Let's say if I have two partition with two programs,

I want to choose which partition to boot based on a GPIO status during power up, can I do that?

Hi

The default bootloader has its own "logic":

but you can develop a custom bootloader, give a look to the source code for the default one:

It seems it's a little complicate for me, I used the NVS and GPIO to set the boot routine finally.
