Alereon Wireless USB Host DFU Driver



Tell me to enter the STM Device in DFU Mode driver. DFU or DfuSe is the USB package for do a firmware upgrade on STM32 via USB. The Raspberry Pi 3 only supports USB host mode, and the STM32F103 only device mode. In order to flash those boards one needs a special tool that talks to the DFU bootloader using special USB commands. The ultimate vision of Alereon is to have a peripheral device integrated into a wireless dongle of types so that no drivers or software is needed to install on the host computer, it would simply be plug-n-play. Don’t you wonder what the iPhone will be like in 3 years? Alereon press release. I don't get the 'Unknown device' (look at DFU-Driver-Re-install.JPG in previous topic), device is marked as CSR-Bluecore in DFU mode! I looks nearly impossible to me that CSR would 'allow/bring' a feature (DFU update over USB), and that this would not work!

Jun 05, 2009 (AsiaPulse via COMTEX) -- (Full text of a statement. Contact details below.) (BW)(TX-ALEREON) Alereon to Showcase iPhone Wireless USB Peripheral at COMPUTEX TAIPEI 2009 First Peripheral to Showcase High Throughput Connectivity for the iPhone and iPod Consumer Tradeshow Writers/Technology Editors COMPUTEX TAIPEI 2009 AUSTIN, Texas--(BUSINESS WIRE) - Jun. 01, 2009-- Alereon, Inc., the Certified Wireless USB technology leader for Worldwide Ultra Wideband (UWB) WiMedia solutions, today announced the first demonstration of an Apple iPhone/iPod peripheral reference design based on the new worldwide, low power 90nm-LP AL5301 chip built at Samsung's 12inch wafer fabrication facility in Korea.


The demonstration consists of a small wireless USB peripheral connected to a typical iPhone or iPod's edge connector. The adapter enables any iPhone or iPod to both provide extra battery power/charging as well as synchronize wirelessly to iTunes whether on a Windows or MAC OS machine.
Future enhancements will enable connectivity to HDTVs for displaying photos or videos.
'The success of the Apple iPhone and iPod motivated us to apply the simplicity of our low power Wireless USB solution to the needs for high throughput wireless connectivity for synchronization,' said Eric Broockman, CEO at Alereon. 'Our new AL5301, because of its low power consumption, allowed us to produce a small form factor ideal for use with Apple's elegant iPhone family.' In addition to reducing the size and power consumption of wireless USB hardware, Alereon is also now delivering a next generation of software that provides increased throughput together with a simpler user installation experience. This includes a new Driverless USB dongle which simplifies the installation process by not requiring any drivers to be installed on the PC. Simply plug in the dongle and it is ready to connect straight out of the box. Alereon has also increased wireless USB performance, providing over 130Mbps of delivered throughput for native mass storage applications, over 175Mbps for video applications over Wireless USB and over 200Mbps of throughput for future DLNA based applications.
The AL5301 is pin for pin compatible with the prior AL5300 which enables OEMs to easily transition existing products to this device to capitalize on the AL5301's lower power consumption and enhanced feature set.

One of the great things about software, compared with hardware, is the ease with which it may be changed and updated. The big downside of software is also the ease with which it can be changed. This ease can make software developers lazy, as they know that they can always fix things later. This is a sharp contrast to chip developers who are fearful of errors, as an ASIC respin is both time consuming and very expensive.

On a desktop computer, updates to system and application software seem to come thick and fast, giving vendors the opportunity to provide us with new features, fix old bugs and introduce new and interesting ones. For embedded systems, the matter is a little more complex …

Alereon Wireless Usb Host Dfu Driver Windows 7

Years ago, embedded system software [firmware] was burned into a PROM and inserted into a socket in the target system. Later changes to software simply involved the swapping of PROMs. I say “simply”, but it could be far from simple, as several pitfalls were possible:

  • Getting the right PROMs in the right sockets [the right way around].
  • Finding PROMs had been soldered on to the board to cut costs.
  • The system has shipped to numerous customers …

Nowadays, matters are generally eased because the majority of embedded systems keep their code in flash memory, which can normally be reprogrammed in situ. There are broadly 3 ways that the updated code might be transferred to the device:

  • Network
  • Wireless
  • USB

If the embedded device is connected to the Internet or even just to a LAN, there are a selection of possible ways to implement software updates. This is somewhat similar to the situation with desktop computers.

Wireless connectivity gives other options. If it is a network connection, the same opportunities are available as with a wired network. But there are also other possibilities. A set top box or video recorder might receive updates via TV transmissions. A spacecraft [on the surface of Mars, for example] might receive updates via the NASA Deep Space Network.

Alereon Wireless Usb Host Dfu Driver Updater

For those of us still on planet Earth, a common connectivity option is USB, topic that I have written on before. There is a USB device class called Device Firmware Upgrade [DFU], which defines a protocol for sending new firmware to a device.

The specification for DFU is freely and readily available and support is available in many embedded USB stacks – including Nucleus USB, of course.

The details of DFU operation are well documented and quite complex, but the basic principle is quite straightforward. If a device supports DFU, it advises the host of this fact during enumeration. The device then operates in two distinct modes: “normal” mode and DFU mode. When the device is connected to the host, it appears to be a normal peripheral. For example, a keyboard would appear to be a normal HID class device and be connected to the appropriate host driver. When the device enters DFU mode, it disconnects from the host, then reconnects as a DFU device and is associated with the host DFU driver, which manages the update transfer.

A small downside of DFU is that no standard Windows driver is provided. However, drivers are available from other sources.
