I designed a PCB based on MPU9250 IMU and ESP8266-12F and FT232RL uart-ttl bridge. You can see schematics for the usb to uart, and esp8266 circuits here.
When I researched about the uart part of the circuitry, I see numerous example mentioning FTDI USB modules and esp8266 bare chip programming. Therefore, I build my usb-uart circuit based on FTDI module and used FT232RL. However, I can not be able to program with using Arduino IDE NodeMCU flashing configurations. When I press reset button while holding gpio0 button I see following from serial port. I thought esp goes boot mode however I can not be able to communicate or upload the code. I want to ask what should I do in order to communicate with esp and upload firmware? I know I can not be able to provide enough information, however I am willing to share more if you ask.
This is what I get when I upload the code. It says "chosen serial port can not be found in attached board" and timed out when waiting for packet header
