These scripts can be used to access or generate ChromeOS resources, for example to extract System Agent reference code and other blobs (e.g. mrc.bin, refcode, VGA option roms) from a ChromeOS recovery image.
crosfirmware.sh downloads a ChromeOS recovery image from the recovery image server, unpacks it, extracts the firmware update shell archive, extracts the firmware images from the shell archive.
To download all ChromeOS firmware images, run
$ ./crosfirmware.sh
To download, e.g. the Panther firmware image, run
$ ./crosfirmware.sh panther
extract_blobs.sh extracts the blobs from a ChromeOS firmware image.
Right now it will produce the ME firmware blob, IFD, VGA option rom, and mrc.bin.
gen_test_hwid.sh generates a test-only identifier in ChromeOS HWID v2 compatible format.
Usage:
$ ./gen_test_hwid.sh BOARD_NAME
Example:
$ ./gen_test_hwid.sh Kukui KUKUI TEST 9847
