------------------------------------------------------------------------------- flashrom README ------------------------------------------------------------------------------- flashrom is a utility for detecting, reading, writing, verifying and erasing flash chips. It is often used to flash BIOS/EFI/coreboot/firmware images in-system using a supported mainboard, but it also supports flashing of network cards (NICs), SATA controller cards, and other external devices which can program flash chips. It supports a wide range of DIP32, PLCC32, DIP8, SO8/SOIC8, TSOP32, and TSOP40 chips, which use various protocols such as LPC, FWH, parallel flash, or SPI. Do not use flashrom on laptops! The embedded controller (EC) present in many laptops interacts badly with any flash attempts and can brick your laptop permanently. Please make a backup of your flash chip before writing to it. Please see the flashrom(8) manpage. Packaging --------- To package flashrom and remove dependencies on subversion, either use make export or make tarball make export will export all flashrom files from the subversion repository at revision BASE into a directory named $EXPORTDIR/flashrom-$VERSION-r$SVNREVISION and will additionally modify the Makefile in that directory to contain the svn revision of the exported tree. make tarball will simply tar up the result of make export and gzip compress it. The snapshot tarballs are the result of make tarball and require no further processing. Build Instructions ------------------ To build flashrom you need to install the following software: * pciutils+libpci (if you want support for mainboard or PCI device flashing) * libusb (if you want FT2232, Dediprog or USB-Blaster support) * libftdi (if you want FT2232 or USB-Blaster support) Linux et al: * pciutils / libpci * pciutils-devel / pciutils-dev / libpci-dev * zlib-devel / zlib1g-dev (needed if libpci was compiled with libz support) On FreeBSD, you need the following ports: * devel/gmake * devel/libpci On OpenBSD, you need the following ports: * devel/gmake * sysutils/pciutils To compile on Linux, use: make To compile on FreeBSD, OpenBSD or DragonFly BSD, use: gmake To compile on Nexenta, use: make To compile on Solaris, use: gmake LDFLAGS="-L$pathtolibpci" CC="gcc -I$pathtopciheaders" CFLAGS=-O2 To compile on NetBSD (with pciutils, libftdi, libusb installed in /usr/pkg/), use: gmake To compile and run on Darwin/Mac OS X: Install DirectHW from coresystems GmbH. DirectHW is available at http://www.coreboot.org/DirectHW . To cross-compile on Linux for DOS: Get packages of the DJGPP cross compiler and install them: djgpp-filesystem djgpp-gcc djgpp-cpp djgpp-runtime djgpp-binutils As an alternative, the DJGPP web site offers packages for download as well: djcross-binutils-2.19.1-10ap.i386.rpm djcross-gcc-4.3.2-8ap.i686.rpm djcrx-2.04pre_20090725-13ap.i386.rpm The cross toolchain packages for your distribution may have slightly different names (look for packages named *djgpp*). You will need the following library source trees containing their compiled static libraries either in the parent directory of the flashrom source or specify the base folder on compile time with the LIBS_BASE parameter. The default as described above is equal to calling 'make djgpp-dos LIBS_BASE=..' To get and build said libraries... Download pciutils 3.1.5 and apply http://flashrom.org/File:Pciutils.patch.gz Compile pciutils, see README.DJGPP for instructions. Download and compile http://flashrom.org/File:Libgetopt.tar.gz Enter the flashrom directory. Run either (change settings where appropriate) make CC=i586-pc-msdosdjgpp-gcc STRIP=i586-pc-msdosdjgpp-strip or (above settings hardcoded) make djgpp-dos To run flashrom.exe, download http://flashrom.org/File:Csdpmi7b.zip and unpack CWSDPMI.EXE into the current directory or one in PATH. To cross-compile on Linux for Windows: Get packages of the MinGW cross compiler and install them: mingw32-filesystem mingw32-cross-cpp mingw32-cross-binutils mingw32-cross-gcc mingw32-runtime mingw32-headers The cross toolchain packages for your distribution may have slightly different names (look for packages named *mingw*). PCI-based programmers (internal etc.) are not supported on Windows. Run (change CC= and STRIP= settings where appropriate) make CC=i686-w64-mingw32-gcc STRIP=i686-w64-mingw32-strip Processor architecture dependent features: On non-x86 architectures a few programmers don't work (yet) because they use port-based I/O which is not directly available on non-x86. Those programmers will be disabled automatically if you run "make". Installation ------------ In order to install flashrom and the manpage into /usr/local, type: make install For installation in a different directory use DESTDIR, e.g. like this: make DESTDIR=/usr install If you have insufficient permissions for the destination directory, use sudo by adding sudo in front of the commands above.
