Unfortunately, Atmel<\/a> does not ship a hex file for their STK500<\/a> development system that could be used to update the firmware using 3rd party tools like avrdude<\/a>. Instead, an encrypted ebn<\/code>-file comes with the latest Atmel Studio<\/a>. The tools that is used to flash the firmware onto the ATmega8535 is a bit dull, though.<\/p>\n

Preparing serial connection<\/h2>\n

First, hook up the DB9 port on your STK500 that is marked as RS232 CTRL<\/strong> to your PC. Since the flash tool AvrProg.exe<\/code> only searches for devices on COM1<\/strong>, make sure that you connected it to COM1 or if you use a USB-to-Serial converter, change its address to COM1 (Device Manager → Right-click on the COM port you wish to reassign → Properties → Port Settings → Advanced → COM Port Number → COM1). The port settings should read as 9600 8N1<\/strong>.<\/p>\n

Preparing the STK500<\/h2>\n

Now, power off the STK500 and make sure, the push button labeled PROGRAM<\/strong> is pressed while turning on the power again. The LED labeled STATUS<\/code> shouldn’t be lit permanently (like it would in normal operation mode).<\/p>\n

Flashing the firmware<\/h2>\n

Startup Atmel’s flash tool AvrProg.exe<\/code> that is installed along with Atmel Studio<\/a>. The default installation location is %ProgramFiles%\\Atmel\\AVR Tools\\AvrProg\\AvrProg.exe<\/code>.
\n%ProgramFiles%<\/code> is localized and depends on your architecture. It’s most likely going to be C:\\Program Files<\/code> or C:\\Program Files (x86)<\/code>.<\/p>\n

\"Load<\/a>

Load the firmware file using the ‘Browse’ button and flash it.<\/p><\/div>\n

Next, load the STK500.ebn<\/code> firmware file by pushing the Browse<\/code> button. The default location is %ProgramFiles%\\Atmel\\AVR Studio 6.0\\tools\\STK500\\STK500.ebn<\/code>. After hitting Flash → Program<\/code>, a progress bar should appear and shortly after the status indicator should tell you that the devices has been successfully programmed. <\/p>\n

\"Device<\/a>

Device was successfully programmed.<\/p><\/div>\n

If you restart the STK500<\/strong> by turning off the power and turning it back on again, the firmware should be up and running. You can double-check with avrdude, for example.<\/p>\n
