TMS320F28377D-EP: TMS320C28377D: F021_API_F2837xD_FPU32.lib warning #10068-D: no matching section

Sylvain,

Did you map the flash API to flash address for load and RAM address for execution in your linker cmd file?

If not, please do so and map it to the addresses that you want.

Please check the linker cmd file "flash_programming_cpu1_FLASH.cmd" available at C2000Ware_3_03_00_00\device_support\f2837xd\examples\dual\flash_programming\cpu01.

Thanks and regards,

Hi Vamsi,

yes the flash API is mapped to FLASH section: LASHMN          : origin = 0x0BC000, length = 0x003FF0, and should run in GRAM section: RAMGS0123           : origin = 0x00C000, length = 0x004000

as you can see in the linker command file "saver.cmd" I attached in my previous post. 

GROUP
{
RamFuncSection
{ -l F021_API_F2837xD_FPU32.lib}
} LOAD = FLASHMN, PAGE = 0, ALIGN(4)
RUN = RAMGS0123, PAGE = 1
LOAD_START(_RamfuncsLoadStart),
LOAD_SIZE(_RamfuncsLoadSize),
LOAD_END(_RamfuncsLoadEnd),
RUN_START(_RamfuncsRunStart),
RUN_SIZE(_RamfuncsRunSize),
RUN_END(_RamfuncsRunEnd)

I have used the flash_programming_cpu01 as an example. but I still have a " #10068-D no matching section saver.cmd /SAVER_TRV_PROTOA_US101_Debug line 109 C/C++ Problem" and the librairy objects are outside the expected zone as you can see (extracted from .map file):

00089307    00000259     F021_API_F2837xD_FPU32.lib : FlashStateMachine.obj (.text:__Fapi_setupFlashStateMachine)

I do not understand the warning and why the linker comad file is ignored

Sylvain

Sylvian,

Not sure whether or not we both are looking at the same linker cmd.

In the linker cmd that you shared in your first post on this thread, RAMLS2 is used for flash API and not RAMGS0123.  Below is what I see from our linker cmd file.

GROUP
{
RamFuncSection
{ -l F021_API_F2837xD_FPU32.lib}

} LOAD = FLASHMN, PAGE = 0, ALIGN(4)
RUN = RAMLS2, PAGE = 1
LOAD_START(_RamfuncsLoadStart),
LOAD_SIZE(_RamfuncsLoadSize),
LOAD_END(_RamfuncsLoadEnd),
RUN_START(_RamfuncsRunStart),
RUN_SIZE(_RamfuncsRunSize),
RUN_END(_RamfuncsRunEnd)

Also, why are you mapping code to page 1 (RAMLS2) in the above snippet?  Please move it to page 0.  

And also use ALIGN(8) for all the flash mapped sections.

What is the compiler version that you are using?  As you know, the latest compiler versions need you to use .TI.ramfunc section instead of ramfuncs.  Is RamFuncSection your custom section?

Thanks and regards,

Vamsi
