Target Board
SmartFusion2 Development Kit board (SF2_DEV_KIT) Rev C (or later).
Design Overview
This design example demonstrates the execution of basic read and write operations on the SPI flash
present on the SmartFusion2 Development Kit board. This kit has a built-in Atmel SPI flash memory
AT25DF641, which is connected to the SmartFusion2 microcontroller subsystem (MSS) through
dedicated MSS SPI_0 interface.
Read and write data information is displayed using HyperTerminal which communicates to the
SmartFusion2 MSS using the MMUART_1 interface.
For more information on SPI, refer to the SmartFusion2 Microcontroller Subsystem User Guide.

Configuring Serial Terminal Emulation Programs Tutorial for configuring the HyperTerminal,
TeraTerm, or PuTTY.
The HyperTerminal settings are as follows:
–
57,600 baud rate
–
8 data bits
–
1 stop bit
–
No parity
–
No flow control

Step 6: Connecting the ULINK-ME to the Board and PC
This section describes the connection between the SmartFusion2 Development Kit board, ULINK-ME,
and host PC. Use the appropriate settings for the board that is in use.
1. Connect Pin 2 and Pin 3 on the jumper J93 on the SmartFusion2 Development Kit board.
2. Connect the USB A-Mini B cable between the host PC and the SmartFusion2 Development Kit
board. This is used to display the HyperTerminal communications.
3. Verify that the ULINK-ME debugger is connected to the SmartFusion2 Development Kit board
RVI Header as shown in Figure 36 and also to the host PC through a USB A-Mini B cable. The
ULINK-ME adapter has one LED that indicates connection status in the following ways:
Blinking slowly indicates that ULINK-ME is ready to communicate with the debugger.
–
Blinking speedily indicates that the target board is executing the program under debugger
control.
–
Remaining ON during debugging indicates that the debugger has halted the target board.
–
Remaining ON during download indicates that target download and verification is in progress.

5. The Step Level Debugging can be performed before running the application using Run. These
can be accessed from the Debug menu or on the Keil uVision workbench as shown in Figure 45:
Figure 45 • Keil uVision Workbench - Step Level Debugging
Source code can be single-stepped by selecting from the Debug menu Debug > Step, Debug
> Step Over, Debug > Step Out or by selecting the respective options from the Keil uVision
workbench as shown in Figure 45. Observe the changes in the source code window and
Disassembly section. Performing a step over provides an option for stepping over functions.
The entire function is run but there is no need to single-step through each instruction
contained in the function.

–
Select Debug > Step Out to exit the instruction in stepping mode.
6. Add breakpoints from the Debug menu in workbench to force the code to halt, start Debug
session, and then single-step and observe the instruction sequence.
7. Close uVision using File > Exit.
8. Close the HyperTerminal using File > Exit.
Conclusion
This tutorial provides steps to create a Libero SoC software design using the System Builder. It describes
how to build, debug, and run Keil uVision application. It also provides a simple design to access the SPI
flash.
