Overview

Extract and dump Intel Firmware Descriptor information.

Options

-d | --dump: dump intel firmware descriptor

-f | --layout <filename>: dump regions into a flashrom layout file

-F | --fmap-layout <filename>: dump IFD regions into a fmap layout template (.fmd) file

-t | --validate: Validate that the firmware descriptor layout matches the fmap layout

-C | --chip <0|1|2>: select spi chip on which to operate can only be used once per run:

0 - both chips (default) 1 - first chip 2 - second chip

-e | --em100: set SPI frequency to 20MHz and disable Dual Output Fast Read Support
