TheUSB7206 supports legacy Type-B connectivity on the upstream port and Type-A connectivity on thedownstream ports. The hub downstream configuration includes 5 x USB 3.2 Gen 2 ports and an additional USB2.0 port. TheUSB7206 also supports the legacy USB speeds (HS/FS/LS) through a dedicated USB2.0 hub controller that is the culmination of six generations of Microchip hubfeature controller design and experience with proven reliability,interoperability, and device compatibility. The SuperSpeed Plus hub controlleroperates in parallel with the USB 2.0 controller, decoupling the 10 Gbps SSdata transfers from bottlenecks due to the slower USB 2.0 traffic.

Use outside of the ambient conditions could cause the device to fail and/or function incorrectly. These ambient conditions are applicable for the environment immediately around the device under all operational conditions. When used with an external enclosure, active temperature control and/or other cooling solutions are recommended to ensure the device is maintained within these ranges. The device design features a cooling channel in between the front section and rear sleeve. When you implement the device, make sure this cooling channel is not obstructed.
The IC has an I2C master that can read and write to other devices in the system so that its firmware can configure related devices without the main processor's assistance. For example, it can configure an external charger based on BC1.2 detection, CC detection, and PD communication.
The Synopsys IP Prototyping Kits for USB 3.1 Host and Device center around complete, out-of-the-box reference designs that consist of a validated IP configuration and necessary SoC integration logic. IP Prototyping Kits are available as soft deliverables requiring various hardware prerequisites such as a HAPS system, cables, and other accessories. All IP kits include reference drivers, SoC integration logic, and application examples.

Nevertheless I think that Cypress should have made an app in Linux to load the firmware into target FX3, otherwise they have always to go windows...There is an application note declared obsolete ? -notes-obsolete/an73609-ez-usb-fx2lp-fx3-developing-bulk-loop-example-linuxOscar More All Messages By This Member

08_cybulk.cpp (This program is a CLI program that does a bulk transfer using the bulkloop.hex file downloaded to the FX2 device)
09_cyusb_performance.cpp (This is a CLI program which can be used to measure the data transfer rate for data (IN or OUT endpoint) transfers from a Cypress USB device. Endpoints of type Bulk, Interrupt and Isochronous are supported)
download_fx3.cpp (Downloads FX3 firmware to RAM, I2C EEPROM or SPI Flash)
It is getting late here, but tomorrow night or over the weekend when I have more time, I plan to try to build them to see if they have any problems compiling.Franco More All Messages By This Member

this morning I also spent some time to get the FX3 firmware from BBRF103_SRC to compile on my Linux box (with just command line commands) using the latest EZ-USB FX3 SDK (1.3.4) and the latest GNU Arm toolchain (9-2020-q2); I had to make a few changes here and there, and I just pushed the updated code on GitHub ( ) - this code worked for me to compile and build the firmware
I also put the detailed instructions in the README file ( _SRC/README.md) for those who want to give it a try and play around building their own firmware
I noticed a couple of things during the build of the firmware:the linker/loader had this warning (I am not really sure if it is important or not): arm-none-eabi-ld: sdrx3.elf: warning: sh_link not set for section `.ARM.exidx'
elf2img also had this message (again I am not sure if it is a big deal or not): Note: 256 bytes of interrupt vector code have been removed from the image. Use the "-vectorload yes" option to retain this code.
finally I compared the generated firmware image with the ones for the RX-666 (RX666.img) and RX888 (rx888.img), and I noticed something interesting - in your firmware you have the thread ID and thread name set to '21:Bulk_src_sink' (same as the Cypress SDK example), while both RX666.img and rx888.img have it set to '21:BBFR103_fifo_sync' (note the identical misspelling of BBRF103 into BBFR103); which makes me think they probably share a common origin - I did some quick search on GitHub, but I couldn't find that string (I didn't spend much time on it, so I might have missed something obvious).

HubToolis an example application utilizing the Qt GUI framework. Source code for HubTool is available in theDownload Center, which can serve as a quick start to writing your own GUI application to meet your needs. It also serves as a good entry tool for understanding the functionality of the USBHub3+, or just watching the battery charge curves of your various devices.
USB today provides a fast, bi-directional, low-cost, serial interface that offers easy connectivity to PCs. A hallmark for USB operation has been the ability for the host to automatically recognize devices as they are attached and install the appropriate drivers. With features such as backward compatibility with previous devices and hot "plug-ability", USB has become the de-facto standard interface for various consumer and PC peripheral devices. The USB standard allows up to 127 devices connected to a Host System. USB designates low, full, high-speed connectivity between devices compatible with the 2.0 specification. Most full speed devices include lower bandwidth mice, keyboards, printers, and joysticks. The use of high speed USB has exploded with the rapid growth in digital media in the consumer electronics market including media players, digital cameras, external storage and smart phones.
SuperSpeed USB is designator for links operating at the 5 GHz frequency and compatible with the USB 3.0 specification. SuperSpeed USB provides a high performance connection topology for applications that utilize larger files or require higher bandwidth. SuperSpeed USB is backward compatible with USB 2.0, resulting in a seamless transition process for the end user. SuperSpeed USB offers a compelling opportunity for digital imaging and media device vendors to migrate their designs to higher performance USB 3.0 capable interface.
As evidenced by USB popularity, several extensions of the technology have been introduced to try and capitalize on its installed base/ popularity. An example of this extension, which is supported and approved by the USB Implementers Forum (USB-IF), is USB On-The-Go (OTG). Designed to allow portable computing devices, such as cell phones and digital cameras, the ability to connect to other USB devices as either a host or peripheral, OTG promises improved interoperability for an enormous number of USB enabled devices.
The role of the host controller (plus software) is to provide a uniform view of IO systems for all applications software. For the USB IO subsystem in particular, the host manages the dynamic attach and detach of peripherals. It automatically performs the enumeration stage of device initialization which involves communicating with the peripheral to discover the identity of a device driver that it should load, if not already loaded. It also provides device descriptor information that drivers can use enable specific features on the device. Peripherals add functionality to the host system or may be standalone embedded operation. When operating as a USB device, peripherals act are slaves that obey a defined protocol. They must react to requests sent from the host. It's largely the role of PC software to manage device power without user interaction to minimize overall power consumption. The USB 3.0 specification redefines power management to occur at the hardware level with multiple power states designed to reduce power usage across the IO system. 2ff7e9595c
