Firmware

Pre-installed

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)).

Getting started

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.

3Download and debug with starter kit

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.

Table 3 IAR Flash workspaces and functions

Workspace

Application

core

Number of

cores supported

Details

Single core CM0+ workspace

“tviibe1m_flash_cm0plus_template”

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.

3.1 Debugging with single core CM0+ workspace

1. Start IAR EWARM and open the SDL template workspace file:

tviibe1m\tools\iar\flash\tviibe1m_flash_cm0plus_template

Figure 8 Selecting CM0+ single core template

2. Select the workspace revision starter_kit from the drop-down list under Workspace, as shown in

Figure 9.

Note: Ignore other workspace revisions for this starter kit. The other revisions constitute the MCU

assembled on other evaluation boards (CPU board).
