Configure SPI flash write protection.

SPIblock

SPIblock is a proof of concept tool that allows programming on-flash write protection. It supports most common SPI flash chips, which are identified using flashrom's database.

Requirements

SPIblock requires:

• Python 3.2 or higher
• pyBusPirateLite library
• Bus Pirate v3.6 or v4

Usage

usage: spiblock.py [-h] [-u USPEED] [-x SPEED] [-d DEV] [-t TIMEOUT] [-v] [-f]
               [-p] [-s] [-b BP] [-w WP] [--version]

SPIblock

optional arguments:
  -h, --help            show this help message and exit
  -u USPEED, --uspeed USPEED
                        Set UART speed
  -x SPEED, --speed SPEED
                        Set SPI speed
  -d DEV, --dev DEV     Set Bus Pirate device path
  -t TIMEOUT, --timeout TIMEOUT
                        Set SPI timeout in seconds
  -v, --verbose         Enable verbose output
  -f, --force           Assume SPI device supports generic write protection
  -p, --probe           Probe for SPI device
  -s, --status          Get SPI device status
  -b BP, --bp-state BP  Enable (1) or disable (0) block protection
  -w WP, --wp-state WP  Enable (1) or disable (0) WP pin control
  --version             show program's version number and exit
