To query the FW image on a device, use the following command line:
# flint -d <device> q
To query the FW image in a file, use the following command line:
# flint -i <image file> q
where:
|
device |
Device on which the query is run. |
|
image file |
Image file on which the query is run. |
Examples:
-
Query the FW on the device.
# flint -d /dev/mst/mt4133_pciconf0 query
-
Query the FW image file.
# flint -i 25408-2_42_5000-MCX354A-FCB_A2.bin query
-
Security Attributes field in Query output:
This field lists the security attributes of the device’s firmware, where:-
Secure-fw: This attribute indicates that this binary/device supports secure-firmware-updates. It means that only officially signed binaries can be loaded to the device from the host, and that the current binary is signed.
-
Signed-fw: This attribute indicates that that this binary is signed and that the device can verify digital signatures of new updates. However, unlike, secure-fw, there might still be methods to upload unsigned binaries to the device from the host.
-
debug: This attribute indicate that this binary is (or this device runs) a debug-version. Debug versions are custom made for specific data-centers or labs, and can only be installed after a corresponding debug-fw token is pushed to the device. The debug-fw-token, which is digitally signed, includes a list of the target devices MAC addresses.
-
dev: This attribute indicates that the firmware is signed with development (test) key.
-
-
Default Update Method" field in Query Full output:{This field reflect the method which flint will use in order to update the device. The user can enforce a different method using the --no_fw_ctrl or the --ocr flags.The default methods are:
-
Legacy: flint will use the low level flash access registers.
-
fw_ctrl: flint will operate the ‘firmware component update’ state machine.
-
-
Secure-boot attributes
-
Secure-boot : This attribute indicates if the device supports secure-boot
-
Life-cycle : This attribute indicates the current status of secure-boot
-
Security-version:For query on image: This attribute indicates the security-version of the image. For query on device:“EFUSE security version”: Indicates the security version of the device“Image security version”: Indicates the security version of the image on the flashProgramming method: Indicates when the boot will program the “EFUSE security version” to be aligned with the “image security version”.
