GD32450I-EVAL

3 Getting started

The EVAL board uses Mini USB connecter or DC-005 connector to get power DC +5V, which is the hardware system normal work voltage. Three kinds of different USB power supply which are USB_FS, USB_HS_ULPI, GD-Link can be chosen through JP4. A J-Link tool or GD-Link on board is necessary in order to download and debug programs. Select the correct boot mode and then power on, the LED5 will turn on, which indicates that the power supply is OK.

There are Keil version and IAR version of all projects. Keil version of the projects are created based on Keil MDK-ARM 4.74 uVision4. IAR version of the projects are created based on IAR Embedded Workbench for ARM 7.40.2. In Firmware folder, Addon and Software Pack are used to add the devices, peripherals and others to IDE. During use, the following points should be noted:

1. If you use Keil uVision4 to open the project, install the GD32F4xx_Addon.1.0.0.exe which is in \Library\Firmware to load the associated files.

2. If you use Keil uVision5 to open the project, there are two ways to solve the "Device Missing (s)" problem. One is to install GigaDevice.GD32F4xx_DFP.1.0.0.pack which is in \Library\Firmware. In Project menu, select the Manage sub menu, click on the “Version Migrate 5 Format...” menu, the Keil uVision4 project will be converted to Keil uVision5 project. Then add “C:\Keil_v5\ARM\Pack\ARM\CMSIS\4.2.0\CMSIS\Include” to C/C++ in Option for Target. The other is to install Addon directly. Select the installation directory of Keil uVision5 software, such as C:\Keil_v5, in Destination Folder of Folder Selection. Select the corresponding device in Device of Option for Target and add “C:\Keil_v5\ARM\Pack\ARM\CMSIS\4.2.0\CMSIS\Include” to C/C++ in Option for Target.

3. If you use IAR to open the project, install IAR_GD32F4xx_Addon.exe which is in \Library\Firmware to load the associated files.
