Put a jumper between pin 1 and pin 3 of the ICSP10 connector Power up the device by connecting it to USB Device now must be in boot loader mode indicated by the LED light sequence a RED off GREEN on b RED on GREEN off c RED off GREEN off Jumper can now be removed The device will stay in boot loader mode until it is power cycled or Boot loader implements the standard protocol XMODEM with CRC16 for firmware update User is free to use his favorite terminal client HyperTerminal minicom etc to upload the firmware images taken from our website The AVR ISP500 boot loader implements a USB virtual serial port that is baud rate agnostic As an alternative we provide a simple Windows GUI application for users who don t want to or cannot use terminal software After the firmware image is uploaded the target will blink the GREEN LED if update was successful otherwise it will blink the RED LED if firmware image was invalid or update was unsuccessful Device stays in this state until it is power cycled TROUBLESHOOTING GUIDE Problem AVR Studio cannot find my programmer Probable causes and solutions Look whether the programmer is listed in Device Manager under the Ports COM amp LPT section If it s not there then check your USB cables and hubs Reinstall the driver Check that the green LED is constantly on If not then the programmer might be in firmware upgrade mode Go to the firmware upgrade section
