wiki:How_to_flash_the_FSC

Here I try to collect some information about flashing new firmware onto the FSC board. While the FSC has been built to be Arduino-compatible, we never really managed to install the well known Arduino bootloader onto the FSC. So the firmware can't be installed via USB, but needs to be programmed via the ISP port using an external ISP programmer like the one shown in the picture below. This is an original "AVR ISP mkII", but others should work as well.

The AVR ISP mkII on Ubuntu

Check if the USB connection works. Leave the programmer unplugged from the board to be programmed, but connect it to your PC via USB. You should see it, when typing lsusb in a terminal, e.g. like this:

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 007: ID 03eb:2104 Atmel Corp. AVR ISP mkII               <--- this is it.
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

In order to speak to the programmer, the program called avrdude is needed. It can be simply installed by

sudo apt-get install avrdude

We can check, if avrdude can talk to the programmer, even before the programmer is connected to the board, by typing:

avrdude -p m328 -c avrispmkII -P usb -v

Here the -p parameter, specifies the type of the microcontroller (MCU) we want to program, since we actually don't want to program any MCU right now, but just check, if we can talk to the programmer, this parameter doesn't matter. However this parameter is not optional. The -c parameter specifies the type of programmer, we want to use and -P specifies the port, we connnected the programmer to. (Luckily specifying 'usb' is enough and we don't have to specify the bus and device number).

The ouput might look like this:

dneise@NeiseLenovo:~$ avrdude -p m32 -c avrispmkII -P usb -v

The problem here is, that your user does not have access rights for this USB device. We solve this quickly by putting sudo in front of the command. Also we add the -v option in order to get more information

dneise@NeiseLenovo:~$ sudo avrdude -p m32 -c avrispmkII -P usb -v

avrdude done.  Thank you.

As we see, in the end avrdude complains about a missing target. The reason is simply, that we did not yet connect the board. Now let's connect the board. Make sure the connector is plugged the right way around. Pin 1 of the ISP connector on the FSC board is the one farthest away from the MCU. Also make sure the board is powered, since it will not be powered through the programmer. In case all connections are fine and the board is powered your output might look like this:

dneise@NeiseLenovo:~$ sudo avrdude -p m32 -c avrispmkII -P usb

avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.01s

avrdude: Device signature = 0x1e9502

avrdude: safemode: Fuses OK (H:FF, E:D9, L:FE)

avrdude done.  Thank you.

You can even use the programmer in a kind of interactive session, and e.g. ask for the supply voltage level of the board. In order to change into interactive mode, add the -t option (for "terminal" mode). After you're conected to the board, you can ask for some paramters of the target, using the "parms" command. In order to quit, simply type "quit". It might look like this:

dneise@NeiseLenovo:~$ sudo avrdude -p m32 -c avrispmkII -P usb -t

avrdude: AVR device initialized and ready to accept instructions

avrdude> quit

avrdude: safemode: Fuses OK (H:FF, E:D9, L:FE)

avrdude done.  Thank you.

If you accomplished this, you can be sure, that your programmer is nicely connected to the FSC board.

Getting the firmware

For your convenience, you can always find the latest version of the firmware in FACTs SVN repository. https://trac.fact-project.org/browser/firmware/FSC/FSC_firmware_version_from_20140318_1700.hex Simply check out that file.

Flashing the hex-file

In order to tell avrdude to write the hex-file into the MCUs flash memory, we use the -U option in the form:

-U <memtype>:r|w|v:<filename>[:format]:

In our case memtype is "flash", the want to write so we choose "w" next, and then we just give the filename, since the format can be inferred from that. The entire session looks like this.

dneise@NeiseLenovo:~/FSC_firmware_flash$ sudo avrdude -p m32 -c avrispmkII -P usb  -U flash:w:FSC_firmware_version_from_20140318_1700.hex

Congrats, you just flashed the FSC!
