DESCRIPTION

    flint is a FW (firmware) burning and flash memory operations tool for Mellanox Infiniband HCAs,Ethernet NIC cards, and switch devices.

OPTIONS

-d|--device <device>
    Device flash is connected to. Commands affected: all

-i|--image <image>
    Binary image file. Commands affected: burn, verify

--latest_fw
    : Commands affected: burn

--ir
    : Commands affected: burn

-h|--help
    Prints this message and exits

--hh
    Prints extended command help

-y|--yes
    Non interactive mode - assume answer "yes" to all questions. Commands affected: all

--no
    Non interactive mode - assume answer "no" to all questions. Commands affected: all

--guid <GUID>
    GUID base value. 4 GUIDs are automatically assigned to the following values:

guid
    -> node GUID

guid+1 -> port1
    guid+2 -> port2 guid+3 -> system image GUID.

Note: port2 guid will be assigned even for a
    single port HCA - The HCA ignores this value.

    Commands affected: burn, sg

--guids <GUIDS...>
    4 GUIDs must be specified here. The specified GUIDs are assigned to the following fields, respectively: node, port1, port2 and system image GUID.

Note: port2 guid must be specified even for
    a single port HCA - The HCA ignores this value. It can be set to 0x0.

    Commands affected: burn, sg

--mac <MAC>
    MAC address base value. 2 MACs are automatically assigned to the following values:

mac -> port1

mac+1
    -> port2

    Commands affected: burn, sg

--macs <MACs...>
    2 MACs must be specified here. The specified MACs are assigned to port1, port2, respectively. Commands affected: burn, sg

Note: -mac/-macs flags are applicable only
    for Mellanox

    Technologies ethernet products.

--uid <UID>
    ConnectIB/SwitchIB only. Derive and set the device UIDs (GUIDs, MACs, WWNs). UIDs are derived from the given base UID according to Mellanox Methodology Commands affected: burn, sg

--blank_guids
    Burn the image with blank GUIDs and MACs (where applicable). These values can be set later using the "sg" command (see details below).

    Commands affected: burn

--clear_semaphore
    Force clear the flash semaphore on the device. No command is allowed when this flag is used. NOTE: May result in system instability or flash corruption if the device or another application is currently using the flash. Exercise caution.

--qq
    Run a quick query. When specified, flint will not perform full image integrity checks during the query operation. This may shorten execution time when running over slow interfaces (e.g., I2C, MTUSB-1). Commands affected: query

--low_cpu
    : When specified, cpu usage will be reduced. Run time might be increased Commands affected: query

--flashed_version
    : When specified, only flashed fw version is fetched Commands affected: query

--nofs
    Burn image in a non failsafe manner.

--allow_rom_change
    Allow burning/removing a ROM to/from FW image when product version is present. Use only if you know what you are doing

--override_cache_replacement
    On SwitchX/ConnectIB devices: Allow accessing the flash even if the cache replacement mode is enabled. NOTE: This flag is intended for advanced users only. Running in this mode may cause the firmware to hang.

--no_flash_verify
    Do not verify each write on the flash.

--use_fw
    Flash access will be done using FW (ConnectX-3/ConnectX-3Pro only).

-s|--silent
    Do not print burn progress flyer. Commands affected: burn

--vsd <string>
    Write this string, of up to 208 characters, to VSD when burn.

--use_image_ps
    Burn vsd as appears in the given image - do not keep existing VSD on flash. Commands affected: burn

--use_image_guids
    Burn (guids/macs) as appears in the given image. Commands affected: burn

--use_image_rom
    Do not save the ROM which exists in the device. Commands affected: burn

--use_dev_rom
    Save the ROM which exists in the device. Commands affected: burn

--ignore_dev_data
    Do not attempt to take device data sections from device(sections will be taken from the image. FS3 Only). Commands affected: burn

--no_fw_ctrl
    Do not attempt to work with the FW Ctrl update commands

--dual_image
    Make the burn process burn two images on flash (previously default algorithm). Current default failsafe burn process burns a single image (in alternating locations). Commands affected: burn

--striped_image
    Use this flag to indicate that the given image file is in a "striped image" format. Commands affected: query verify

--banks <bank>
    Set the number of attached flash devices (banks)

--log <log_file>
    Print the burning status to the specified log file

--flash_params <type, log2size,

num_of_flashes>
    Use the given parameters to access the flash

instead of reading them from the flash.
    Supported parameters: Type: The type of the flash, such as:M25PXxx, M25Pxx, N25Q0XX, SST25VFxx, W25QxxBV, W25Xxx, W25Qxxx, W25Qxxx, AT25DFxxx, S25FLXXXP, S25FL11xx, MX25L16xxx, MX25Lxxx, S25FLxxx, IS25LPxxx. log2size: The log2 of the flash size.num_of_flashes: the number of the flashes connected to the device.

-v|--version
    Version info.

--private_key <key_file>
    path to PEM formatted private key to be used by the sign command

--key_uuid <uuid_file>
    UUID matching the given private key to be used by the sign command
