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 Table A 2 Problems while using KD30 After stepping a few e Changes were made to UART1 SFR s instructions KD30 hangs Breakpoints do not seem to e KD30 is in free RUN mode From the Init window work Environment Init change RUN mode to Sample Mode KD30 locks up cannot stop e Changes made to UART1 SFR s program or e Ensure no limitations in Section 6 were violated Communication error e Rerinitialize the system without closing KD30 See note message is displayed below e Doahardware reset User program runaway may be corrupting the kernel RAM interrupt vectors flags etc Close KD30 hit reset button on the SKP8CMINI to reset the board and then restart KD30 Download problems e Filenames or directory names contain spaces or special charact
3. Connect to Target When the message Can t connect with the target is displayed after KD30 startup there are several reasons that may cause this message to appear Each cause and the corresponding countermeasure are discussed below e The SKP is not connected correctly Please connect the ICD to your PC Note Regardless of whether the ICD is bus or target powered please connect target board to ICD board first before plugging the USB cable to your PC Please see section 4 on system SKP8CMINI 13 connectivity e The ICD has no power Power LED on ICD is off Please ensure that the Power Mode switch on the ICD is on the USB side In Target position the ICD is powered from the target side e USB was not selected on the Init dialog box Please select USB from the Init dialog box that is displayed right after you start KD30 e The selected MCU on the ICD board and the actual target MCU R8C 13 do not match Close the error message by clicking on OK button and then click on the Cancel button of the KD30 Init window to close KD30 Make sure you select R5F21134 mcu If the MCU loaded on the ICD is different KD30 will re program the ICD to match it e The target MCU is damaged Try a different target board and see if KD30 will come up as you may have a damaged board or MCU SKP8CMINI 13 User s Manual Rev 1 0 16 22 October 2004 el REN ESAS MCU Applications Engineering A 2 3 KD30 Already Exists
