Flashing ethersex

This guide assumes that you have a NETIO, made and produced by Pollin, however every step should also work with any other board supported by ethersex.

What's needed?

AVR Net-IO
an ISP Programmer, again we assume it the ATMEL Evaluation-Board made by Pollin
an 1-to-1 Cable for the ISP-Port (10-pin Connector).

Other ISP Programmers

If you have a ISP-Programmer with 6-pin port you can create an adapter. You can see the pin configuration in figure 4-1 at page 5 AVR042: AVR Hardware Design Considerations.

Warning: Pin 4 of the 10-pin connector is not used on the Net-IO. GND has to be connected to one of the other Pins (6, 8 or 10)

Flashing with Linux

Connect the 10-pin Cable to the ISP-Connector.
Plug in the power adapter of the AVR Net-IO.
If everything is connected right, the yellow LED of the Evaluation-Board is shining.

Setting the FUSE-Bits

Calculate the correct FUSE bits for your controller/setup - you can use http://www.engbedded.com/fusecalc/ for that
Important: in the condition as supplied the 644 is programmed to 8 MHz internal RC-Oscillator and the clock is divided by 8 -> 1 MHz clock speed. If an external Quarz is used, the Bit CKDIV8 has to be set to 0. Also make sure that you leave Serial program downloading (SPI) enabled!
Connect the ISP and the power.
Set the FUSE-Bits with avrdude
Reset the controller

Flashing the Image

After compiling the ethersex.hex you can flash it with avrdude. The following commands depend on your ISP-Programmer. This example is for a serial connection (e.g. the ATMEL Evaluation-Board):

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

For a USB-ISP-Programmer this command should be used:

 avrdude -v -p m32 -c stk500v2 -P /dev/ttyACM0 -U flash:w:ethersex.hex

For a parallel ISP-Cable:

 avrdude -p m32 -e -c stk200 -U flash:w:ethersex.hex

Parameters for MyAVR mySmartusb light (the -e is important):

 avrdude -p m32 -e -c stk500v2  -P /dev/ttyUSB0 -U flash:w:ethersex.hex

After flashing remove the ISP-Cable and interrupt the power connection for a short time to reboot the board.

 * -p m32: ATMega32; -p m644: ATMega644
 * -v: display debug messages 
 * -c ponyser: the way avrdude speaks with the Evaluation Board; -c stkk500v2 for the Atmel board
 * -P /dev/tty.serial the serial port your programmer is connected to; -P COM1 for windows machines
 * -U the command you want to execute. In our case we want to flash: -U flash:w:ethersex.hex

Replace ATMega32 with an ATMega644, ATMega644p or ATMega1284p

ATMega644, ATMega644p and ATMega1284p have got a bigger flash then the ATMega32. This gives the possibility to add more modules to your Image.

Swapping the Microcontroller

Disconnect power and ISP-Connector.
Remove the old processor from your board.
Insert the new processor while the slot is at the same position as in the socket.

Differences between ATMega32, ATMega644, ATMega644p and ATMega1284p

Flashing with Windows

There a two main possibilities:

Flash with avrdude
Flash with AVR Studio

Flashing with avrdude

The flashing with avrdude is just like in Linux.

You can get the Windows-Binary as a part of WinAVR

In the command line you have to adjust the name of the serial Ports. (COMx instead of /dev/ttyxx)

avrdude -v -p m32 -c ponyser -P com3 -U flash:w:ethersex.hex

If the programmer is connected via USB you need:

for real USB-Programmers: libusb0.dll (Part of WinAVR)
USB-to-Serial Converter a matching Driver: [1]

Flashing with AVR Studio

AVR Studio from Atmel offers a GUI to Controll the ISPs.

AVR Studio also brings USB-Drivers for the Programmers with it, which can be installed together with it.

For USB-to-Serial converters you need a matching Driver: [2]
