Firmware upgrade fails

Hi!

I've use the instructions from http://wiki.openenergymonitor.org/index.php?title=RFM12Pi_V2#Upgrading_RFM12Pi_Firmware_Direct_from_the_Pi to upgrade the firmware, but it doesn't work.

avrdude -v -c arduino -p ATMEGA328P -P /dev/ttyAMA0 -b 38400 -U flash:w:RF12_Demo_atmega328.cpp.hex

What can be wrong?

Bump - The same is happening for me.

See "avrdude-original: Using autoreset DTR on GPIO Pin 7" it may apply. Depending on when your autoreset script was installed it maybe a 0.12s or 0.3s (or maybe 0.32s) pulse, since you are using avrdude 6.1 it should be 0.3s, you can edit it manually at /usr/bin/autoreset changing the line "time.sleep(0.12)" to "time.sleep(0.3)".
