vicentegomez Thanks, but there's some example with internal flash memory? I'm stucked trying to open the explorer folder like USB sticker with the usb stack using FAT16, but until now, no sucess in this process. The Windows recognize jm60 as a MSD and storage volume. I'm seeing with wireshark the process and trying to write like a USB sticker, but, don't know a lot of about the flux of the USB code of the stack.
