AM2612: Issue regarding AM2612 protocol stack and Flash memory usage Problem

Part Number: AM2612

Hi experts,

When using the protocol stack for the AM2612, our customer discovered a bug that affects program execution when the 4MB area preceding the Flash is being erased. However, the actual program is only programmed within the first 3MB.
Specific Questions:
  1. What content is intended to run in the remaining space before the 4MB mark?
  2. What is the minimum required size for this space?
  3. Is it possible to change the memory location being used, and if so, how can this configuration be modified?

Thanks
