NAME

6       dfu-prefix - add, check, or remove special firmware file prefix
7

SYNOPSIS

9       dfu-prefix [ -s address | -L ] --add DFU_FILE
10       dfu-prefix [ -T | -L ] --check DFU_FILE
11       dfu-prefix [ -T | -L ] --delete DFU_FILE
12       dfu-prefix --help
13       dfu-prefix --version

DESCRIPTION

16       The  program  dfu-prefix  can  be used to add, check or remove a prefix
17       used by certain hardware manufacturers.  The Stellaris format  from  TI
18       and the LPC format from NXP is supported.
19
20       Note  that a standard DFU firmware file has no concept of a prefix, and
21       a DFU host tool like dfu-util passes the prefix on  to  the  device  as
22       part of the normal firmware payload.
23
