Why do IMXRT header files differ from build to build?

[imxrtuser]

Hello,

I just added some code to check the reset source but got a compiler error.

The define "FSL_FEATURE_SRC_HAS_SRSR_JTAG_SW_RST" is undefined.

After looking into it I realized that the header file MIMXRT1021_features.h in our project does not include it but the example project does.

Both header files are at the same revision: rev. 1.0, 2018-11-16. The only difference in the NXP header is the Build number (used b190319, new downloaded sdk b191008).

Will this always be the case that there are changes in header/sdk files between two different builds without changing the revision number?

Kind regards,

Stefan

Hi Stefan Mitterhauser,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
After checking, I find that FSL_FEATURE_SRC_HAS_SRSR_JTAG_SW_RST is defined in the MIMXRT1021_features.h. And the version of my SDK is 2.7.0.
I've attached the MIMXRT1021_features.h and you can check it by yourself.

Have a great day,
TIC

Hello Jeremy,

thank you for you answer. I know that the SDK 2.7.0 includes the needed define. Before updating the file I was using the MIMXRT1021_features.h from SDK 2.6.1.

If you compare the two files attached to this post you can see that there were some changes but the revision history did not get updated.

If I get a new file and I want to check if anything changed to my used version I always have to compare the whole file and can not trust that the files are equal if they have the same version number.

Kind regards,

Stefan
