Hacking the FPGA bitstream

Squok writes referring us to several documents he’s found regarding hacking the bitstream in secure FPGAs: In order to protect the intellectual property and to prevent fraud, e.g., by cloning an FPGA or manipulating its content, many current FPGAs employ a bitstream encryption feature, which is advertised by manufacturers as “making it virtually impossible for […]

Logic Sniffer test release 2.11

The Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. This project is a collaboration between the Gadget Factory and Dangerous Prototypes. Jack posted Logic Sniffer bitstream test release 2.11 with bigger samples and RLE improvements: Extends memory depths from 8k and […]

Logic Sniffer upgrade v2.1 released

Package v2.1 is the first official upgrade release for the Logic Sniffer. Download it now at the Gadget Factory. This version has a lot of updates that should fix a bunch of problems in the initial release: FPGA bitstream v2.1 with high-speed SPI connection between the PIC and FPGA. This eliminates most ‘hardware not found’ […]

Logic Sniffer upgrade procedure

This is an old version, see the latest version on the documentation wiki. The Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. This project is a collaboration between the Gadget Factory and Dangerous Prototypes. The Logic Sniffer has two parts that […]

Logic Sniffer FPGA bitstream/ROM update

This is an old version, see the latest version on the documentation wiki. The Logic Sniffer stores the FPGA (IC3) bitstream in a flash ROM chip (IC2). The PIC microcontroller (IC1) can update the bitstream from a computer using the multi-platform pump-loader application. This feature lets us release FPGA design updates with new features and […]
