How to Write Linaro ubuntu for arndale octa

I haven't visited the linaro official website for a long time. Today, I found many changes in the interface. The new version has a fresh style, and Linaro-ubuntu has updated the arndale-octa system to 14.3, in addition, some people on the insignal official forum said that ubuntu 14.3 can be installed on the desktop, so they can't wait to try it, but they found that they forgot how to download the root file system .. Really sweaty !!! Okay! Record down to save time! 1. download the latest linaro-ubuntu system from the official website. There are three versions: developer, nano, server, and desktop, because the official website does not support arndale-octa) 2. select a Version Download, take nano as an example (the actual root file system) http://www.linaro.org/downloads/ 3. download hwpack package, mainly including startup kernel and driver http://releases.linaro.org/14.03/ubuntu/saucy-hwpacks/arndale-octa 4. download linaro-media-create tool of linaro. I use ubuntu 12.04 _ x64 and download the linaro-media-create Source Code directly, currently, available linaro-image-tools can be obtained from the git repository. url:

Git: // git.linaro.org/infrastructure/linaro-image-tools.git

After the download is complete, add the local directory to the environment variable.

5. Burn writing

$ Sudo linaro-media-create -- mmc/dev/sdX -- dev arndale-octa -- hwpack hwpack_linaro-arndale-octa_20140323-616_armhf_supported.tar.gz -- binary linaro-saucy-nano-20140323-649.tar.gz

6. Insert the burned micro SD card into the SD slot of the Development Board, set to start from the SD card, connect to the serial port (through USB to serial port or direct serial port), turn on the power

7. Before that, use minicom-s to set the serial port. Generally, if the USB-to-serial port is set to ttyUSB0, the actual serial port is set to ttyS0.

8. the u-boot startup information will be printed on the serial port, but I don't know what is going on. It cannot be started automatically under ubuntu. It will be stopped automatically after UBOOT is started, you must manually enter a string of commands to start the system.

9. The detailed startup command is as follows:

$ Run addmac # Set the MAC address

$ Fatload mmc 0: 2 0x20007000 uImage # load the uboot recognizable kernel uImage to the memory 0x20007000

$ Fatload mmc 0: 2 0x22000000 uInitrd # load the root file system uInitrd to memory 0x22000000

$ Fatload mmc 0: 2 0x21f00000 board. dtb # load device tree board. dtb to memory 0x21F00000

$ Bootm 0x20007000 0x22000000 0x21F00000 # Start the system. Format: bootm kernel root file system Device Tree

10. Enter the system after startup

$ Uname-a # view the specific system version

$ Apt-get update # update

Note:

1. servers (server Version)
