Is this a different design than your other thread with boot failure?

Re: Flash Encryption not working?

You could use a wake stub or custom bootloader

Re: Can I un-brick my dev board after unknowingly uploading alternate app when secure boot was enabled

If you enabled reflashable you should have the keys from when you flashed the other app or did you delete them?
