Distributing ISOMAX code securely

[dfitz]

Hi there,

We have a couple of quick questions relating to the same theme...

Basically, we were wondering if there's anyway to be able to chip out code to our dealers that sell products for us to update code on our plugapods / servopods. We are using ISOMAX for the code.
We require a way to do this without giving away the ISOMAX source files.
So, we were wondering if there's say:
- a way to upload encrypted files to the boards? <or>
- is there a compiler for the isomax code, and then a program to flash the board, so for example we could distribute the compiled file and the 'flashing' program?

Or any other suggestions that will achieve the objective of allowing people to update our code on the boards without having access to the raw source code.

Thanks,
Daniel

Maybe you could put your own boot loader in your program, then your dealers could invoke the boot loader, and download your code as binary file.

The boot loader would move itself into RAM, then do a SCRUB, then go into load mode.

That way you don't have to worry about our kernel.
