FIRMWARE UPGRADE:
TROUBLESHOOTING GUIDE:
TIP:
the following steps must be followed. Make sure that programmer contains
a valid log, no matter its contents. Disconnect the programmer, then press
the button, and wait for RED LED to blink for error. After that the clock
output will stay activated.
All AVR-ISP500 devices contain a built-in boot loader for easy firmware
upgrade. Device enters boot loader mode if the application FLASH section is
corrupted. To force the device to enter boot loader mode for manual
firmware update do the following:
Button can now be released. The device will stay in boot loader mode until
it is power cycled.
All boot loaders implement 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 serial port settings for the AVR-ISP500-ISO boot loader
are: 9600 baud/sec, 8 data bits, no parity, 1 stop bit. The AVR-ISP500-
TINY/MASS/NANO boot loaders implement a USB virtual serial port that is
baudrate 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.
Problem: AVR Studio cannot find my programmer.
Probable causes and solutions:
1. Disconnect the programmer from any power source (external
2. Press and hold the button.
3. Power up the device by connecting it to USB.
4. Device now must be in boot loader mode, indicated by the LED light

sequence:
Look whether the programmer is listed in Device Manager under the
“Ports (COM & 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.
programmer might be in firmware upgrade mode. Go to the firmware
upgrade section for more details.
Your serial port number might be too high. Check the manual
section “Installing drivers” for more information on assigning serial
port numbers. Also go to AVR Studio menu “Tools->Options” and set
the “Number of COM ports to try” field to at least 20.
Remove all applications that might be using or scanning your
computer's serial ports, including any serial port monitors. They
might mess up the STK500v2 communication between AVR Studio
and the programmer.
