After the boot loop problem reported I am not surprised to have an issue again. This time it does not even compile. I tried the Basic Readings example which compiles and runs on other boards. Attached is a text file of the verbose compiler error output. I am also updating my other post. I have many Qwiic boards including IMUs and this is the only one with a problem.
