esphome with esp32s3 UART not work

[fantasiataiwan]

Hi sir

I tried to use faikin to flash the ESPHome firmware, but UART looked not work.
Faikin's GPIO tx/rx is 48/34

ESPHome yaml:

I'm not sure what type of failure you're experiencing, and reading your config without being wrapped in a code block is challenging. I'd suggest getting basic UART working without this component first. See the Debugging heading on the ESPHome UART bus page.
