1.0 OVERVIEW
 
−
This document provides a quickstart guide on Mamba OpenWRT SDK V4.0
 
−

−
2.0 BUILDING OPENWRT
 
−
How to build the openwrt:
 
−
1. Setup the Linux server and install all packages for openwrt:
 
−
Refer: http://wiki.openwrt.org/doc/howto/buildroot.exigence
 
−
2. Make sure the server is connected to the Internet.
 
−
3. Preparation:
 
−
Extract the release source from tarball
 
−
# tar xzfv mamba-openwrt-v4.0.tar.gz
 
−
Extract the opensource (dl_v4.0.tar.gz) the dl folder
 
−
Update packages and luci for some advanced features ( such as
 
−
Web Management).
 
−
# cd mamba-openwrt-vX.Y
 
−
# ./scripts/feeds update packages
 
−
# ./scripts/feeds update luci
 
−
# ./scripts/feeds update routing
 
−
# ./scripts/feeds update xwrt
 
−
# ./scripts/feeds install -a -p packages
 
−
# ./scripts/feeds install -a -p luci
 
−
# ./scripts/feeds install -a -p routing
 
−
4. Configuration the openwrt:
 
−
# cd mamba-openwrt-vX.Y
 
−
To enable/disable packages manually:
 
−
# make menuconfig
 
−
You can also utilize the pre-config file (which enables Web Management):
 
−
# cp belkin/mamba_basic_config .config
 
−
5. Building the openwrt:
 
−
# cd mamba-openwrt-vX.Y
 
−
# make dirclean
 
−
# make V=s
 
−
6. Binary files after finish compile (or extract from release binaries):
 
−
# tar xzvf mamba-openwrt-vX.Y.bin.tar.gz
 
−
# cd mamba-openwrt-vX.Y.bin
 
−
# ls
 
−
md5sums
 
−
openwrt-mvebu-jffs2-128k.img
 
−
openwrt-mvebu-Mamba-rootfs.tar.gz
 
−
openwrt-mvebu-root.jffs2-128k
 
−
openwrt-mvebu-uImage-armada-xp-mamba
 
−
openwrt-mvebu-uImage-initramfs-armada-xp-mamba
 
−

−
Then put all the openwrt-armadaxp-*** to tftp server (/tftpboot folder)

−
3.0 HOW TO BOOT UP TO LINUX
 
−
1. Configure the ethernet:
 
−
Make sure the ethernet of board working, then we can get the files from tftp server for boot up Linux.
 
−
2. Set up environment variables required for Dual Boot (Primary Boot + Alternative Boot)
 
−
Mamba support Dual Boot with the following features:
 
−
+ Linksys and OpenWRT firmware use the same flash layout (mtdparts U-boot variable)
 
−
+ Linksys and OpenWRT firmware use the same kernel boot arguments (bootargs is the same and independent of the firmware)
 
−
+ Linksys and OpenWRT share the syscfg partition for storing configuration files.
 
−
+ Linksys and OpenWRT firmware can be flashed to Primary Boot partition or Alternative Boot partition (the ping-pong effect: when we upgrade firmware from Primary partition the new firmware is written to the Alternative partition, next bootcmd is set to Alternative partition. When we upgrade firmware from Alternative partition the new firmware is written to the Primary partition, next bootcmd is set to Primary partition)
 
−
The defaul U-boot environment variables are listed below
 
−
u-boot> setenv alt_kern_addr '0x3200000'
 
−
u-boot> setenv alt_kern_size '0x400000'

3. Burn the Firmwares to NAND
 
−
# to burn firmware image to Primary Boot partition
 
−
u-boot> run flash_pri_image
 
−
# to burn firmware image to Alternative Boot partition
 
−
u-boot> run flash_alt_image
 
−
4. Boot up firmware
 
−
# boot firmware image from Primary Boot partition
 
−
u-boot> run nandboot
 
−
# boot firmware image from Alternative Boot partition
 
−
u-boot> run altnandboot
 
−
 
−
5. If you want to reset the OpenWRT configuration to default, there are several ways to do that
 
−
5.1 Erase the whole syscfg partition in U-boot
 
−
WARNING: this will also erase the configuration data of alternative boot
 
−
u-boot> setenv mtdparts $default_mtdparts
 
−
u-boot> nand erase.part syscfg
 
−
Boot up OpenWrt again. The boot script will first show "ubifs sysfs not ready yet; using ramdisk", the boot script will automatically format and create a new empty syscfg partition to store configuration data.
 
−
5.2 Factory reset in OpenWrt Failsafe Mode
 
−
If the ubifs syscfg partition is already properly formatted, this method is preferred. It only tries to remove the configuration files and leave the alternative boot configuration files intact.
 
−
Boot up OpenWrt. When you see the failsafe prompt as below
 
−
"Press the [f] key and hit [enter] to enter failsafe mode "
 
−
Enter "f" and then "enter" (You can also enter the failsafe mode via the HW button, then telnet to the board to have console command line)
 
−
When you reach the command line interface. Run one of the two command below:
 
−
firstboot
 
−
# or
 
−
firstboot jffs2reset
 
−
NOTE: If the syscfg partition is not formatted yet. The above command will try to reformat and create a new empty syscfg partition.
 
−
Reboot the system
 
−
reboot -f
 
−
5.3 Factory reset in OpenWrt Normal Mode
 
−
If the ubifs syscfg partition is already properly formatted, this method is preferred. It only tries to remove the configuration files and leave the alternative boot configuration files intact.
 
−
Boot up OpenWrt normally. When you reach the command line interface. Run one of the two command below
 
−
firstboot
 
−
# or
 
−
firstboot jffs2reset
 
−
Reboot the system
 
−
reboot
 
−
 
−
5.4 Factory reset via WebUI
 
−
Login OpenWRT WebUI, go to System > Backup/Flash Firmware > Reset to defaults, press the "Perform Reset" button and choose "Yes" when the confirmation prompt appears
 
−
6. Overlay on syscfg partition sequence
 
−
If the syscfg partition is not found (it is defined in mtdparts variable at Uboot). OpenWRT will just mount read-only root filesystem. We cannot write to the read-only file system.
 
−
If the syscfg partition is found and is formatted as ubifs properly (it should have one syscfg volume inside the partition), OpenWRT will mount the syscfg partition and use the directory /openwrt_overlay for storing configuration files.
 
−
If the syscfg partition is found but it is not formatted properly (ubifs_mount failed), the system will first use ramfs (tmpfs) for overlay the root. Later in the init script (/etc/init.d/S95done), the system will try to recover from the ubifs_mount failed by formatting the syscfg partition. So on the second boot, we should not see this ubifs_mount issue again.
 
−
7. OpenWRT sysupgrade behavior
 
−
Mamba support two partitions for booting Linux. When doing OpenWRT sysupgrade
 
−
+ If current firmware boot is from Primary Boot partition (boot_part=1), the new firmware is written to Alternative Boot partition. Sysupgrade also sets two U-boot environment variables for next boot "bootcmd=run altnandboot" "boot_part=2". The system is rebooted and on next boot the system will boot from Alternative Boot partition.
 
−
+ If current firmware boot is from Alternative Boot partition (boot_part=2), the new firmware is written to Primary Boot partition. Sysupgrade also sets two U-boot environment variables for next boot "bootcmd=run nandboot" "boot_part=1". The system is rebooted and on next boot the system will boot from Primary Boot partition.

Setup Menuconfig

For WRT1900AC: 

The "Target System" in make menuconfig should be set to "Marvell Armada XP/370"
The "Subtarget" in make menuconfig should be set to "Mamba"
In "Target Images" in make menuconfig you should enable "jffs2"



Barrier Breaker

=

Barrier-Breaker/openwrt-armadaxp--jffs2-128k.img - prebuilt image based on OpenWrt Barrier-Breaker Barrier-Breaker/patch_submission_1.6.tar.gz - patch files for standard OpenWrt Package

OpenWRT git base revision: e97be7a104e5c809ae4638cf169823249a505698 OpenWRT svn base revision: 40006


Lokasi image

After the build completes the firmware image for the WRT1900AC will be 
located at:

./bin/mvebu/openwrt-mvebu-mamba-jffs2-128k.img


Update Image

How to update from Belkin/Linksys UI

  • Login into WRT1900AC local UI
  • Navigate to the Connectivity tab
  • Select Manual firmware update
  • Select image to load (e.g., openwrt-armadaxp--jffs2-128k.img)
  • Select Update firmware

After the firmware is updated, the unit will reboot, and the default ip address will be 192.168.200.1

The OpenWrt system is documented in docs/. You will need a LaTeX distribution and the tex4ht package to build the documentation. Type "make -C docs/" to build it.

To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system.
