| − | = Flash AVR Net-IO with "ATMEL Evaluations-Board" made by Pollin= | + | = Requirements = |
| | | | |
| − | As a beginner it's difficult to understand everything in terms of flashing.
| + | * AVR NET-IO |
| − | And it's also difficult to find all information.
| + | * ISP-Programmer (we're using a Evaluation-Board made by Pollin) |
| | + | * 10-pin connector cable (from Evaluation-Board to the NET-IO) |
| | | | |
| − | == What's needed? == | + | = Flashing with avrdude = |
| − | * AVR Net-IO
| |
| − | * ATMEL Evaluation-Board
| |
| − | * a 1 on 1 Cable for the [[ISP]]-Port (10-pin Connector).
| |
| | | | |
| − | === Other ISP Programmers ===
| + | Avrdude offers several options. We will look on the most important, to make basic flashing of ethersex possible. |
| | | | |
| − | If you have a ISP-Programmer with 6-pin port you can create an adaptor. You can see the pin configuration in figure 4-1 at page 5 [http://www.atmel.com/dyn/resources/prod_documents/doc2521.pdf AVR042: AVR Hardware Design Considerations].
| + | * 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 |
| | | | |
| − | 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)
| + | After you checked all options and adjusted them to your settings you should have a command like this: |
| | | | |
| − | == Flashing with Linux ==
| + | avrdude -v -p m32 -c ponyser -P /dev/ttyS0 -U flash:w:ethersex.hex |
| − | *Connect the 10-pin Cable to the ISP-Connector.
| |
| − | *Plug in the power adaptor of the AVR Net-IO.
| |
| − | *If everything is connected right, the yellow LED of the Evaluation-Board is shining.
| |
| | | | |
| − | 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:
| + | = Writing the Bytes = |
| | | | |
| − | avrdude -v -p m32 -c ponyser -P /dev/ttyS0 -U flash:w:ethersex.hex | + | * Disconnect the power from the NET-IO |
| − | | + | * Connect your ISP cable to the programmer and the Net-IO |
| − | For a USB-ISP-Programmer this command should be used:
| + | * Reconnect the power and connect your programmer to the PC |
| − | | + | * Execute the command you assembled earlier |
| − | avrdude -v -p m32 -c stk500v2 -P /dev/ttyACM0 -U flash:w:ethersex.hex
| + | * 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 |
| − | For a parallel ISP-Cable:
| + | * Reconnect the power, your Net-IO should boot up with ethersex |
| − | | |
| − | avrdude -p m32 -e -c stk200 -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 | |
| − | | |
| − | In some cases you have to set the FUSE Bits, which is possible with this command:
| |
| − | | |
| − | * -U lfuse:w:0xCF:m -U hfuse:w:0xDC:m | |
| − | | |
| − | To get the correct FUSE-Settings you should visit http://www.engbedded.com/fusecalc/
| |
| − | | |
| − | Parameters for MyAVR mySmartusb light (the -e is important):
| |
| − | avrdude -p m32 -e -c stk500v2 -P /dev/ttyUSB0 -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.
| |
| − | | |
| − | === Setting the FUSE-Bits ===
| |
| − | * Reconnect the ISP and the power. | |
| − | * Set the FUSE-Bits.
| |
| − | * '''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.
| |
| − | | |
| − | | |
| − | * (taken from dinus) The ATMega has a clock speed of 1 MHz, no JTAG.
| |
| − | avrdude -p m644 -c ponyser -P /dev/ttyS0 -U lfuse:w:0xE7:m -U hfuse:w:0xDC:m -U efuse:w:0xFF:m
| |
| − | | |
| − | Fuse-Bits from "DiDi". JTAG is turned ON.
| |
| − | | |
| − | * -U lfuse:w:0xf7:m -U hfuse:w:0x99:m -U efuse:w:0xfc:m
| |
| − | | |
| − | Fuse-Bits from "loddel". JTAG is turned OFF.
| |
| − | | |
| − | * -U lfuse:w:0xf7:m -U hfuse:w:0xd9:m -U efuse:w:0xff:m
| |
| − | * -U lfuse:w:0xe7:m -U hfuse:w:0xd9:m -U efuse:w:0xff:m
| |
| − | | |
| − | Fuse-Bits from "Gregor". "The 644 runs at 16 MHz Quartz and is not divided by 8." JTAG is turned ON.
| |
| − | | |
| − | * -U lfuse:w:0xef:m -U hfuse:w:0x99:m -U efuse:w:0xff:m
| |
| − | | |
| − | === flash Ethersex ===
| |
| − | * change Config of Ethersex (make menuconfig) to ATMega644 and build (make)
| |
| − | * flash with
| |
| − | avrdude -p m644 -c ponyser -P /dev/ttyS0 -U flash:w:ethersex.hex -v

| − | == Flashing with Windows ==
| |
| − | There a two main possibilities:
| |
| − | #Flash with avrdude
| |
| − | #Flash with AVR Studio
| |
| − | | |
| − | If you don't want to install one of those programs, there is a [[Live CD]] to use.
| |
| − | | |
| − | ===Flashing with avrdude===
| |
| − | The flashing with avrdude is just like in Linux.
| |
| − | | |
| − | You can get the Windows-Binary as a part of [http://sourceforge.net/projects/winavr/ 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: [http://www.ftdichip.com/Drivers/VCP.htm]
| |
| − | | |
| − | ===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: [http://www.ftdichip.com/Drivers/VCP.htm]
| |
| − | | |
| − | == Live-CD ==
| |
| − | You don't have to worry about your System if you use a Live CD to flash your build.
| |
| − | | |
| − | * Download and burn the CD: [http://www.ethersex.de/index.php?title=Live_CD]
| |
| − | * Get the libncurses5 Package: apt-get install libncurses5-dev
| |
| − | * Update and install the software for ethersex just like described here: [http://ethersex.de/index.php/Quick_Start_Guide/Preparation]
| |
| − | * If menuconfig fails try this command: apt-get install dialog
| |
| − | * Flash like described in the "Flashing with Linux" section is described.
