ESP8266 01 can't upload code

Hey guys,
I’m new in this and trying to upload code to my esp8266-01 and I get this error:

Arduino: 1.8.13 (Windows 10), Board: “Generic ESP8266 Module, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), dtr (aka nodemcu), 26 MHz, 40MHz, DOUT (compatible), 1MB (FS:64KB OTA:~470KB), 2, nonos-sdk 2.2.1+100 (190703), v2 Lower Memory, Disabled, None, Only Sketch, 115200”

Executable segment sizes:

IROM : 228624 - code in flash (default or ICACHE_FLASH_ATTR)

IRAM : 26756 / 32768 - code in IRAM (ICACHE_RAM_ATTR, ISRs…)

DATA : 1248 ) - initialized variables (global, static) in RAM/HEAP

RODATA : 688 ) / 81920 - constants (global, static) in RAM/HEAP

BSS : 24880 ) - zeroed variables (global, static) in RAM/HEAP

Sketch uses 257316 bytes (26%) of program storage space. Maximum is 958448 bytes.

Global variables use 26816 bytes (32%) of dynamic memory, leaving 55104 bytes for local variables. Maximum is 81920 bytes.

This report would have more information with

option enabled in File → Preferences.

Maybe someone knows how to fix this issue? I’m using a USB ESP8266 adapter to upload code.
