lpcflash (beta) - an opensource flash utility for NXP LPC17xx ARM CM3 series
# lpcflash (beta) 2013/09/08
### 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)
- 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 <ths (at) dev (dot) io> 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
#### 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.

Why?
#### 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.
