NAME

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

SYNOPSIS

dfu-prefix [ -T | -L ] --check DFU_FILE

dfu-prefix [ -T | -L ] --delete DFU_FILE

dfu-prefix --help

dfu-prefix --version

DESCRIPTION

The program dfu-prefix can be used to add, check or remove a prefix used by certain hardware manufacturers. The Stellaris format from TI and the LPC format from NXP is supported.

Note that a standard DFU firmware file has no concept of a prefix, and a DFU host tool like dfu-util passes the prefix on to the device as part of the normal firmware payload.

OPTIONS

-s, --stellaris-address address: (in combination with --add) Add TI Stellaris address prefix to file
-T, --stellaris: (in combination with --delete or --check) Act on TI Stellaris address prefix of file
-L, --lpc-prefix: (in combination with --add or --delete or --check) Use NXP LPC DFU prefix format
-h, --help: Displays a help message.
-V, --version: Displays the software version.

EXAMPLES

dfu-prefix --stellaris-address 0x0100 --add firmware.dfu: Adds a Stellaris prefix with load address 0x0100
dfu-prefix --stellaris --check firmware.dfu: Checks the file firmware.dfu for a Stellaris prefix
dfu-prefix --lpc-prefix --delete firmware.dfu: Removes a LPC prefix from the file firmware.dfu

EXIT VALUES

0: Success (also if prefix is missing)
-64: Usage error
