I built a heatermeter over a year ago. I've used it ~ 6 times without any trouble. Now the screen doesn't display anything. I'm able to get into the OpenWrt configuration page and get the following message:
No Communication
HeaterMeter serial communication can not be established. Configuration requires bidirectional serial operation. Possible causes of failure:
No HeaterMeter board attached
No HeaterMeter (AVR) firmware installed. See AVR Firmware
Incorrect baud rate in /etc/config/lucid
Hardware malfunction
I flashed with the latest firmware successfully:

This was my first time soldering. As I mentioned, everything was working fine for a year. Any idea what may be wrong?
