MPC5674F Processor and 32-bit address

[thiefjack]

Homework Statement

I'm not sure where to start with the following question. Can anyone point me in the right direction? It is part of some challenging questions I was given and I'd like to try to learn how to solve them.

Assume unsigned32 X; Consider the MPC5674F processor. The 32 bit address of the Flash B Shadow Block starts at X. Use whatever resources you have to find X.

Homework Equations

None.

The Attempt at a Solution

I'm not sure even where to start! I was hoping someone could point me in the right direction towards at least starting off.

It's not clear what the goal is here, is it to find where Flash B is located in the memory address space? Is it restricted to a range of addresses or could it be anywhere? Assuming that there's some way to write and read memory to identify the Flash B address range, it probably wouldn't be a good idea to be writing and reading random locations in the memory address space, since that it could mess up other devices that also use a part of the memory address space.

Yes, the goal is to find where Flash B is located in the memory address space.
However, I have no idea as to where I could start looking.

If there is no specified range, then you need to probe every address that is a multiple of the size of Flash B, assuming there's some handshake sequence that works with any address within range of Flash B. I don't like this idea because poking a random memory locations could mess up something else.

I would suggest starting by researching the MPC5674F processor and understanding its architecture and memory mapping. This will give you a better understanding of how the processor handles addresses and how to locate the Flash B Shadow Block starting address.

Additionally, you can refer to the processor's datasheet or technical manual for specific information on memory mapping and address ranges. You can also use tools such as debuggers or memory mapping software to help locate the starting address of the Flash B Shadow Block.

Furthermore, understanding the concept of unsigned integers and their storage in memory can also be helpful in solving this problem. You can also try breaking down the problem into smaller parts and using trial and error to find the starting address.

Overall, the key to solving this problem is understanding the processor's architecture and using available resources to locate the starting address.
