the snot out of it (and possibly invalidating the warranty) is totally missing the poin...

Re: An nbench challenge

Maybe worth adding

-mcpu=arm1176jzf-s -mtune=arm1176jzf-s

to the CFLAGS in the Makefile, and trying -O2 and -Os instead of -O3.

In case you hadn't guessed, I'm travelling without a Raspberry Pi, otherwise I'd be playing with this myself as well :)

Re: An nbench challenge

Can you share the compiler flags you used to get these results, and maybe the resulting binaries? Some initial thoughts:
  • gcc 4.7 seems to make a significant difference versus 4.6
  • We do well versus Cortex A8 on floating point, less well on memory and integer

An nbench challenge

I'm going to put together a blog post fairly soon comparing our performance with various other single-board computers. On the CPU side, I'm intending to use nbench , as results for other systems are widely available. I don't want to sell Raspberry Pi short, so I'm appealing for help to find the buil...

Re: Faulty Pi?

When the screen goes blank, are you still able to ping the Pi from a remote machine? If so, it's possible you may need to adjust the HDMI drive strength (search for config_hdmi_boost for more info on this).

Re: Red LED on Faint Green LED

The problem with adding more debugging to the loading process is that you're falling at the very first hurdle - before even the first-stage GPU bootloader has been read from SD card. This means you're under the control of the on-chip boot ROM which is, well, a ROM. We've had a bunch of requests for ...

Re: Red LED on Faint Green LED

Obviously if you get the 1 board in 500, you personally experience a 100% failure rate, which is less than ideal. So far we've been very impressed both with our users' perseverance (a false RMA rate of 1 in 1000 is remarkable) and with both companies' RMA procedures. As you note, people with faulty ...

As you can see, we have an enormous amount of fill-rate, which helps when we\'re trying to render content like Samurai at 1080p. We\'re comfortably ahead of Tegra 3 in 3d performance.
