Small board (81x91mm) with minipci module.

This device works with gemini images. If you would like to use USB ports you should recompile yourself following th OpenWRT howto and customize the kernel as described here

1. → obtain.firmware
2. → Install it

This section deals with how you install OpenWrt from a device freshly opened. Plus the steps required such as reset to factory defaults if the device has already been configured

Note: Reset router to factory defaults if it has been previously configured.

• Browse to http://192.168.0.1/page.cgi?page=maintenance
• Upload .bin file to router
• Wait for it to reboot
• Telnet to 192.168.1.1 and set a root password, or browse to http://192.168.1.1 if LuCI is installed.

• Set your PC's IP to 192.168.1.254
• Open a TFTP server and place in his root the image with this name: fwupdate.bin
• Power-on your WBD-111 holding reset button
• Wait about a minute per megabyte (default image 3-4minutes)

If you have attached a serial interface, be aware that the speed of the serial Port ist switched to 9600N81 on kernel boot. This only happens for kernel boot's directly after flashing the router via TFTP (very likely a uboot bug).

SYSUPGRADE DOESN'T WORK ON GEMINI PLATFORM → generic.sysupgrade

If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you CANNOT upgrade using the mtd command line tool. You should bask to the original firmware then "upgrade" with the new image.

Not possible.

Manual Update using mtd works, you have to write the kernel image and the squashfs image in two steps:

Upload the kernel Image an the squashfs image:

$ scp bin/gemini/openwrt-gemini-wbd111-zImage bin/gemini/openwrt-gemini-squashfs.img 192.168.1.1:/tmp

Write the Kernel Image

root@OpenWrt:/# mtd write /tmp/openwrt-gemini-wbd111-zImage kernel

Write the SquashFs Image and reboot

root@OpenWrt:/# mtd write /tmp/openwrt-gemini-squashfs.img rootfs

You will most likely loose your config, since the rootfs_data will most likely overwritten

→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

The default network configuration is:

→ generic.failsafe

If you forgot your password, broken one of the startup scripts, firewalled yourself or corrupted the JFFS2 partition, you can get back in by using OpenWrt's failsafe mode.

NOT TESTED

• Unplug the router's power cord.
• Connect the router's LAN1 port directly to your PC.
• Configure your PC with a static IP address between 192.168.1.2 and 192.168.1.254. E. g. 192.168.1.2 (gateway and DNS is not required).
• Plug the power on and wait for the DMZ LED to light up.
• While the DMZ LED is on immediately press any button (Reset and Secure Easy Setup will work) a few times .
• If done right the DMZ LED will quickly flash 3 times every second.
• You should be able to telnet to the router at 192.168.1.1 now (no username and password)

NOTE: The root file system in failsafe mode is the SquashFS partition mounted in readonly mode. To switch to the normal writable root file system run mount_root and make any changes. Run mount_root now.

1. Forgot/lost your password and you like to set a new one

passwd

1. Forgot the routers IP address

uci get network.lan.ipaddr

1. You accidentally run 'ipkg upgrade' or filled up the flash by installing to big packages (clean the JFFS2 partition and start over)

mtd -r erase rootfs_data If you are done with failsafe mode power cycle the router and boot in normal mode.

• Reset Micro Switch behind the plastic casing
• Green GSM LED
• 100 MBit LAN Port
• Green LAN LED
• SIM Card Slot
• Green Power LED
• Power Connector, 3.9mm outer diameter, 1.1mm inner diameter. Polarity does not matter, the board has a bridge rectifier build in the power input

• Hardware modification: 2,5mm TRS connector for a 3.3 Volt serial console
• GSM AUX or GPS Antenna (depending on the GSM module settings)
• WLAN AUX

Note: This will void your warranty!

• To remove the cover you should simlpy unscrew the 4 screws!

How to connect to the Serial Port of this specific device:

The Serial connection can soldereded to J4, the connector on the top of the PCB photo's.

→ port.jtag general information about the JTAG port, JTAG cable, etc.

As far as known, the platform has not JTAG interface.

→ debugging

1. you could read about bootloader in general

1. as a beginner, you really should inform yourself about soldering in general and then obtain some practical experience!

• prepare your kernel (this step is uncommon, but it's indispensable for wbd-111):

make kernel_menuconfig

In this step you should include the right usb drivers:

**Device Drivers --->**
**USB support --->**
Mark as "built in" (*) **Support for Host-side USB**
Mark as "built in" (*) **EHCI HCD (USB 2.0) support**
esc-esc esc-esc... save!

To check if you have selected the correct driver after flashing image

dmesg | grep -i ehci-fotg2xx

should return

ehci-fotg2xx ehci-fotg2xx.0: Found Faraday OTG 2XX controller (base = 0x68000000)
ehci-fotg2xx ehci-fotg2xx.0: FOTG2XX EHCI Host Controller
