no matching section warning when using memory protection

Darshan Shah

Hello all,

I am trying to make a partition software. The software is configured on Elektrobits tresos studio. I have created 3 Os applications and assigned the counters/alarms/tasks to its respective Os application. Out of the 3 OS Applications, 2 are using Privileged mode and the 3 one in non príviliged mode. This means that the 3 Os Application can only have read/write access to a specific memory partition. Hence I assigned this non privilliged mode OS application to a variable in the make file. Hence the linker sees this and should assign a particular memory area exclusively for this OS application.

The problem : I have warnings "no matching section". Though it compiles and links with a out file but I have 8 warnings (see red boxes) as shown in the attached file.

Does anybody has any idea, where the problem lies or did I miss anything when using memory partition?

Best Regards,

Darshan

Darshan,

Your screen shot is not readable (too small). Please recapture it? I guess that you saw those warnings in linking process. Would you please send the complete link command file?

Thanks and regards,

Hello Zhaohong,

Thank you for your prompt reply. I have attached the linker script file for your reference. Regarding the picture, could you please click on the picture, it should enlarge and then it is clearly visible. I tried it and could read everything.

Linker Script File : 1401.ARM-ticgt.txt

Best Regards,

@Zhaohong,

Here I have attached the linker warnings snapshot.

Darshan,

The linker warning "no matching section" indicates that the section defined in the link command file does not actually exist in the source code. For example, there is a "no matching section" warning on line82 of your link command file. A "App1_gen.obj(.data)" section is defined at line 82. I believe that there is no such compiled section in your source code. You can go back to you source and map file to check.

Please let me if the above answers your question.

Thanks and regards,

Zhaohong
