I suffer from a bad case of random misfiring synapses!

- Sat Sep 12, 2015 4:39 pm #28939 Are you placing GPIO0 to GND while doing a reset or power up ?
Also, GPIO2 and CH_PD need to be pulled-up, while GPIO15 need to be pulled-down.

Im using this diagram


Is this the problem because it show GPIO0 as high and not low?
