IBR-DTN on OpenWRT on the Raspberry Pi

README.md

OpenWRT image for Raspberry Pi with IBR-DTN.

Steps to reproduce:

(This is an abridged version of OpenWRT Buildroot – Installation and Usage)

1. Get a fast machine with at least ~10 GB of free space.

2. For Raspberry Pi 1 and 2, you can use the latest release, 15.05 “Chaos Calmer”:

   • git clone git://git.openwrt.org/15.05/openwrt.git openwrt
   • cd openwrt

   Support for the Raspberry Pi 3 is still unreleased, you'll need at least r48967 (March 8 2016):

   • git clone git://git.openwrt.org/openwrt.git
   • cd openwrt

3. Get the software packages: ./scripts/feeds update -a; ./scripts/feeds install -a

4. Paste one of the following snippets to the file .config:

   • For Raspberry Pi 1, Zero or Compute Module:

     CONFIG_TARGET_brcm2708=y
     CONFIG_TARGET_brcm2708_bcm2708=y
     CONFIG_TARGET_brcm2708_bcm2708_RaspberryPi=y
     CONFIG_TARGET_ROOTFS_PARTSIZE=450
     CONFIG_PACKAGE_busybox=y
     CONFIG_BUSYBOX_CUSTOM=y
     CONFIG_BUSYBOX_CONFIG_TELNETD=n
     CONFIG_PACKAGE_pptpd=n
     CONFIG_PACKAGE_ppp=n
     CONFIG_PACKAGE_ibrdtn-tools=y
     CONFIG_PACKAGE_ibrdtnd=y
     CONFIG_IMAGEOPT=y
     CONFIG_VERSIONOPT=y
     CONFIG_VERSION_FILENAMES=y
     

   • For Raspberry Pi 2:

     CONFIG_TARGET_brcm2708=y
     CONFIG_TARGET_brcm2708_bcm2709=y
     CONFIG_TARGET_brcm2708_bcm2709_RaspberryPi2=y
     CONFIG_TARGET_ROOTFS_PARTSIZE=450
     CONFIG_PACKAGE_busybox=y
     CONFIG_BUSYBOX_CUSTOM=y
     CONFIG_BUSYBOX_CONFIG_TELNETD=n
     CONFIG_PACKAGE_pptpd=n
     CONFIG_PACKAGE_ppp=n
     CONFIG_PACKAGE_ibrdtn-tools=y
     CONFIG_PACKAGE_ibrdtnd=y
     CONFIG_IMAGEOPT=y
     CONFIG_VERSIONOPT=y
     CONFIG_VERSION_FILENAMES=y
     

   • For Raspberry Pi 3:

     CONFIG_TARGET_brcm2708=y
     CONFIG_TARGET_brcm2708_bcm2710=y
     CONFIG_TARGET_brcm2708_bcm2710_RaspberryPi_3=y
     CONFIG_TARGET_ROOTFS_PARTSIZE=450
     CONFIG_PACKAGE_busybox=y
     CONFIG_BUSYBOX_CUSTOM=y
     CONFIG_BUSYBOX_CONFIG_TELNETD=n
     CONFIG_PACKAGE_pptpd=n
     CONFIG_PACKAGE_ppp=n
     CONFIG_PACKAGE_ibrdtn-tools=y
     CONFIG_PACKAGE_ibrdtnd=y
     CONFIG_IMAGEOPT=y
     CONFIG_VERSIONOPT=y
     CONFIG_VERSION_FILENAMES=y
     

5. make defconfig; make world

   • optionally: use make -j world to build packages in parallel

6. Get a coffee. Or two. Or like SuSE says: Have a lot of fun.

7. You'll find the SD Card image in bin/brcm2708/:

   • openwrt-15.05.1-brcm2708-bcm2708-sdcard-vfat-ext4.img for Raspberry Pi 1/Zero/CM
   • openwrt-15.05.1-brcm2708-bcm2709-sdcard-vfat-ext4.img for Raspberry Pi 2
   • openwrt-r49395-brcm2708-bcm2710-sdcard-vfat-ext4.img (or similar rXXXXX) for Raspberry Pi 3
