Hi @hdvietnam999,
Can I check what is the environment set up? What is the Arduino IDE version and SDK version you are using?
Thank you.
Hi @hdvietnam999,
May I know what is the version of your Arduino SDK? For example 4.0.8 etc?
What example are you running when you face this issue?
Have you tried reinstalling the SDK? Also can you try to remove the arm-none-eabi\bin from the path.
Thank you.
