Project status• Implementation done• Hardware part
– TI TUSB 9261 EVM board device– SATA SSD for testing– PC host with necessary software for compiling and testing
• Software part– TUSB926x flash burner utility– TI confidential source code for TUSB9261 firmware– Code Compiler Studio (TI official C/C++ compiler)

• Implementation to be done
To redevelop the firmware source code, redesign the SCSI command handler, correctly block writing commands without fault. Testing and evaluation comes together with code development.

Testing to be done• TI TUSB 9261 Evaluation Board• Intel® Core™2 Duo processor E8000: The processor is
efficient in that it reduces the amount of power need by the CPU therefore less CPU heat and prolonged system’s life.
• Hard Disk: Intel SSD 320 Series 80GB• Excellent performance and energy efficiency: The device
high performance and is power efficient. The device needs testing in superSpeed USB mode.
• The bridge has support for data rate of up to 5Gbps. • The device drops writing commands and allows reading
commands. In this case the no data is contaminated by modification of information contained in the external HDD.

Success criteria and assessment
• The project succeeds when code implementation is done and passes all tests
• To what degree the team would attain success– Mostly confident
