6 Introduction to Development Board µ-controller KIT Sensors Display EVK1100 Peripherals Evaluation kit and development system for the AVR32UC3A family EVK1100 is a fully functional embedded computer system. Circuit board has a flexible power system that accepts 8-20V DC input and can be operable via USB port. The EVK1100 embeds an Atmel Data flash (8MBytes) and a SDRAM (32MBytes). Several communication interfaces are available on the EVK1100: RS232, USB and ETHERNET. 6

15 Running an Example Project Click File >> New >> Project >>AVR32 Example Project Workspace creation Project creation Project building Target Creation & Loading program Running your own Project Click File >> New >> Project >>AVR32 C Project From Template 15

16 Building a Project Select the project from the project plan (on left side of the window) and right click Click Build Project Workspace creation Project creation Project building Target Creation & Loading program Build complete for project myproject Debug directory will be added in the workspace myproject.elf will be created in the Debug directory and is ready to be loaded in the controller 16

17 For Programming EVK1100 there are three listed methods available, (Note: we can use two among them) In system Programming (ISP) Programming Via JTAG port Self Programming via One chip BOOT program Tool for using programming is JTAG or USB cable (for ISP) JTAG ICE mkii Workspace creation Project creation Project building Target Creation & Loading program 17

18 For Programming EVK1100 we need to add a Target Scan the target as shown in Picture Workspace creation Project creation Project building Target Creation & Loading program 18

19 Configure the target device i.e JTAGICE mkii for downloading your program Workspace creation Project creation Project building Target Creation & Loading program 19

20 Loading Code in the Micro-controller Loading through USB DFU Loading through JTAG On EVK1100 Press the joystick downwards and hold it. Now press the re-start button to put the device in programming mode Workspace creation Project creation Project building Target Creation & Loading program On AVR Studio Right-click on target for USB-programming and click program. Browse the target file and press ok in newly appeared window to start loading the program 20

21 Loading Code in the Micro-controller Loading through JTAG Workspace creation Project creation Project building Target Creation & Loading program Right click on JTAGICE mkii and click on Program. Browse the target.elf file and press ok to start loading 21
