Hi everyone,

I just received my RFM12Pi v2 daughterboard and I've started playing with it.

Ultimately I would like to be able to communication with La Cross Technology IT+ sensors, so I'm preparing to modify the Arduino code running on the board.

I've followed the directions here first: http://wiki.openenergymonitor.org/index.php?title=RFM12Pi_V2#Upgrading_RFM12Pi_Firmware_Direct_from_the_Pi so that I can validate the way I upload Arduino code to the board, but it's not working :-(

Here is the output of the flash command:

root@rpi:/home/alexandre/weather/RFM2Pi/firmware/RF12_Demo_atmega328# avrdude -v  -c arduino -p ATMEGA328P -P /dev/ttyAMA0 -b 38400 -U flash:w:RF12_Demo_atmega328.cpp.hex

After that my Raspberry becomes unresponsive and I have to reboot it to regain access. I've also tried to interact with the board through serial port via a little Python script but I did not get some convincing results, except turning on and off the activity LED...

Am I missing something here?

Thanks.
