From 9a4881a783fa1edc730dc484bb2c293d92e45823 Mon Sep 17 00:00:00 2001 From: Joe Pillow Date: Fri, 19 Feb 2016 15:18:14 -0800 Subject: util: Add scripts to download and extract blobs This turned out really handy when I tried to build coreboot for my Chromebox. These scripts can be used 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 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 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 Change-Id: I5fb7e14b10e03e18cd360bc35f1dc92e8ed34e63 Signed-off-by: Joe Pillow Reviewed-on: https://review.coreboot.org/13752 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth --- util/chromeos/README.md | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 util/chromeos/README.md (limited to 'util/chromeos/README.md') diff --git a/util/chromeos/README.md b/util/chromeos/README.md new file mode 100644 index 0000000000..3c3d721a3c --- /dev/null +++ b/util/chromeos/README.md @@ -0,0 +1,27 @@ +Chrome OS binary extraction +=========================== + +These scripts can be used 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 -- cgit v1.2.3
