Enabling code coverage on Zephyr SDK #513
-
|
Hi, I am performing an activity that requires to enable code coverage on Zephyr toolchain to actually show how much of SDK code (in particular gcc) is being stressed by Zephyr build process. I did modify the configuration (see attachment) and build completes successfully but unfortunately no coverage files are produced. Could you please help to verify if my configuration is correct? Thanks and Regards, |
