Kit Overview

The Texas Instruments TUSB9261DEMOTUSB9261DEMO board is a free-standing reference design that acts as a bridge between a SuperSpeed USB (USB 3.0) bus and a Serial–ATA (SATA) device. The TUSB9261DEMOTUSB9261DEMO is used to evaluate system compatibility. It provides a TUSB9261 hardware reference design for connection to a SATA device such as a solid state drive, hard disk drive, DVD drive, or Blu-Ray drive. The included firmware is capable of supporting a single SATA drive and supports the following:

USB Attached SCSI (UAS)
USB Mass Storage Class (MSC) Bulk-Only Transport (BOT) including the 13 error cases.
USB Mass Storage Specification for Bootability
USB Device Class Definition for Human Interface Devices (HID) for firmware update and manufacturer-specific custom functionality
Serial ATA Advanced Host Controller Interface (AHCI)
General Purpose Input/Output (GPIO)
Pulse Width Modulation (PWM) for LED dimming control
Serial Peripheral Interface (SPI) for updating firmware and loading custom device descriptors
Serial Communications Interface (SCI) for debug output only

The board works with the LINUX, MAC, and Windows native Mass Storage Class Drivers.

The TUSB9261DEMOTUSB9261DEMO board as supplied is intended to operate as a USB bus-powered peripheral with solid-state-drives. In order to use the DEMO board with higher current devices such as hard drives or optical drives, an external power supply is required.

The TUSB9261 is an ARM cortex M3 microcontroller based USB 3.0 to serial ATA bridge. It provides the necessary hardware and firmware to implement a USB attached SCSI protocol (UASP) compliant mass storage device suitable for bridging hard disk drives (HDD), solid state disk drives (SSD), optical drives and other compatible SATA 1.5-Gbps or SATA 3.0-Gbps devices to a USB 3.0 bus. In addition to UASP support, the firmware implements the mass storage class bulk-only transport (BOT), and USB human interface device (HID) interfaces.

Key Applications: External HDD/SSD, External DVD, External CD, HDD-Based Portable Media Player

TUSB9261 Demo Board

Unfortunately, TI doesn't allow 3rd party development for the TUSB926x series (no programmer's reference manual, no register map, nothing...).

So... yeah. A nice but rather useless board.
