Chrome OS Scripts

These scripts can be used to access or generate Chrome OS resources, for example to extract System Agent reference code and other blobs (e.g. mrc.bin, refcode, VGA option roms) from a Chrome OS recovery image.

crosfirmware.sh

crosfirmware.sh downloads a Chrome OS 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 Chrome OS firmware images, run

$ ./crosfirmware.sh

To download, e.g. the Panther firmware image, run

$ ./crosfirmware.sh panther

extract_blobs.sh

extract_blobs.sh extracts the blobs from a Chrome OS firmware image.

Right now it will produce the ME firmware blob, IFD, VGA option rom, and mrc.bin.

gen_test_hwid.sh

gen_test_hwid.sh generates a test-only identifier in Chrome OS HWID v2 compatible format.

Usage:

$ ./gen_test_hwid.sh BOARD_NAME

Example:

$ ./gen_test_hwid.sh Kukui
KUKUI TEST 9847
