GCov User Guide according to mcuexpresso help guideline

[HCPATEL99]

According to GCov User Guide I have setup for my board IMXRT1170(evk) in MCUXpresso IDE v11.4.0.

But I coudn't generate properly ".gcno"  and ".gcda" files.

Below setting I have done in MCUXpresso.

1) C/C++ Build/ Settings / MCU C Compiler /Debugging/ Generate Gcov information.

2) Added macro "--coverage " C/C++ Build/ Settings /MCU Linker / Miscellaneous.

After this If I build and run the application.

I got below error.

Error Description:

libgcov profiling error:/home/harsiddh/Documents/MCUXpresso_11.4.0_6224/workspace/evkmimxrt1170_mipi_dsi_compliant_test_cm7/Debug/board/pin_mux.gcda:overwriting an existing profile data with a different timestamp

Please give your guidance for same.

Thanks In Advance.

Hello HCPATEL99,

I couldn’t find mention of the GNU coverage tool gcov on the MCUXpresso documentation. However, there are very good posts on this topic on the MCUonEclipse blog.

I see that you have interacted on this blog entries with some replies so I’m adding this link in case it helps another community user.
