Software to program LPC21xx flash memory

jimswor — Thu, 06 Apr 2017 22:29:54 GMT

I am an application software developer with a client who has asked me to develop a Windows installer for their LPC2103 and LPC2138 firmware.

The LPC processors are used in a device that may be attached to a PC via an RS-232 connector. The client is currently using a multi-step procedure for installation of new firmware, in which copying of the new firmware file is achieved using a tool called Flash Magic. They want to move away from this manual approach, to a "one-click" installer that walks the user through upgrading/downgrading firmware.

Working with embedded systems is not my area of specialization, so I may use the wrong terms and would welcome any and all feedback or assistance. To start, I am looking for documentation to help me understand how to interact with the LPC MCU in order to install new firmware. Ideally, I would like to find open source software that can handle that task or show me how it's done.

You want to use ISP (in system programming) which is described in the user manual for your part.

take a look at lpc21isp on sourceforge for open source (LGPL licensed) source

lpc21isp download | SourceForge.net

The user manuals and source code were exactly what I was looking for. Didn't know to ask about ISP - that's good to know. Thanks all around!

One can use LPCXpresso IDE for development software for LPC processors:
