Hi All


I am working on a project where we are using LPC 2420 in our product and earlier we were providing an option to upgrade the firmware of the product using serial connectivity (UART). But, now we want to provide an option to give the firmware upgrade through a USB pendrive which will contain the Hex file i.e. the firmware file.

Hardware configuration of USB is already done, but I am not able to find a solution as in how to proceed further with reading the file from the pendrive and reprogramming the external serial flash.

Request you to please help and suggest on how to proceed further.
