This guide covers how to use cros ap
tooling. If you're interested in changing/fixing config for your board, please refer to ap_firmware_config/README.md
To build the AP Firmware for board foo
:
cros ap build -b foo
To build the AP Firmware only for foo-variant
:
cros ap build -b foo --fw-name foo-variant
Flashing via servo requires servod process to be running.
To flash a DUT with an IP of 1.1.1.1 via SSH:
cros ap flash -b $BOARD -i /path/to/image.bin -d ssh://1.1.1.1
To flash a DUT via SERVO on the default port (9999):
cros ap flash -d servo:port -b $BOARD -i /path/to/image.bin
To flash a DUT via SERVO on port 1234:
cros ap flash -d servo:port:1234 -b $BOARD -i /path/to/image.bin
To pass additional options to futility or flashrom, provide them after --
, e.g.:
cros ap flash -b $BOARD -i /path/to/image.bin -d ssh://1.1.1.1 -- --force
To read firmware image of a DUT with an IP of 1.1.1.1 via SSH:
cros ap read -b $BOARD -o /tmp/read-image.bin -d ssh://1.1.1.1
If you don't have ssh access from within the chroot, you may set up ssh tunnel:
ssh -L 2222:localhost:22 1.1.1.1 cros ap read -b $BOARD -o /tmp/read-image.bin -d ssh://localhost:2222
To read image from DUT via SERVO on port 1234:
cros ap read -b $BOARD -o /tmp/read-image.bin -d servo:port:1234
To read a specific region from DUT via SERVO on default port(9999):
cros ap read -b $BOARD -r region -o /tmp/read-image.bin -d servo:port
To dump AP config of all boards to stdout
cros ap dump-config
To dump AP config of all boards into /tmp/cros-read-ap-config.json
cros ap dump-config -o /tmp/cros-read-ap-config.json
To dump AP config of drallion and dedede boards:
cros ap dump-config -o /tmp/cros-read-ap-config.json -b "drallion dedede"
To unmerge firmware-related packages and clear /build/$BOARD/firmware
directory:
cros ap clean -b $BOARD
