A.2.3 KD30 Already Exists
When a message ‘KD30 already exists’ is displayed, the usual cause of this problem is that the
KD30 application was not properly closed. Please check if KD30 is already running by looking at
your task bar. If KD30 cannot be found there, bring up Task Manager (press CTRL-ALT-DEL
once to display the ‘Task Manager’). Select KD30.exe on the ‘Processes’ list and click on ‘End
Process’ to terminate KD30.
A.2.4 Issues that may come up During Debug Operations
While using KD30 to debug user code, some issues may come up because the limitations
discussed in section 6 were not satisfied. These common issues are listed on table A.2, including
the countermeasures.

To re-initialize the system without closing KD30, try the following:
After initialization, debugging can resume. However, it is recommended that you download your
program again before debugging.
Note: If it has been identified that there are problems with the ICD, please see the ICD’s (RTA-
FoUSB-MON) user’s manual and troubleshooting.

HEW project not properly set up (startup files missing or out
of order, files added to wrong member, etc). Try creating a
new project and adding your source files to it. For details,
please see HEW user’s manual.
