<![CDATA[ESP8266-01 auto reset with FT231XS not working]]>I created a new design using the FT231XS chip that has RTS and DTR pins to allow me to program an ESP8266-01 module without holding down a button and powering it up. The two NPN transistors used in other designs should take care of things.

Right now in the Arduino IDE things look fine.
-power is going where it should
-the FTDI com port appears
-programming leds blink for a second but the sketch will not upload

Can someone take a look at the attached schematic to see if anything obvious was left out? I'll poke around with the oscilloscope over the next few days to find the problem.

Nice to see old OLED board creator there 😉

Your schematic looks good, at which speed did you tried to upload ? Did you programmed the FTDI chip with FT_PROG to see pin setup and functions ?
