RTT log output issue
Hello,
I am using SDK v3.0.2 and toolchain v3.0.2.
After building and flashing my firmware, no logs are being output to RTT Viewer.
What should I do to resolve this issue?
Additionally, the build completes successfully, but after flashing the firmware to the board, it is not functioning at all—not only is there no log output, but the application itself does not operate.
The application worked properly with toolchain v2.8.0, but after switching to version 3.0.2, this problem started to occur.
