Want to read a HEX file from USB pen drive using LPC 2420

kunal thakur

Hi All

I am using ARM controller LPC 2420 in my project where I am using an external flash memory to store the firmware code.Earlier I was using serial interface to upgrade the firmware of the controller using a VB application. But now I want to upgrade the firmware of the controller directly by using USB pen drive. So can anyone please suggest how to implement this.

    So all you're changing is the way the data gets to the micro - isn't it?

    As far as programming the flash goes, where the data came from is irrelevant.

    If you want to get the data from a file on some storage medium then, obviously, you will need a suitable file system to do that - the clue is in the name.

    For USB, you will need to provide a USB Host.

    Keil middleware has USB Host and file system components:

    plenty of 3rd-party alternatives are available...
