Part Number: AM5728
Other Parts Discussed in Thread: SYSBIOS

Tool/software: TI-RTOS

Hello, TI Experts,

Our customer sent us questions about SMP programming in PROCESSOR-SDK-RTOS-AM57X 05_03_00_07 .

They created the small program with SMP and tried to run on the TMDXIDK5728.

They already checked the posix-smp demo from TI recommendation like below;

http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_examples_demos.html#posix-smp-demo

But they don't have plan to use posix for their product.

So, they tried to create SMP project by using "Task_create API" reffering the below wiki.

http://processors.wiki.ti.com/index.php/SMP/BIOS#Getting_started

And they found below behavior.

- If *.cfg include below statement, their SMP code went into abort().

BIOS.customCCOpts +="-mcpu=cortex-a15 -mfpu=neon -mfloat-abi=hard -mabi=aapcs -O3 -Wunused -Wunknown-pragmas -ffunction-sections -fdata-sections -g -Dti_sysbios_Build_useHwiMacros -Dfar= -D__DYNAMIC_REENT__"

- But if we removed "-Dti_sysbios_Build_useHwiMacros" from the statement, their SMP code run properly.

Question:

- Could you tell us the detail description of the compile option "-Dti_sysbios_Build_useHwiMacros"?

- Are there any document of the compile option "-Dti_sysbios_Build_useHwiMacros"?

- Is it OK to remove "-Dti_sysbios_Build_useHwiMacros"?

Hi,

Thank you very much for your kindness.

I really appreciate your help.

We'd like to attach the CCS project.

( Please refer line 253 of test.cfg.)

We would appreciate if you check the behavior with TMDXIDK5728.

And we would also appreciate if you tell us the comment for removing the option "-Dti_sysbios_Build_useHwiMacros".

Best regards,

The '-Dti_sysbios_Build_useHwiMacros' SHOULD NOT BE USED with SMP applications.

I'm not sure how this internally managed compile symbol found its way into user code but it should never have.

I'd like to the answer to the customer.

We can find the related explanation of most options in below site.

But we cannot find any description about the option "-Dti_sysbios_Build_useHwiMacros" in below site.

Question:

- Could you tell us the detail description of the compile option "-Dti_sysbios_Build_useHwiMacros"?

The "ti_sysbios_Build_useHwiMacros" manifest constant is not documented.

It is for internal use only and should not be used by customers.
