Segment fram_data must be defined in a segment definition option (-Z,-B or-P)

1. The answer on the internet is that the protocol stack and the IAR version are different.

2. The solution on the Internet is to change options-> link-> config-> change the connection file. How can this problem be solved?

3. Change the software version.

4. Switch to v5.6, and then I find the problem. For example, the connection configuration file is originally hooked up, which means that the original connection file is not used. It is the user's own.

5. But I have a problem. Can I write the connection configuration file by myself? How is it generated ??
