[Error message]
ICE Error No.f4f: IDCODE is not retrieved.

[Cause]
This error is output when IDCODE of DAP cannot be accessed collectly in the middle of attaching a debugger to the user system.
This error occurs only Cortex core.

[Workaround]
- nSRST signal may be unstable.
Check nSRST signal.
- Implement (IDCODE of DP) of chip maker may not be correct.
Contact the chip makeer.
- ICE-I/F signal may not be connect correctly.
Check signal conection.
If you used Cortex-M series core,
choose [MPU]-[MPU-Specific Settings]-[Other], and change "Connection detection JP" to check OFF.
- "JTAG/SWD clock" frequency may be too high.
Choose [MPU]-[MPU-Specific Settings]-[User System], and change "JTAG/SWD clock" value to 1MHz.

[Caution]
In the case this error occurred, re-initialization of ICE and user system may require.
