The wiki is being retired!

Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to Contributions welcome!

ectool is a small utility that dumps the RAM of a laptop's Embedded/Environmental Controller (EC).

It expects an EC as described in the ACPI specification. Only ACPI-compliant ECs will be detected.


Manual installation

$ git clone
$ cd coreboot/util/ectool
$ make
$ sudo make install

You can browse the ectool source code using the web interface.


$ ectool

Please see ectool -h for information on various other options.
