2. Project goal Implement a USB to SATA device write blocker
A device with both USB 2.0 and USB 3.0 enabled
A device working as a USB to SATA adapter with writing block enabled

4. Block diagram

5. Project status Implementation done Hardware part Software 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)

6. 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.

7. 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.

8. 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
