Introduction to PTK Development Board

STM32F207 is a SoC consisting of a Cortex-M3 Core, built-in flash storage, and many other peripherals. The core can run up to 120MHz. The on-chip memory includes a flash of 256KB and a SRAM of 128KB.

Cortex-M3 processors are a family of 32-bit ARM-based processors for highly deterministic real-time applications. It implements the ARMv7-M architecture.

Nested Vectored Interrupt Controller (NVIC), Memory Protection Unit (MPU), … It has 3-stage pipeline supporting Thumb/Thumb-2 ISA.

Memory Mapping

The address space of STM32F207 is split into eight 512MB blocks. Block 0 maps the flash memory. Block 1 maps the main memory. Block 2 maps MMIO for peripherals. Block 3/4 maps external devices

using static memory interface. Block 5 maps control registers of

the flexible static memory controller(FSMC).

Block 7 maps internal registers ofthe processor core.

Building and Running (1/2)

Step 1: download and extract the examples PTK_Examples.zip on Windows XP.

Step 2: open the serial console, i.e., putty. Please set the speed (baud rate) to 115200bps.

Step 3: open the following workspace in IAR Embedded Workbench IDE. PTK_Examples\ePBB\Applications\Projects\PTK-STM32F207\EWARM-V6\OS_None\base_uart\demo.eww

Tips: If the system cannot link to STM32F207, please download the Jlink driver, and

install it. You can use other workspaces in OS_None examples, such as base_7seg, base_button, base_buzzer, base_light, base_tempature, etc.

Building and Running (2/2)

Step 4: compile the project by clicking the button “Make”.

Step 5: download the program to the target by clicking the button “Download and Debug”.

Step 6: click the button “Go” or press the key “F5” to continue the execution. You will see the message “Hello World!!!” on the serial console.
