AM263P4-Q1: Libraries Don't Build When DebugP_ASSERT_ENABLED is 0

Kier

Part Number: AM263P4-Q1

Hello,

In SDK 10.2.0.15, as per the related question, I changed the macro to:

#define DebugP_ASSERT_ENABLED 0

Then attempted to rebuild the libraries. The make stops a number of times in a few libraries due the following types of error.

I added the following to the problem makefiles.

-Wno-unused-but-set-variable \
-Wno-unused-variable \

Please check and update the makefiles if that is the right course of action.

Hi Kier,

I get the same errors on trying to re-build the drivers library in SDK. This error can be bypassed by using these flags in makefile:

-Wno-unused-but-set-variable \
-Werror \
-Wno-unused-variable \

Add these to `CFLAGS_common` list and try to clean and re-build (Tested with the v26.x SDK but should work with v10.02 as well.

Regards,
Shaunak

Hi Shaunak,

Thanks for the confirmation.

Can you arrange for the next version of the SDK to include these edits please?

Thank you.

Hi Kier,

Yes, i have filed an internal JIRA: https://jira.itg.ti.com/browse/MCUSDK-15953 for the bug.

Just one footnote. I disabled debug assert in drivers and nortos libs. The object code in both lib files was indeed smaller. However, when used in a bare metal control loop running at 20kHz, I could not see any detectable reduction in execution time.

Would you always expect a statistically significant improvement? Say 5%?

Hi Kier,

I do not really think we will have a significant noticable improvement with asserts disabled. Yes, if you are using a lot of DebugP_logs, removing/disabling those will significantly reduce application execution time. Disabling the asserts would save about just 3-5 clock cycles and i dont see a lot of saving there.
