Reset line goes high instantly at power on and stays there.
Put a 22uf from the Reset line to GND and it powers up every time?
The question mark is not why - I know why the 22uf works as I expected it to once I looked at Reset line with a DSO.
The question is - Why is reset not working normally, OR, is reset working as it should and there is another underlying problem at power up that requires a reset to overcome it. I'm tired of chasing my tail.
It's all too hard.
