Tool/software:

Hi Ti experts,

I'm using customized board based on AM6422. Linux based on SDK 09.02.00.08 and MCU SDK based on 09_02_01_05.

I'm using CCS12.1.0 and TI Clang v3.2.2.LTS

I want to define enum type to 4bytes by following setting:

When building the project I will get the warnings about the enum type as bellow:

I can rebuild the drivers.am64x.r5f.ti-arm-clang.debug.lib and freertos.am64x.r5f.ti-arm-clang.debug.lib with -fno-short-enums to clear the warning on drivers.am64x.r5f.ti-arm-clang.debug.lib and freertos.am64x.r5f.ti-arm-clang.debug.lib.

But how should I do to clean the warning on these bellow,

#16027-D object files have incompatible enumeration types ("divsi3.S.obj in C:\ti\ti-cgt-armllvm_3.2.2.LTS\lib\clang/15.0.7/lib/armv7r-ti-none-eabihf/libclang_rt.builtins.a" = packed, "./syscfg/ti_dpl_config.o" = 32-bit)

#16027-D object files have incompatible enumeration types ("sprintf.c.obj in C:\ti\ti-cgt-armllvm_3.2.2.LTS\lib\armv7r-ti-none-eabihf/c/libc.a" = packed, "./syscfg/ti_dpl_config.o" = 32-bit)

#16027-D object files have incompatible enumeration types ("write.c.obj in C:\ti\ti-cgt-armllvm_3.2.2.LTS\lib\armv7r-ti-none-eabihf/c/libsysbm.a" = packed, "./syscfg/ti_dpl_config.o" = 32-bit)

Hello,

This issue needs to be fixed in MCU+SDK and CCS tools then only all the warnings will be cleared.

In the above issue, you have just changed enum type to short for Application and not for the drivers.

So, we need to add enum types to the drivers and the kernel make files . I added this change to the make files and fixed warnings related to drivers and kernel.

And, I am not aware how to fix these errors on the CCS side, and please look at the image below.

My suggestion is that raise a new thread about how to solve this issue on the CCS side and get updated files to fix this issue on the MCU+SDK side, and close this thread. So, that the right expert is looking at the issue and will provide suggestions for you.

Anil.

Hi Anil,

Where should I raise a new thread for CCS, could you help to create a new thread for them? Or could you route this thread to CCS team?

Thank you!

Best Regards

Hello xixiguo,

Please create new thread as how you have created this one.

So, that the new thread goes to the CCS compiler team and they can provide a reply.

Mention the issue case as the enum type has been changed in the MCU+SDK drivers and how to fix this issue in CCS tools with the above image (CCS tools warning image)

Regards,

Anil.
