The BeagleBoard-xM is a 8. There is basically all you need to build a simple desktop computer. Well, almost. Before being able to run anything useful, you have to first power the board and then build a microSD card with an useful distribution on it. First tip : connect your BeagleBoard-xM to your computer through the serial port. Buy an usb-to-serial adapter if needed, buy the serial wire if needed, but do not try to get things working blindly.

The xM was released rather recently. Consequentially, much of the online documentation that will come up on Google searches for "BeagleBoard" refers to the original version, and not the xM. Typically, the word "BeagleBoard", when used alone without modifiers, refers specifically to the original BeagleBoard and not to the BeagleBoard xM.
Major differences between the two are: 1. They have different inputs, so they require different peripherals, and 2. MLO, u-boot. Each of these are slightly different, so make a note of which revision you have. Finding all the right hardware Original BeagleBoard Links to the recommended collection of peripherals can be found on the bottom of BeagleBoard. BeagleBoard xM This website has a list of required cables for xM and as well as a guide to getting the Angstrom, Android, and Ubuntu OSs running on the xM, which require slightly different processes than to do the same thing on the original BB.
This will only work if you have an ancient desktop machine. Null modem cable will not work. The demo features the Midori web browser and a full GUI desktop. Additionally, all of the USB ports work with no additional setup. The demo Angstrom OS is surprisingly fast, even though it might sound like it has a lot of stuff on it. On the demo image everything is set up correctly for the version of BeagleBoard that you bought. Writing your own SD card even when using a prebuilt image can lead to a surprising number of difficulties, partly due to the many different revisions of BeagleBoard which exist.
It is best if you can simply keep the original card unchanged, and do your experiments on other ones. Be wary of thinking that you can simply back up the information on your desktop machine. To do so, connect a 5-pin Mini-USB cable to the board and to a computer at the other end. Also, if you connect some speakers or headphones to the audio output you should hear a burst noise when starting the board.
C boards, . For a more complete validiation of the rev. It is important to plug in the power last, because plugging in the monitor while it is powered up can cause damage. Applying power should make it boot up, first showing the BeagleBoard logo in the top of the screen, then an Angstrom loading splash screen, then to a screen saying "Automatic login", and if you do nothing, you should soon be dragging desktop icons around and surfing the Web with Midori.
Or you could drill out the plug. I used a hot needle for this purpose and it worked. First interaction with the board Connect the serial cable to the COM port in the beagleboard, and connect the other end to the COM port in the computer. U-Boot 1. In my case it was 0. Now we got the beagleboard shell! First command we wanna try is "help": OMAP3 beagleboard. If at some point you cannot enter text any more, verify that you have turned off flow control F and G should be set to No.
Also if after a reboot you do not see anything exit ctrl-A q and restart minicom SD card setup For a BeagleBoard xM specific step-by-step guide to setting up your SD card and installing Angstrom, click here. There are two ways of doing this, with a script or, through the fdisk "Expert mode". Formatting the SD card via the mkcard. You can find this by inserting your card and then running dmesg tail.
You should see the messages about the device being mounted in the log. Mine mounts as sdc. Once run, your card should be formatted. Changes will remain in memory only, until you decide to write them. Needed later below. Thus, if you got Numbers there are heads, 63 sectors, bytes per sector. So far so good, now we wanna create two partitions. One for the boot image, one for our distro.
Mark it as bootable. Calling ioctl to re-read partition table. The kernel still uses the old table. The new table will be used at the next reboot. Syncing disks. Linux will now be able to detect the new partitions. Additionally, download the modules modules Without these module files some peripherals, such as webcams, will not function. For certain images such as the images generated by the Narcissus build system , no separate uImage exists. Just copy the uImage-x. Now you must copy MLO, u-boot.
Do it in this strict order, since MLO must be in the first sectors of the card. If you downloaded the modules The newer versions have bootargs and bootcmd set to the correct values. Now we need to tell our BeagleBoard that we want it to boot from the SD card.
The only thing you have to do is to enable it by issuing the following commands on your beagleboard via the terminal. You can add it automatically by making some udev rules. See udev 7 for syntax. Note the mac address from "ifconfig usb0" Right-click the network manager icon in the panel. Click "Edit Connections Click the "IPv4 Settings" tab.
Change "Method" to "Manual" Add an address of Click "Ok" Enter your system password if prompted to allow changing of this system setting. You can now connect to your beagleboard using any VNC viewer and you should be able to access the internet from your beagleboard.
This allows the Beagle to operate as either a peripheral attached to a host computer e. To operate the Beagle as an OTG Host, you need a special cable -- plus you will need a power brick to power the Beagle, because it is now the host and must supply power to the peripherals.
This can be used for connecting e. That means it should have a power input which you can connect to a power socket. Further reading.
BeagleBoard-XM: Getting Started (cuz a Raspberry Pi would have been too trendy)
Installing Images for Beagleboard to SD card for Boot We are only interested in the kernel image and the filesystem archive, and we will simply replace the ones on the bootable SD card with these new versions. Note that we are assuming that you are starting with an SD card that actually already boots. Insert the SD card into the host PC and mount the boot partition and the rootfs partition. The mount point may vary from system to system. Replace the uImage kernel image file on the boot partition. If the SD card was previously bootable, it should now boot in the same way. Use Angstrom to build an SDK package.
Designed with the community inputs in mind, this open hardware design improves upon the laptop-like performance and expandability, while keeping at hand-held power levels. They can be used to repair corrupted cards or to create a backup version of the cards. They require a 4GB SD card for the image to fit. These are full desktop images. There is now a uENV.
Books Getting Started Beagles are tiny computers ideal for learning and prototyping with electronics. Read the step-by-step getting started tutorial below to begin developing with your Beagle in minutes.
