NAME
lpcprog - NXP's LPC micro-controllers flasher
SYNOPSIS
lpcprog -d serial_device -c command [OPTIONS] ... [FILE]
DESCRIPTION
Use ISP protocol to flash LPC micro-controllers over serial line.
For all commands the target micro-controller must be in ISP mode and waiting for synchronisation ISP
command (default state when entering ISP mode). See ISP MODE AND CODE READ PROTECTION section for more
details.
A FILE argument must be given for dump and flash commands. For flash command this file is the data
(program) to be written to LPC internal Flash memory. For dump command, it will store the actual content
of the LPC internal flash memory.
Mandatory arguments to long options are mandatory for short options too.
-p, --parts==PARTS
Use PARTS as parts desription file instead of the default ones. See PARTS DESCRIPTION FILES
section for more information on default parts desription files and order of precedence.
-d, --device=DEV
Use DEV as host serial line to program the target. Full path must be provided. Device node files
are usually located in /dev/ directory.
-c, --command=COMMAND
Command to execute. COMMAND must be one of id, dump, flash, blank or go. See COMMANDS section for
commands description.
-b, --baudrate=BAUD
Use BAUD as the baudrate for communication with the target device. Defaults to 115200.
-t, --trace
Turn on trace output of serial communication with target device
-f, --freq=FREQ
Use FREQ (KHz) as the oscilator frequency of target device. Defaults to 10000 KHz
-n, --no-user-code
Do not compute a valid user code for exception vector 7. See USER CODE section.
-h, --help
Display help information and exit
-v, --version
Display version information and exit
COMMANDS
The command must be one of id, dump, flash, blank or go.
id The id command displays the LPC part identification ID, the uid (unique ID), and the bootloader
version of the connected target device.
dump Dump the whole connected target's flash memory content to the given file. This command requires a
file argument.
flash Flash the content of the file given as argument to the beginning of the connected target's flash
memory. Automatic computation of the User Code is made and User Code is stored in the 7th
exception vector. Use -n option to prevent User Code modification. If you need to write your file
to a different flash section, use the lpcisp tool.
blank Erase the whole flash.
go Unsupported Yet. Reset the target using hardware reset button or power cycle the device to start
the program.
PARTS DESCRIPTION FILES
Default parts description files are /etc/lpctools_parts.def or ./lpctools_parts.def The parts description
file is parsed for LPC device description for dump, blank, and flash commands. If none of the defaults
exist and no existing file is supplied using -p option, these command cannot execute. If the part
description is not found in the first found file, the command will not execute either. If no -p option
is provided, the program looks for lpctools_parts.def in the current directory first, and then in the
/etc/ directory.
The content of parts description files is a list of LPC parts description. Each line holds one part
description. Lines starting by # are comments. Refer to the default file found in the /etc/ directory
for more information on the line format.
USER CODE
A valid User Code is requiered by the LPC bootloader to start the internal user program. User Code is
considered valid if the reserved exception vector location 7 (offset 0x 0000 001C in the vector table)
contains the 2’s complement of the check-sum of table entries 0 through 6. This causes the checksum of
the first 8 table entries to be 0.
If the signature is not valid the LPC enters ISP mode.
The default behavior of lpcprog is to compute a valid code for the 7th exception vector and modify the
programed binary data to include this valid code. You can prevent this by using -n option.
ISP MODE AND CODE READ PROTECTION
Code Read Protection is a mechanism that allows "the user" to enable different levels of "security" in
the system so that access to the on-chip flash and use of the ISP can be restricted. When needed, CRP is
invoked by programing a specific pattern in flash location at 0x0000 02FC. IAP commands are not affected
by the code read protection.
If your device Does not enter ISP state, or if some commands do not succeed, it may be because the CRP
mechanism is in use on your device.
Code Read Protection will not be implemented as it goes against the license of this tool and against the
free software philosophy.
