[Error message]
ICE Error No.F5A: Protocol error occurred
[Workaround]
- JTAG/SWD clock frequency may too high.
Low down “JTAG/SWD clock of MPU-specific setting.
- ETM does not exist.
Change [ETM Type] from [JTAG+ETM] to [JTAG] in debugger menu [MPU] - [ETM Control] - [ETM Control].
- SWD signal may have a problem.
Check the signal quality of voltage level and signal waveform (Noise, such as reflection).
[Cause]
This error is output when using SW-DP.
MPU cannot receive normally the ICE data.
This error occurs only for Cortex core.
