NAME
dfu-suffix - add, check, or remove DFU firmware file suffix
SYNOPSIS
dfu-suffix [options] --add DFU_FILE
dfu-suffix --check DFU_FILE
dfu-suffix --delete DFU_FILE
dfu-suffix --help
dfu-suffix --version
DESCRIPTION
The program dfu-suffix can be used to add, check or remove a DFU firmware file suffix, recommended for safely matching a firmware file and device.
Note that a suffix is recommended by the DFU standard, but not required. A DFU host tool like dfu-util will recognize the suffix and use it to check that the device is matching, but not transfer the suffix to the device.

- -p, --pid productID
-

EXAMPLES
- dfu-suffix --vid 0123 --add firmware.dfu
-
Adds a suffix matching vendor 0x0123 and product ID 0x4567. Since product and device ID are not specified, they will contain the wildcard value 0xFFFF.
- dfu-suffix --check firmware.dfu
-
Checks the file firmware.dfu for a valid DFU suffix
- dfu-suffix --delete firmware.dfu
-
Removes a valid DFU suffix from the file firmware.dfu
EXIT VALUES
- 0
-
Success (also if suffix is missing)
- -64
-
Usage error
LIMITATIONS
dfu-suffix can not tell a broken DFU suffix (e.g. checksum mismatch) from a non-existing suffix, so only a valid suffix can be removed.
