I am using an Ethernet bootloader which nicely allows to reflash the application area via a mini-HTTP server.
Everything works nice, but I am thinking how to protect the application for being stolen.
I assume that lock fuses and security bit cannot be used, as this would prevent the reflash operation from the bootloader. Another option could be to disable the JTAG port, but I can't find a way to do so (if I remember correctly, this can be done on some Mega/XMega).
Any suggestions? Or correction, if I am wrong?
