I have rescued 3 nodes now from bricked status but just got a new one that does not respond. I wonder if they have changed something again.
The node is a new Bullet M2 Titanium
The symptom is that I can get no output from the serial port. So I can't command the urescue.
Holding down the reset at power-up for 10 seconds or so will put it into the TFTP loop and it will respond to a ping and accept a 5.6 load (but not a 5.5).
After the load, it still won't respond. I assume because it still has the bad boot loader. (Someone loaded AREDN without downgrading to 5.5)
Anybody else see this?
The serial device is OK. It echos back if I connect TXD and RXD.
Tried everything I can think of, but no joy.

- Put a scope on the the txd of the board and get nothing
- Seems that the serial port is dead
- Txd is not shorted, btw
