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		Usage error
