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

kunal thakur over 7 years ago

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.
