The macro FSL_FEATURE_FLEXCAN_HAS_ERRATA_8341 is not defined.

The macro FSL_FEATURE_FLEXCAN_HAS_ERRATA_8341 is not defined. This means that the code activated by this macro can never be used. Can it therefore be removed?

Discussion: The errata is actually valid for various Kinetis controllers. Shouldn't it therefore be set in the associated feature files? On the other hand, the code of the errata is apparently not needed if it is not active anyway.

Hello @william-tang914 ,

thanks for the feedback.
Errata 8341 is only present in older Kinetis controllers as far as I know. The problem has been fixed in the iMXRT family.
Shouldn't it then also be activated for the existing controllers?

I will double check whether Errata 8341 is applicable to Kinetis controllers which are supported by repo.
Thank you for your advice.

It is at least applicable in the Kinetis KV-Family. From the Errata of the KV5x:
