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. This driver is part of
a firmware package and must be installed manually. Optionally further information about KitProg3 see [1].
To install the KitProg3 USB-UART driver, do the following steps:
1. Download firmware-loader package
2. Extract the package.
3. Depending on your operating system, browse fw-loader\bin\drivers\KitProg3\KitProg3UART.
4. Right-click the file “KitProg3UART.inf”and execute “Install”. Then the driver is being installed.
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.

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™ T2G 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™ T2G starter kit using the IAR C-SPY
debugger.
2.1 SDL environment setup
Download the latest SDL for the TRAVEO™ T2G 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 a 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 Verify installation by quick hands-on
The starter kit is now ready to use after a successful environment setup (USB driver installation, SDL
installation, and IAR installation). To verify the installation and setup is complete, quickly walkthrough the
following steps:
1. Connect the USB cable from the PC to the starter kit, LED2 and LED3 should be ON.
2. After power-up, LED1 and LED4 will start blinking from the pre-installed firmware on the kit.
3. Start IAR EWARM and open the SDL template workspace file:
tviibe1m\tools\iar\flash\tviibe1m_flash_cm0plus_template
4. Select the workspace revision starter_kit from drop-down list under Workspace.
5. Click Project from top menu and select Rebuild All.
6. Check for the successful build from the Build tab at the bottom left corner in IAR window.
7. The kit is already running a pre-installed firmware on it so we can connect to target CPU (TRAVEO™ T2G) by
selecting Attach to Running target option from the Project menu.
8. The debug log shows the interface and device information in the Debug tab at the bottom left corner.
9. Click pause to check the CPU execution, LED1 will stop blinking due to the pause action.
10. Now click the stop debugging button to detach the target.
11. Close the IAR window and reset the starter kit using switch SW2.
Note: In case of problems, see Troubleshooting.

There are two debugging methods with IAR EWARM:
•Debugging with code downloaded on to RAM
•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 3.

Details
Single core CM0+ workspace
“tviibe1m_flash_cm0plus_template”
No
Single
Single core download and
debug for CM0+ core.
Single core CM4 workspace
“tviibe1m_flash_cm4_mc_template”
Yes
Single
Single core download and
debug for CM4 core; works as
client/slave workspace in
multicore configuration.
Note: It is possible to
debug only with
CM4, when CM0+
executes some
code, thus
enabling CM4.
Dual core CM0+ and CM4 workspace
“tviibe1m_flash_cm0plus_cm4_template”
Yes
Dual
Dual core download and debug
for CM0+ and CM4 cores; works
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.
