AM6422: MCU+ SDK AM64x 09.02.00.50 missing GCC build option

Angel Gavrailov

Part Number: AM6422

In MCU+ SDK 09.01.00.41 we were able to build the libs for R5F for/with GCC with the make target libs_gcc with the following procedure:

cd ${MCU+SDK install path}
gmake -f makefile.am64x libs_gcc PROFILE=debug
gmake -f makefile.am64x libs_gcc PROFILE=release

Now, in MCU+ SDK AM64x 09.02.00.50 this target is missing. Is there still a way to build the libs for gcc and what would be the workaround if not?

Thanks!

Hello Angel,

Thanks for reaching out to Texas Instruments E2E support forum.

Let me check this internally and revert back soon.

Hello Angel,

Thanks for your patience.

I have discussed this internally. The GCC libs now can't be build from the SDK.

Is there any specific use case to use GCC libs?

Tushar

Hi Tushar,

Yes, I noticed that.

Yes, we are using GCC in order to build our project, since the TI-Clang compiler does not support C++20.

I am just curious, why was this option removed from the SDK?

Regards!

Tushar: was that decision to not build GGC libs in an SDK made in conjunction with the CCS team?

Hi Jim

We intentionally removed GCC from ti.com as I do not think it is ready for prime time. Our complier teams only support TI CLANG. So for now GCC on R5 is a limited release to select customers. We will evaluate on the timelines on when we can take it broader. Likely not before late 2024.

Additionally GCC support was initially only planned for baseline MCU+ SDK, it is not available or planned yet for Industrial Comms and Motor Control SDK, so a partial offering would not have really benefitted the customers who are using all or at least 2 of these components.

If you have some specific queries on C++ 20 in conjunction with TI CLANG, feel free to open another post, I would like our compiler team to comment on it (and will route it to them)

Hello Mukul:

your response on R5 not supporting GCC on the MCU+ SDK leads me to also ask if the 64 bit Linux compiler (used on A53) is indeed GCC or not? (I think Nick Saulnier has the answer). I can understand why this can differ given the cross compilation of AM6x's different cores.

thanks

Jim

Linux is all GCC complier, no confusion there. This is strictly with respect to MCU+ SDK and RTOS compilers for R5.

If we do Free RTOS for A53, that will also be GCC based (on TI CLANG available AFAIK).

Additionally please note that if you are doing any safety related products, TI CLANG are the compilers we from the compiler qualification kits
