How to do the bootable image upgrade after production?

Our platform is the iMXRT1020, we are using the XIP QSPI flash as our bootable image storage, since in our design we only embed a USB-A female port, not USB-Micro OTG, could we program the bootable image through Serial Downloader, or said, to program XIP flash? Can I upload the generated bootable image through an external USB storage? or we actually need to design our own Flashloader?


Also, I wonder how could we switch the bootmode after production? since it should be switched by I/O pins, is there any soft way to switch it?


Please suggest if there is any designed solution, thanks a lot.
