I managed to get the TC circuit working on my 1st v4.2.4 board, but now I'm unable to update the ATmega chip. The system runs fine and I can make config changes, I just can't update the firmware. I've tried 2 different ATmega328 chips and get the same results.
echo -e "\\n/config\\n" > /dev/ttyAMA0 returns nothing
cat /dev/ttyAMA0 returns 4 x $HMSU lines followed by 1 x $HMAR line
lmclient LMDC,0 returns OK
avrupdate returns:
Stopping LinkMeter OK
LinkMeter platform is BCM2708
AVR fuses ERROR
Starting LinkMeter OK
On the J8 pads I have:
RST: 0v ( this will momentarily show 0.08v when running avrupdate )
TX: 3.3v
RX: 3.44v
