I made the following schematic, which uses a auto programming circuit similar to the node MCU 0.9 design (see VT1 and VT2 here). Mine is designed to be identical since my board also uses S8050 transistors and 12K resistors. My FTDI is a FT232RL which has both DTR and RTS output on it.
The same FTDI and wires can successfully flash the 8266 if I manually boot it into flash mode, so that narrows down the issue to my implementation of the auto flashing circuit. When I go to flash it using my flashing circuit I get the infamous "Connecting........_____....._____....._____....._____....._____....._____.....____".
What is wrong with my hardware design? I *think* it's related to a missing capacitor C2 in the nodemcu design which mine does not have. I suspect this from reading posts like this and this. What do you think?
