Greetings,

You should be able to so long that your hardware is designed for such with an adequate fail-safe recovery.

Good Luck,

Sam

Greetings,

You should have first (1 or more) sector for Boot.

X sectors for application image 0

X sectors for application image 1

1 sector to be used as image selector.

You always boot from your Boot sector, and based on the image selector you should then load image 0 or image 1.

In field, you download an upgrade to a volatile memory, sanitize the download, once OK, erase the non active image and program with the new load. Once it pass Checksum verification, then you switch your image selector (last thing to do).

Good Luck,

Sam
