SPI Bootloader - Mega or DUE

there is possibility to load compiled sketches ( binary programs) to Due by SD card ?.

Some time in field difficult to load program by Arduino software instead of that copy the compiled sketches to SD card and from SD card to Mega or Due by SPI port ?.

so easy to update the firmware in filed ..

Similarly how nextion display firmware update


This project let you upload a compiled sketch from an SD card to an Arduino through the serial port. Just like a PC uploads a sketch (except it does the Reset directly rather than using the DTR line).

Hello, we have an Arduino Mega2560 available
at https://www.mercari.com/us/item/m17664631034/?ref=search_results that comes preinstalled with a microSD flash installer while still supporting updates through SPI.

thanks ..........interesting
