ESP12e barebones - can't upload
Posted: Mon Apr 24, 2017 12:27 pmHi- I'm trying to flash a sketch using Arduino IDE onto a standalone 12e board. Everything works on my NodeMCU dev board, but I cannot get the standalone to accept the program. Keep getting:
warning: espcomm_sync failed
error: espcomm_open failed
I'm connected by an FTD 1232 board to the Rx/Tx/Gnd pins shown in the attached schematic. I've got the Arduino IDE set to 115200 baud and a generic ESP8266 module. When I go to upload, I hold down the switch that pulls GPIO0 low, plug in, and release switch. I've also tried to hold the switch down, no effect.
I looked around and saw that GPIO15 is supposed to be low too, so I used a microclip to pull that down since it's not on my PCB, and that doesn't work either.
What am I missing? Thanks!
