USB Device Firmware Upgrade (DFU) is an official USB device class specification of the USB Implementers Forum.

It specifies a vendor and device independent way of updating the firmware of a USB device. The idea is to have only one vendor-independent firmware update tool as part of the operating system, which can then (given a particular firmware image) be downloaded into the device.

In addition to firmware download, it also specifies firmware upload, i.e. loading the currently installed device firmware to the USB Host.

The current version is 1.1, it can be found for free download at http://www.usb.org/developers/devclass_docs/DFU_1.1.pdf

Despite its clear architecture and DFU being an official USB standard, very few companies are known to have implemented it in their products. In the Free Software / Hardware area, most notably the OpenPCD project has used it for their Free RFID readers.

Openmoko and USB DFU

Since Openmoko is a big supporter of open standards and protocols, it has chosen USB DFU as the way to do 'firmware' (actually, general software) updates on its official devices.

USB DFU host utility

Please see dfu-util for more information.

USB DFU on the Neo1973

The DFU implementation is part of our version of the u-boot bootloader.

You can use it with any USB DFU 1.1 compliant utility. We also have developed our own dfu-util program.

Type of DFU Download

The Neo1973 has enough SDRAM to accomodate a download mechanism according to Chapter 6.1 Mechanism '1.' (to receive the entire image into a buffer and perform the actual programming during the manifestation phase). We are using this mechanism for the u-boot partition to prevent users from 'bricking' their device if something goes wrong during the transfer.

For other partitions (kernel, rootfs, ...) however, future devices will have more NAND than SDRAM. Thus, we implement a download mechanism according Chapter 6.1 Mechanism '2.' for all non-bootloader partitions.

USB DFU Interfaces

The DFU in the Neo1973 has a USB Alternate Interface name 'RAM 0x32000000' number 0 for downloading executable code into RAM (address 0x32000000) and executing it. The rest of the Alternate Interfaces are for each internal NAND flash partition.

U Drive is a central file storage for users that provides students, faculty and staff with a place to store files that can be accessed from anywhere, on- and off-campus.

U Drive files are available via the network in real time, from any computer on campus, both personal and institutionally owned. Windows, Mac and Linux computers are supported.

Off campus, users can access their files via standard internet protocols such as Secure File Transfer Protocol (SFTP). No additional software is needed to sync files, and desktop software (such as SPSS or Adobe products) can open and save files directly from the U Drive from campus.

Announcements

There are not currently any announcements for U Drive.

Amount of storage

• Students: Students can store up to 50 GB of data, which is automatically backed up. This service is activated automatically for all students; you can use it right away.
• Faculty and Staff: Faculty and Staff are allotted 50 GB of data, which is automatically backed up. If you need more space than that, your quota can be increased with a UW Budget number on the Manage Your UW NetID Resources Web page.
  • Note: This service is not appropriate for storing regulatory-protected data, or sensitive information that may be subject to compliance regulations. See Information Security and Privacy Laws and Regulations for more information.
• Sponsored: Sponsored accounts are allotted 50 GB of data, which is automatically backed up. If you need more space than that, your quota can be increased with a UW Budget number on the Manage Your UW NetID Resources Web page.

Activate and manage your storage

U Drive is automatically activated for all students, faculty and staff. If you wish to manage your account manually, you may do so at the UW NetID Service Management page. Follow these steps from your browser to activate or deactivate this service:

1. Navigate to your Manage Your UW NetID Resources Web page.
2. Click on “Computing Services.”
3. Check the box next to “Central File Storage.”
4. Click on “Subscribe” or “Unsubscribe” to update your account.

Faculty and staff can also purchase additional storage from the UW NetID Service Management page with a UW budget number. Rates are available in the UW-IT Service Catalog.

Accessing U Drive

How you access U Drive depends on if you are on the UW network or not.

• From on-campus while on the UW network: If you are on the UW campus and using the UW Wi-Fi network, the eduroam Wi-Fi network, or a computer plugged into an UW network Internet access point, you can access your U Drive via SMB.
• From off-campus or while not on the UW network: If you are off campus, or not connected to the UW network, you can access your U Drive via SFTP or via SMB while using Husky OnNet to virtually access the UW network.

Accessing U Drive via SMB

Connecting via SMB requires that you be either connected to the UW network or using Husky OnNet to virtually access the UW network. If your U Drive service is active, you are ready to access your storage on U Drive. The most common way to access the U Drive is by opening it on your computer like any other disk:

Windows

1. Press Windows-R (Press the and R).
2. Type udrive.uw.eduudrive; Click OK.
   
3. When prompted for Username and Password, enter as NETIDusername, followed by your UW NetID password; Click OK.
   

Mac OS X

1. Open “Finder.”
2. Press Command-K (or Go -> Connect to Server from the menu).
3. Enter: smb://udrive.uw.edu/udrive
4. Click Connect.
   
5. When prompted enter your UW NetID username and password.
   

Linux

Connect to smb://udrive.uw.edu/udrive

Accessing U Drive via SFTP

You may access U Drive via the SFTP protocol from any Internet connection, on- or off-camps. This allows a more traditional way of moving files to and from the U Drive, and does not have network restrictions. Basic instructions are below.

Secure FTP (SFTP) Programs

Free SFTP programs are available from a number of sites on the Web. A common program is Filezilla, but others are available. You may wish to check with your local support team to see if there is a preferred software package. When downloading such programs, be VERY CAREFUL to read the complete text and especially the text for any checkboxes before clicking the download button. Otherwise you may unintentionally give the site permission to download and install other programs or adware; many such programs are malicious and very hard to remove.

Generic Transfer Settings

The following table outlines the basic connection settings which can be used with SFTP programs.

Generic Connection Settings

Get Backups of your files

The U Drive service provides access to previous versions of your files providing one version a day for a week, one version a week for a month, and one version a month for 3 months. These versions of your files are called snapshots. All of your U Drive snapshots are stored in a directory (location described below) called “udrive”, and the name of each snapshot directory reflects the date it was created.

To access your snapshots from on-campus, follow the instructions above for “accessing your U Drive” to open the following:

• Windows Users:
  udrive.uw.edusnapshots
• Mac OS X and Linux users:
  smb://udrive.uw.edu/snapshots

Uwb Dfu Driver

To access snapshots from off-campus:

• Follow the instructions above, but double click on “snapshots” rather than “udrive”

Sharing and collaboration

The Central File Storage with the UW, U Drive, are only accessible to you — it is not a shareable drive. Some alternatives that are available for file sharing are UW Google Drive, Dropbox, or UW OneDrive for Business.

Transitioning between statuses

Transitioning from Student status to Faculty/Staff:

In the case that default student quota is ever greater than the default staff quotas, limits will be lowered in the transition if these conditions apply:

1. If a user’s usage is “well below” the new limit, their quota will be silently dropped to the new limit. “Well below” is defined as “The usage plus the lesser of 25% of the limit or 250 MB is less than or equal to the new limit.” In particular, a user with zero usage and a new limit of zero will be silently dropped to zero.
2. If the user is near (aka “not well below”) or above the new limit:
   1. A warning email is generated explaining that the limit is going to be reduced in two weeks.
   2. When the deadline arrives, the quota is lowered.
   3. Prior to the deadline, the user’s quota is dropped to their current usage plus the 25% / 250MB grace value rounded up to the next gigabyte whenever their usage is “well below” the existing limit.

Transitioning to an Active Student affiliation:

Students’ quotas are set to 50GB as long as the total student usage of the service does not exceed the 15TB limit. To manage this quota after transitioning, go to the Manage Your UW NetID Resources Web page.

Transitioning from Faculty/Staff to Student status:

In the case of the Faculty/Staff having greater than 50GB for their quota, limits will be lowered to 50GB and changes may occur depending on how much of the quota is being used. When a Faculty/Staff changes their affiliation or adds an affiliation for Student status, they will be able to manage their storage quota for their U Drive services on the Manage Your UW NetID Resources Web page.

Guidelines and rules

Privacy

The Central File Storage Service is provided to support UW activities and is subject to state laws and UW policy.

• Use caution when storing sensitive information. This includes personnel data, patient records, student information, and financial information. For more information, see the General Rules for Collection, Use, and Disclosure of Institutional Information.

Data as Public Record

Data is a public record when it is created or stored in the transaction of public business. As such, it must be retained as evidence in accordance with UW records retention practices:

• UW Records Management – Information records management, retention, storage, and destruction
• RCW 40.14 – Washington State law relating to preservation and destruction of public records

Information for departmental IT Staff

Benefits of the U Drive

• User self-service file recovery via snapshots
• UW-IT service with 24/7 monitoring and helpdesk support provided by help@u
• Reduces the storage capacity requirements for individual units
• Single Sign On (SSO) enables access without a password prompt when logged on with NetID credentials

Windows Drive Mounting

U Drive share can be mounted as a traditional Windows network drive by users, via a logon script, or via GPO.

For users logged onto computer with their UW NetID credentials their credentials are passed through automatically. Units can enable UW NetID logins via either:

Below is the syntax for a simple .BAT script that is executed on user logon:

NET USE U: udrive.uw.eduudrive /PERSISTENT:YES

If a user is not logged on with their NETID credentials, then they need to specify their NETID username:

NET USE U: udrive.uw.eduudrive /USER:NETID%username% /PERSISTENT:YES

While any letter maybe used, departments are encouraged to use “U:” if feasible to provide a standard mount point across campus.

Windows “homeDirectory” Support for NETID Users

This information is for units who have a UW-IT Computer Support Org set up.

The AD attributes for “homeDrive” and “homeDirectory” can be set via the support group tool under the NETID Domain Settings section.

This will cause Windows to automatically map the U Drive upon login. Programs that use the user variables %HOMEDRIVE% and %HOMESHARE% will be able to make use of the U Drive automatically.

Mac and Linux Single Sign On Support

SSO support for Mac and Linux users is provided via the Kerberos tickets. Users can obtain a Kerberos ticket by authenticating via the NETID.WASHINGTON.EDU realm, or by requesting a ticket via the kinit command:

kinit netid@NETID.WASHINGTON.EDU

Subsequent mounts of smb://udrive.uw.edu/udrive should complete without a username/password prompt.

Uwb-dfu Driver

Additionally Macs and Linux machines joined to a UW NetID delegated OU support SSO for users logged on via NetID credentials.
