Error uploading to ESP-03 8266

Hello everyone. I'm trying to uplaod code to my ESP-03, with these settings: Generic ESP8266 Module, CPU frequency: 80MHz Flash Frequency: 40MHZ Flash Mode: DIO baud rate: 115200 Flash size: 4M(1M SPIFFS) Reset Method: ck

Wiring VCC - 3.3V GND - GND CH_PD - TXD - TX (computer) RXD - RX (computer) GPIO2 -

does anyone have advice? thank you - Iacopo

Google for instructions on how to upload a sketch to an esp. Your connections are incorrect.

Hi. Thanks for that, but I do believe my ESP may be damaged or even broken.. Ive followed the connections and nothing is working

Like PaulRB said, the connections you've tried are wrong.

You can't have two devices transmitting on the same line. Device one should transmit to the receiver line of device two, and device two should transmit to the receive line of device one.

You didn't enable the chip, either. CH_PD shouldn't be floating.

As far as I know, there aren't any 4MB versions of the ESP-03, only 0.5MB. You probably want to use QIO mode instead of DIO.

What reset circuitry are you using? Did you tie GPIO0 to ground manually while resetting/uploading?
