# dfu-prefix(1)

add, check, or remove special firmware file prefix

## NAME

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

## SYNOPSIS

**dfu-prefix** \[ **-s** *address* \| **-L** \] **--add** *DFU\_FILE*

**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**
