Encrypted firmware form ARM cortex M0 SAMD21E17A

simon8

Hi all,

I'm working with an SAMD21E17A and I'd like to know if it's possible to create a secure bootloader for encrypted firmware. I've searched but I didn't find any useful example or tutorial. My dea is to crypted my soft and the bootloader decrypted it for example AES128 or something else.

I want to prevent a easy decompile manipulation with the bin.
