SAMD21 secure bootlader

simon8

Hi all,

I'm using a SAMD21E17A and I'd like to know if I can create a secure bootloader with encrypted firmware?

I wish I could encrypt my software (aes for example) and upload it on my board, the idea is the bootloader take the firware decrypted it and run it.
This is to protect my code and prevent a user from being able to disassemble an update for example
