Quick Start Guide/Flashing

Requirements

• the previously selected board, e.g. AVR NET-IO, ready built and (hopefully) tested
• an ISP-Programmer of your choice supported by avrdude
• ISP connector cable

Flashing with avrdude

Avrdude offers several options. We will look on the most important, to make basic flashing of ethersex possible.

• The chip you use, should be m32 for the ATMega32 in most cases: -p m32
• Debug messages: -v
• The protocol spoken with the programmer, for the Evaluation-Board: -c ponyser
• The serial port the programmer is connected to: -P /dev/ttyS0
• The command you want to execute: -U flash:w:ethersex.hex

After you checked all options and adjusted them to your settings you should have a command like this:

 avrdude -v -p m32 -c ponyser -P /dev/ttyS0 -U flash:w:ethersex.hex

Writing the Bytes

• Disconnect the power from the NET-IO
• Connect your ISP cable to the programmer and the Net-IO
• Reconnect the power and connect your programmer to the PC
• Execute the command you assembled earlier
• Congratulations! If avrdude finished without any error you successfully flashed ethersex to your Net-IO!
• Disconnect the power and the programmer from the Net-IO
• Reconnect the power, your Net-IO should boot up with ethersex
