CCS/AM3358: ICEv2 link issue

Hi,

Unfortunately I can't download your files from dropbox since it's against TI's file sharing policy.

I surmise you've created the two custom platforms icev2AM335x and icev2XIPAM335x. Although the contents of the files you've shared would be useful in diagnosing the build problem, it would probably be more useful for you to share your custom platform folder / files.

Why do you need a separate platform definition for the XIP case, and what is the difference between icev2AM335x  & icev2XIPAM335x? Is it the memory map and where certain code/data is linked?

Regards,
Frank

Hello Frank,

The first time I tried this it would not accept these attachments. Here are the respective zip files for the two configs.

The reason that I wanted two config files is to be able to compile to put the application into the ram vs putting the application into the NOR Flash.

icev2AM335x.zip

icev2XIPAM335x.zip

I'm unable to post those linker files by uploading them.

So here is the linker file for the execute from ram instance.

Hi Alan,

I was able to reproduce the problem with the platform definitions you shared. I need to investigate further to see if I can determine the source of the problem.

Regards,
Frank

Alan,

I see a similar issue described here: https://stackoverflow.com/questions/41879952/how-to-avoid-relocation-truncated-to-fit-from-arm-exidx

It seems the compiler is generating the .ARM.exidx section, and there is some reference to this section in the code you're linking to NOR. Apparently the address offset between DDR and NOR is too large to be encoded in the ARM instruction set, so the failure occurs.

Regards,
Frank

Hello Frank,

Thank you for the response. However, I'm still not quite there. I did manage to finally get it to link (with warnings) - so I'll include what I've done so perhaps you can direct me further.

I downloaded the file and stuck it in with the other sources. This is how I have the linker configured in the build settings.

I did a "clean" and then a build. This is the failure I'm now getting.

I see that the file is included and it link command has the correct path to the file.

From the file Debug/linker.cmd file

REGION_ALIAS("REGION_BSS", DDR);
REGION_ALIAS("REGION_TEXT", NORFLASH);
REGION_ALIAS("REGION_DATA", DDR);
REGION_ALIAS("REGION_STACK", DDR);
REGION_ALIAS("REGION_HEAP", DDR);
REGION_ALIAS("REGION_ARM_EXTAB", DDR);
REGION_ALIAS("REGION_ARM_EXIDX", DDR);

So I'm puzzled by the error message as we  are not redefining the REGION_TEXT section, just adding to it.

Do I use this script instead of the one generated (linker.cmd) or in addition to the one generated? It looks like it would be in addition to , based on it's contents.

I tried just using NORFLASH in app.cmd for the region, with success. - ie. it linked, with the the following warning message.

c:/tools/ti/ccsv8/tools/compiler/gcc-arm-none-eabi-7-2017-q4-major-win32/bin/../lib/gcc/arm-none-eabi/7.2.1/../../../../arm-none-eabi/bin/ld.exe:../app.cmd:10: warning: memory region `NORFLASH' not declared

Finished building target: "rtos_template_app_am335x_a8.out"

I examined the map and it did put main where I directed the generation.

From .map file

 .text          0x08010540       0xa8 ./main.o

Not sure why I'm unable to use your script unchanged? Any ideas?

Thanks! Any further info that would help get rid of the warnings would be most helpful.

Later,

Alan.

This is how the app.cmd  looks now.
