Re: Programming the ARM chip

if memory serves me right some sample code has been provided, Possibly I've missed that too (if so, a link would be very much appreciated), but I'm not aware of any datasheet or specific example code showing how to configure the video hardware directly and do basic stuff like setup screen modes and...

Re: Programming the ARM chip

The Broadcom documentation gives info on addresses to use for the frame buffer for display. Really? This is exactly what I've been waiting for but in the BCM2835 pdf file I have it doesn't mention anything at all about accessing the hardware directly to display something on screen. Is there a new a...

Re: Boot menu to choose distro and/or memory model of choice.

<t>A simple boot menu is the kinda thing I'd like to do direct from ARM assembler, but it's not possible yet as there's no documention on how to do basic stuff like put text on screen or read input from the keyboard by hitting the hardware direct.<br/> <br/> Hopefully once the RasPi is out there the...

Re: Ebay UK £5 Voucher = Free SD card!

Ebay UK have a £5 promotion code here:

so if you're quick you can pick up a free 8GB SD card, just search for one at less than £5 with free shipping.

Re: A plea to the Foundation re. MPEG-2

My old IBM Thinkpad 600e (Pentium II @ 366 Mhz) could decode SD MPEG2 in software and play DVD movies at full speed, so it seems likely that the RasPi hardware is capable of doing the same, though it may need an optimised decoder as mentioned above.

Re: What are these boards for?

Dump the eprom if you can, that will likely give some clues.

The big IC could be an 8051 based microcontroller, it has the same package type and number of pins and was used extensively in eg. car ECU's in the 90's.

Re: Programatically lock SD Card to hardware unit?

I'd epoxy the entire area of the SD card slot and/or solder a PIC to the RasPi GPIO's as a dongle.

Re: Console output after GPU handover?

<t>This will be simple to implement in ARM code once we know the hardware addresses for setting up the "dumb frame buffer", or even the addresses of the basic setup routines in the GPU "blob" if we can't access the hardware directly. Hopefully this info will become available soon after the launch of...

Check Farnell again, I think they may have recently removed the minimum order value. It's not appearing for me atm anyway.
