1.1 Connection setup
Connect the USB cable from the PC to the Starter kit. The Starter kit is powered by the PC via the USB cable
(5 V). Check if the mode LED (LED3) and the power LED (LED2) are turned ON.
Figure 1 Connection between PC and starter kit
1.2 Power up
When powered ON, the device will start executing the pre-installed firmware, which is indicated by the blinking
user LEDs (LED1 is controlled by core Arm® Cortex®-M0+ (CM0+) and LED4 is controlled by core Cortex-M4
(CM4)).

Note: To indicate that the starter kit is powered ON and the USB controller is starting in the correct
mode, the amber colored status LED3 must be permanently ON. But, LED3 does not indicate a
successful USB driver installation.
Figure 2 LED indicating power ON
1.3 Installing kit driver
To work with the Starter kit, the KitProg3 USB-UART driver must be installed on the system. For more details,
see the Updating KitProg3 chapter in the KitProg3 user guide [1].
Confirm that the Starter kit is recognized as a KitProg3 device on Windows (open Device Manager, follow the
menu path View > Devices by container) as shown in Figure 3. This completes the hardware setup.
Figure 3 Viewing KitProg3 driver in Device Manager
Note: Do not press SW3. Pressing SW3 changes the mode of the USB controller. This is necessary only for
upgrading the USB driver firmware and other activities. For more details, see the KitProg3 user
guide [1].
For more information related to the Starter kit, see the Traveo II Starter Kit User Guide [2].

SDL and IAR EWARM setup
2SDL and IAR EWARM setup
This section explains how to run an example from the SDL on the Traveo II Starter Kit using the IAR C-SPY
debugger.
2.1 SDL environment setup
Download the latest SDL for the Traveo II Starter Kit on the target system. Install the SDL outside the default
Program Files to allow the IDE to access and create temporary files. Figure 4 shows the sample path.
Figure 4 SDL 7.0.0 top-level directory
2.2 IAR EWARM setup
Open the Readme.pdf from the root folder of the SDL and use the same link to download the version of IAR
EWARM supported by the SDL.
Download the software and run the installation (note that the installation might take some time). When you
open the IAR EWARM for the first time, select the license in the License wizard. If you do not have the license, it
is strongly recommended to register for Code size limited license type. See Figure 5.
Note: IAR EWARM v8.42.1 is only for reference; always use the IAR EWARM version supported by the
specific SDL release.

2.3 Connection setup
There are two debugging methods with IAR EWARM:
1. Debugging with code downloaded on to RAM
2. Debugging with code downloaded on to the FLASH memory (described in this document)
SDL supports three types of workspaces under FLASH memory debugging as listed in Table 2.

as master workspace in
multicore configuration.
Note: Both CM0+ and CM4 can do normal code execution, but from an architectural point only CM4 is
considered as the application core. After a reset, the default core is always the CM0+ core. To
enable the CM4 core, CM0+ must call Cy_SysEnableApplCore (). In the SDL, this is usually done
within main_cm0plus.c.
Before downloading and debugging with the multicore master project, you must build the multicore slave
project for the application core (which is CM4 here).
Open the master workspace (dual core CM0+ and CM4 workspaces) for multicore debugging. The slave
workspace (single core CM4 workspace) will automatically open from the master workspace when you click
Download and Debug.
2.3.1 Debugging with single core CM0+ workspace
1. Start IAR EWARM and open the SDL template workspace file:

6. Place a break point in the SystemInit()API in the CM4 core workspace. CM4 core will start executing after
being enabled by CM0+ core. You can debug both cores simultaneously.
Note: To place a breakpoint at the target instruction, click the white space between the editor window
(left pane) and the workspace window (center pane).

7. Now, click the Go icon in the CM0+ workspace to start execution. After executing
Cy_SysEnableApplCore(), CM4 core will be enabled and the execution will reach the breakpoint in the
CM4 workspace. You can now continue to debug the code from CM4 core.

Troubleshooting
3Troubleshooting
This section explains possible issues and the workarounds.
3.1 Connection troubleshooting
Error: Starter kit is not detected on the target system.
•Connect the USB cable that comes with the Starter kit. Other USB cables may not connect data lines.
•Make sure LED3 is ON (CMSIS-DAP mode). If not, press SW3 to change the KitProg3 device mode.
•Make sure jumper R11 is closed.
3.2 Driver troubleshooting
Error: Driver is not detected on the target system or “KitProg3” is not visible
For more information on the supported driver, see the KitProg3 user guide [1].
3.3 Debugger troubleshooting
Error: While programming Traveo II device, CMSIS-DAP device is not found.
Check the USB cable connection and the state of LED3 (LED should be ON for CMSIS-DAP mode).
3.4 Key points
•CM0+ core should be running while debugging with CM4 in single core mode. CM0+ core enables the CM4
core by calling the Cy_SysEnableApplCore() API.
•CM4 core workspace (tviibe1m_flash_cm4_mc_template) should be built before building the dual core
workspace (tviibe1m_flash_cm0plus_cm4_template).
