Hello,

I need to encode the TI boot loader that is uploaded via UART.

Is it possible? if so, can you refer me to where and how I should start doing it?

Best regards,

Can you elaborate what you mean "encode the TI boot loader that is uploaded via UART"? If you mean to revise serial boot loader in ROM, it's not possible.

First,

I want to alter the boot so when I transmit the second time the boot via UART it will be encoded with AES.

Or any other encryption. That way no one on channel could understand the message.

Next, I want to certificate sign it. So, only I can upload the boot and not Eve.

Best Regards,

Vitaly

I suppose you have to write your own boot loader instead of ROM serial boot loader.

Thank you for your quick response.
Can you give me a link to some documentation?
or example?
or some tips that will make it a little easier task?
