The blue on-board LEDs should light in sequence and then continue to flash for the next 525 minutes (depending on the distribution used and the speed of the SD card).The beagleboard.org website has very clear instructions on writing a new system image to the BBB, so this section only details observations and additional steps that may be useful in achieving a successful upgrade.There are two versions to choose from: a version that runs directly from the micro-SD Card; or a version that writes to the BBBs on-board eMMC, called a flasher image.
The advantage of the eMMC version is that once it is written to the eMMC (which takes about 525 minutes) the BBB will boot in about 10 seconds from then on, and the micro-SD card slot will remain available for additional removable storage. For the remaining steps, the eMMC flasher image is chosen and Windows is used as the desktop operating system. Spi Serial Flash Programmer Schematic Heaven Download A FlasherIf you are planning to flash the eMMC with a new image, please ensure that you download a flasher image. The latest flasher images are available at::BeagleBoneBlackDebian and the latest image that is currently supported in this book is: BBB-eMMC-flasher-debian-7.8-lxde-4gb-armhf-2015-03-01-4gb.img.xz Creating an SD Card Image Using a web browser, download the image file to the desktop computer. If the archive extraction is successful, the result will be a single file with the.img extension (SD image file) of the form BBB-eMMC-flasher-distro-YYYY.MM.DD.img. Spi Serial Flash Programmer Schematic Heaven Install Win32 DiskUnder Windows, install Win32 Disk Imager from the Sourceforge.net website: sourceforge.netprojectswin32diskimagerfileslatestdownload. Extract the download to a folder that you can find again in the future, and execute Win32DiskImager.exe directly from within that folder. Please note that there is a similar tool for Mac OS X called Pi Filler. Place a micro-SD card that has sufficient capacity (ideally 4GB) into your computers SD card readerwriter and then start the Disk Imager tool. Once the disk imager software has started, it will not detect the SD card when it is inserted into the computer, so please insert the SD card first. Using Win32 Disk Imager, write the.img file to your SD card (using its drive letter for the SD reader on your desktop). This will take some time (about 515 minutes), which varies according to card speed, writer speed, and the distribution used. See Figure 2.A1 below for a screen capture of Win32 Disk Imager in action. When you are done, you will have a micro-SD card that you can use to flash your BBBs eMMC. Figure 1: The Win32 Disk Imager writing to the micro-SD card. Desktop Linux Alternative If you are not familiar with Linux then please ignore this sectionit is here for reference. Here are the steps required to create the SD card image under Linux: Find the micro-SD Card device (for example, mine is sdd). Flashing the BBB with the SD Card Image At this point you should have a micro-SD card containing a flasher Linux image. ![]() Disconnect the Ethernet cable and remove any shields and USB peripherals. Power off your BBB by physically disconnecting the USBpower cable. Hold the Boot Button (S2) on the top right (near the SD card slot) and, while holding this button, insert the USBpower lead to connect the power.
