Hello,

I have finished putting together the heatermeter v4.3. I have everything soldered. I can boot up my raspberry pi and I see the web application. When I try to flash the firmware, I get the following error:

Downloading 'https://heatermeter.com/devel/snapshots/trunk/heatermeter.hex'

Starting LinkMeter OK

How do I trouibleshoot this issue?

I've checked voltages for the ATMega for 3.3v at VCC, AVC, ARE, and RST. I am not getting 3.3v, I am getting 1.4v for VCC, AVC, and RST. For ARE, I am getting 0v. I am seeing 12v at the point labeled 12v on the 3 pin regulator.
