The Lattice Sentry Demo Board for Mach-NX help you develop and test a NIST SP 800-193-compliant PFR solution on a single board, using the Mach-NX as a Platform Root of Trust, and two Lattice ECP5 FPGAs which act as PFR-protected ICs in the system.
The Lattice Sentry Demo Board for Mach-NX Devices has two FTDI chips (FT2232H) to communicate with the various FPGAs on the board over JTAG and UART. When programming the FPGAs, only the FTDI chip marked U1 (connected to USB port J1) should be connected. Make sure that no other FTDI chips are connected by USB to the computer performing the programming.
Protect – Using the Lattice Sentry Root of Trust Solution for Mach-NX, developers can test authentication of the protected ICs’ firmware using 384-bit key strength, before they boot.
Detect – The platform detects and blocks illegal SPI and SPI flash operations. This can be controlled and monitored using a dedicated user interface on a PC workstation.
Recover – The design can automatically replace damaged boot images of the Mach-NX and protected external devices with known good versions.
