资源说明：flash utility for NXP LPC17xx ARM CM3 series on-chip bootloader
2011/01/30
lpcflash (beta) - an opensource flash utility for NXP LPC17xx ARM CM3 series
Currently supporting:
- boot rom/on-chip serial bootloader.
- all lpc1700 boot rom loader compatible bootloaders, such as the usb cdc secondary bootloader included in
the opensource LPCboot Suite (will be released soon)
lpcflash was written by Thorsten Schroeder and is released under the 2-clause BSD license. Even though it is released under a very flexible and free licence, feedback and feature requests are highly appreciated.
PLATFORMS
lpcflash was tested under Mac OSX 10.6.6 and Ubuntu 10.04 LTS. Target platforms are all LPC1700 based ARM Coretex-M3 processors.

FEATURES
+ Erase all flash ROM sectors
+ Erase selected flash ROM sectors/ranges
+ Dump/Read flash ROM and SRAM memory (if not protected by CRP) by sector/ranges
+ Dump/Read flash ROM and SRAM memory (if not protected by CRP) by addresses/ranges

Everything that is specified within the LPC17xx user documentation (ISP/IAP (flash) memory programming) has also been implemented in the USB CDC secondary bootloader firmware to be able using lpcflash also with this opensource bootloader skeletton (this also allows some kind of crypto layer for integrity checks of the firmware etc).
EXAMPLES:
1) Erase all sectors on an LPC1756 using the on-chip bootloader via serial line
$ ./lpcflash -l /dev/cu.usbserial-A1004cdd -b 115200 -e -A

Why?
The Official FlashMagic Tool for this task, which is recommended and referred to by NXP is available only for Microsoft Windows operating systems. There is no sourcecode available for porting it to different platforms, and the usage scenarios are quite restricted for non-paying customers. The free FlashMagicTool version is quite restrictive. LPCFlash utility is available as source code under the BSD license. It has been tested with Mac OSX and Linux. A complete list of supported platforms is available in the source code.
Where?
Please be aware, that this version is a very early beta testing version. Please send wishes, recommendations, bug-reports and comments to me, using email. Every feedback is highly appreciated!
What else?
I'm also working on an open-source LPCboot Suite
Support?
Hardware and Developer Boards are expensive. Hardware donations are highly appreciated...
