Hi everybody! Is there the possibility with LPC1768 to load firmware throught an USB Memory Stick without a PC? I think that I have to implement USB MAss Storage Class in Bootloader Mode. So at reset if a GPIO is in a particular state, I enter Bootloader mode, I read the Memory stick throught File system (USB Host lite) and if there is a valid .bin file I write it into Flash. All without a PC. Freescale Kinetis has this feature. Is it possible with NXP LPC1768? Is there an application note for it?

Thank you very much

This should be doable on this part. The USB stack nxpUSBlib has a mass storage class host example for this part but it only reads sectors. You would need to incorporate a FS (chanFS) on top of it to navigate the flash drive.

Thank you for the answer.
But can I load all in bootloader? How can I do it?

Thanks

No this is not possible. You can boot up and program your flash over UART0 using FlashMagic.
