Can't upload via FTDI

Hello!

I tried to upload to the ESP8266 Thing via the FTDI Adapter FT232RL.
The FTDI jumper was put to 3.3v. I was a bit unsure on how to connect the pins:

Left is FTDI and right is ESP8266 Thing.
DTR -> DTR
CTS -> NC
VCC -> 3V3
TX -> RXI
RX -> TXI

Default code from the Hookup-guide: https://learn.sparkfun.com/tutorials/esp8266-thing-hookup-guide
Code: Select all#define ESP8266_LED 5

void setup()
{
  pinMode(ESP8266_LED, OUTPUT);
}

void loop()
{
  digitalWrite(ESP8266_LED, HIGH);
  delay(500);
  digitalWrite(ESP8266_LED, LOW);
  delay(500);
}


Board-Manager-URL: http://arduino.esp8266.com/stable/packa ... index.json
Board: SparkFun ESP8266-Thing (tried the generic one too)
CPU Frequency: 80 MHz

Error:
warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed


The FTDI blinks after pressing Upload, as if it actually tries uploading.
Both are connected to my Computer.

I suspect wrong wiring of mine, as I'm quite a beginner.

Thanks for taking your time to read my thread, would be happy for every bit of help <3
