Installing OpenWRT on a Raspberry Pi from Ubuntu!

Create Boot SD Card

  • Download OpenWrt Linux distribution for Rpi from here
    – Choose the image according to the amount of RAM you want to give to the system (_128, _192, _224) or according to the Pi memory size, if 256MB choose the _128 else you can choose _192 or _224
  • Flash Rpi SD Card
    * Format the SD Card using the Disk Utility application in Ubuntu (Select your SD card and format as FAT)
    * Identify the SD card card
                          sudo fdisk -l
    you will see something like this
    aa    So, the SD card is /dev/sdb1 (if unsure of your computer’s naming convention, run prior to inserting SD then again after to identify mounted card)
    OR     use df -h command 
    bb
    *     Flash the SD card
                          cd Downloads/
                           replace “Downloads” with the location of the downloaded .img file
                                 
                          un mount the SD card   
                          umount /dev/sdb1

                          write the image to the SD card
                           sudo dd if=openwrt-raspi.img of/dev/sdb1 bs=2M
                           replace “openwrt-raspi.img” with the img name, and “/dev/sdb1” with the device name detected from “fdisk -l” or “df -h”. The process of flashing the SD card will take around two or three minutes. Once the SD card has been flashed, you will see a further message in the terminal window.When “dd” finish writing the image to the SD card a message showing the number of bytes copied and the copying rate will appear indicating the end of flashing process.* Unmount the SD card and it is now ready for use in your Raspberry Pi.

Boot the Pi

  • Insert the SD card and plug in the power —more details here (Skip installing new distribution, startx command won’t work too)–
