Hi

I am using LPC1227 in a application and i have USB connection throw FTDI ( FT232) IC to UART of LPC1227.

The application is writen with IAR compiler of ARM.

There is a application in Windows ( Visual Basic 6.0) to config and monitor the application.

So i would like to upgrade the software of the LPC1227 throw USB.

I heard about flashmagic tool.

Does anyone have used bootloader with flash magic or other tool for LPC1227?

Thanks in advance
 

The LPC1227 does support ISP using the ROM resident bootloader and UART.

You should be able to use the FT232 and control lines to control the ISP bootloader as well as load an image to FLASH.

Reference: , Section: 20.3 Boot loader, Page: 306

The boot loader controls initial operation after reset, and also provides the means to
accomplish programming of the flash memory. This could be initial programming of a
blank device, erasure and re-programming of a previously programmed device, or
programming of the flash memory by the application program in a running system.
Click to expand...

The NXP ISP bootloader is supported by Flash Magic or you could write your own routines and incorporate them into your app.
