Hello, I have received your schematic.
I think what cap you mentioned in " leaving out a cap " is C3, so as you know, we should set GPIO0 at high before chip is enbaled, now cap at GPIO0 slows down the rising of high level, we could only decrease the enable speed.
Anyway, I think removing C3 is better.

Hello, I have exactly the same problem with my custom board. All features are ok, but the board doesn’t start without a press on the EN Button.
I’ve started a topic on this problem on june with my schematic and I’ve checked all the pins.
Any help will be appreciated. The link on my initial post is :

Thank you in advance.
