Editor's Notes
- #1 These are the topics that will be covered today. We wanted to take you on the journey we took as we created the BeagleBoard from start to finish with the hope that you will learn from what we did, both good and bad. Our hope is that you can use this information to help you on your own journey as you develop exciting products using the OMAP3 line of processors. The Name topic will tell you how we arrived at the name for the BeagleBoard. The Specification was an eye opening experience fro us and helped us to develop the center of our overall strategy. As we started the Schematic, we found several ways to reduce our overall design risks to meet our goals. The PCB Layout was full of opportunities to learn as we developed with the fine pitch devices on the BeagleBoard. After the PCB Layout experience we were confident that we had done it right, but we were not prepared for the underlying traps of the PCB design. As we started the Testing phase, we found that we needed to implement additional tests to make sure we were catching all of the issues. We really weren’t sure what the Support phase was to be like, but it had some surprises for us. We then took all of the Lessons Learned and rolled them into the next version of the BeagleBoard.
- #2 Ah, what to name it. Names have a way of hanging around.
- #3 We are ruled by acronyms. So, in order to be taken seriously, we needed to make Beagle a real American acronym!
- #4 There were many things that we learned from building the BeagleBoard. Our hope is that this presentation will allow us to pass on what we have learned as well as show you how you can learn even more by building the BeagleBoard.
- #5 The PowerVR™ SGX Series5 Graphics Processing Unit (GPU) IP core family is a series of highly efficient graphics acceleration IP cores that meet the multimedia requirements of the next generation of consumer, communications and computing applications. PowerVR SGX Series5 architecture is fully scalable for a wide range of area and performance requirements, enabling it to target markets from low cost feature-rich mobile multimedia products to very high performance consoles and computing devices. Package on package (PoP) is an integrated circuit packaging method to combine vertically discrete logic and memory ball grid array (BGA) packages. Two or more packages are installed atop each other, i.e. stacked, with a standard interface to route signals between them. This allows higher component density in devices, such as mobile phones, personal digital assistants (PDA), anddigital cameras. Package-on-Package or (PoP) memory was created as a way to reduce the physical size of the memory sub-system on a single board. The basic idea is to stack two BGA devices one on top of the other as shown above. PoP Memory has Several Advantages Including: More reliable manufacture because the memory sub-system can be assembled separately from the final system. Higher memory cycle speeds due to shorter connection lengths. Small size This type of memory is used in handsets and other types of portable devices and is also making it’s way into mid-level products as well.
- #7 We spent weeks trying to figure out what could go. The challenge was to get rid of everything we can but remove nothing! Everything we put on the board will limit us. It means that we support one Ethernet instead of 10s of Ethernet devices. One Wi-Fi device instead of 10s of devices. We decided to let the mass producers of these devices drive the cost out of the solution. Anything we put on the board would have a fixed cost. So, we came up with the concept of “bring your own”.
- #9 The USB 2.0 High Speed On the Go connection on beagleboard is very flexible. BeagleBoard can act as a ‘device’ when connected to a PC via USB. This can be used to provide power to BeagleBoard and to emulate a network connection on BeagleBoard. Via the network connection emulation, you can ‘telnet’ into the board that is loaded with an operating system and use it to perform software development, even without the serial cable. This is useful once you have initialized the board with a working file system, or if a USB-based loader is generated in the future. As another scenario, BeagleBoard can act as a ‘host’ when connected to a USB hub, allowing almost endless array of USB peripherals expansion. This will requires a mini-A to standard-A adapter cable. You can use a standard 5V power supply plugged to the barrel power connector to power BeagleBoard when the USB is being used as host.
- #10 Now let’s highlight the benefits to you of the low power consumption of BeagleBoard. Low power means NO FANS are needed, which means Silent operation….you can use it in your media center without annoying fan noise. Low power means USB cable power, such that you can take BeagleBoard with you on the road with your laptop or a cell phone charger. NO additional power supply needed. Low power means no heat sinks and smaller size and lower cost board. Or, if you choose, Alternate power means you can use the USB Host for expansion. The alternate power can even be derived from USB!
- #11 BeagleBoard has comprehended the need for flexibility of channels for the processor to boot, to avoid inefficient lock ups. Because boot code is in ROM, it is always there, even if the flash is erased. However, you want to modify BeagleBoard code, right! Of course! So when attempting to modify some non-open devices (other than BeagleBoard), you may end up making your device unable to boot without professional tools and therefore becoming as useful as a ‘brick’, thus the term ‘bricking’. To solve this, and overcome “bricking”, the BeagleBoard User button allows you to change boot sequence, for example, boot from USB instead of from NAND. So you never have to worry that bad content in the NAND will prevent you from being able to boot your BeagleBoard, with your new boot code in an SD card, for example. The button’s status is also available to software at times other than boot, so you can make use of it in applications. The reset button is also configurable in software, if you wanted to use it for another purpose.
- #13 This illustrates the “signal chain” for electronic devices. What “comes in” is the real world signals. Analog is shaded in pink; there are lots of analog components needed to condition, convert, manage power, and connect to DSP and send back to real world in an understandable format. DSP (yellow) provides the signal compression and decompression and processing that makes systems smarter. TI is the world leader in programmable DSP and will continue to focus on DSPs. TI has across-the-board solutions for each component of the signal chain. Customers don’t care that we are #1 or #2 in each area (although we are). They care about their needs – what can we do to solve their problem? When we solve their main problem (e.g., provide ultra-low power for a medical device), we can look at their other needs (e.g., faster conversion from digital to analog) and help them be more successful. Some competitors may focus on a specific area (e.g., interface) and cannot provide across-the-board solutions for customers.

- #23 Secure Digital (SD) is a non-volatile memory card format developed by Panasonic, SanDisk, and Toshiba for use in portable devices. It is widely used in digital cameras, digital camcorders, handheld computers, netbook computers, PDAs, media players, mobile phones, GPS receivers, and video games. Standard SD cards have a maximum of 4 GB capacity, even though the official standard allows for ≤2 GB.[1] The capacity range for standard- and high-capacity (SDHC) cards overlap, beginning at 4 GB, but SDHC's upper limit had reached 32 GB as of mid-2009. SDXC (eXtended Capacity), a specification announced at the 2009 Consumer Electronics Show, allows for up to 2 TiB cards. SD cards are based on the older MultiMediaCard (MMC) format, but have a number of differences: The SD card is asymmetrically shaped in order not to be inserted upside down, while an MMC would go in most of the way but not make contact if inverted. Most SD cards are physically thicker than MMCs. SD cards generally measure 32 × 24 × 2.1 mm, but as with MMCs can be as thin as 1.4 mm if they lack a write-protect switch; such cards, called Thin SD, are described in the SD specification, but they are non-existent or rare in the market as most devices requiring a thinner card use the smaller (and thinner) versions of SD: miniSD or microSD. The card's electrical contacts are recessed beneath the surface of the card, protecting them from contact with a user's fingers. SD cards typically have transfer rates in the range of 80–160 Mbit/s, but this number is subject to change, due to recent improvements to the MMC standard.[5]
