Hi there,
What , BSP are you using , Roll back to an earlier one.
and You can use the code tags above “</>” paste it in there, you get better replys and it’s easier to read and test.
Look at the compiler output first line , Scroll over and what BSP is used., go to the boards tab, pull up ESP, use the pull-down caret to select an old one.
