Running code from external memory in LPC1788!

Thank you for your help. I want to mentioned some issues:

1- It is true that takes about few weeks (about 4 six month) to implement this security for testing and some other issues. But it is done for once. If all things will be automated, there is no concern about allocating extra resources. Because the system have alarms for probable faults and are able to recovery itself in some situation. We are already doing for AVR micro-controller system.

2- considering these few weeks does not effect the cost of support. Because many things will be done automatic.

3- Please consider that you developed a software and hardware with weak security in a short time. What is your sense, if your hardware copy in a day and you can not make profit! But I think if your system has many securities, it will be hacked more time with extra costs. If we see that the software hacks after 2 years of production time. It can be reasonable than a month after production time.

4- Another thing that i believe, It is not related that how the company is big and rich. In my opinion, I, as an engineer, should have the most talent to protect my innovation. Starting from this simple security can be ended with an intelligent securities.

5- As an important things, as my opinion, stolen data from WIFI or USB flashes or something else need many times to construct and copy the production. But if the software needs many updates and supports more capabilities, It can not be supported furthermore. for example one of our earlier software was cracked because of simple encryption. After that we changed the security and by the next updates, they can not continue producing the fake software.

6- Assigning an expert team has many cost that our management system can not accept them. But they can not accept an earlier copy of the software. In this way, taking 4 weeks is really reasonable.

At the end, we want to build a system that when they try to remove a simple ICs the system can detect and generate the faults.

And finally, I do not have many experiences in electronic system (about 14 years). But i hope consider your helps and supports and design to reduce the cost of maintenance as much as possible.
