I am working with LPC1769 microcontroller. With help of application note AN10866 as reference to create USB secondary bootloader. LPC1769 is working fine and able to see the LPC1769 internal flash memory as removable disk.


My query:

I had a external flash memory of 4MB, which is connected to LCP1769 through SPI. I need to make this external flash memory as removable disk using the USB secondary bootloader. Could you please suggest any solution or example design to address the query.
