Problem Description

i connect TX ESP-01 to arduino uno TX and RX to RX, when upload code i connect GPIO0 to GND and after uploading remove it, when open serial monitor it open loop of reconnecting . the result :

You're cycling through forbidden pins. I'm pretty sure some of the pins you're trying to use are used for flash access.
Closing due to user error.
