TDA4VM: How to reset MCU1_1 to user defined start address when MCU1_0 running in APP?

TDA4VM: TDA4VM:How to define specific data to pre-defined section from *.bss in linker file without set #pragma DATA_SECTION

Part Number: TDA4VM

We have library code which released by thirdparty . It will generate some data which should be defined into specific memory,

Now the problem is that these data was generated into .bss or .common section like:

and the code changed to set pragma for our thirdparty might not be possible.

Do you have any idea how it could be achieved?  maybe define something like .bss.test_u8  or test_u8.bss in link file,

compiler version is

ti-cgt-arm_20.2.4.LTS

    Hello,

    To summarize, the library you received is placing code into .bss, and you do not have access to change the #pragma in the library source code to move these sections.

    And you are looking for a way to move the code section used in the library to another section. Is this correct?

    Regards,

    Erick

    Yes, just want to move several variables from *.bss section to another since some variable should be linked into nocache memory area

    I presume you want to control the allocation of the variables TI_traceBuffer0 and TI_traceBuffer1. That would allow you to specify the exact address for them. These variables are defined in the .common section.  

    Unfortunately, the linker supplies no method for doing that.  So, I filed the entry EXT_EP-11013 to request a feature be added to the linker which supplies such a method.  You are welcome to follow it with that link.

    Thanks and regards,
