I have some problems when uploading the sketch,
Arduino:1.8.12 (Windows Store 1.8.33.0) (Windows 10), Tarjeta:”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 : 237708 – code in flash (default or ICACHE_FLASH_ATTR)

IRAM : 26928 / 32768 – code in IRAM (ICACHE_RAM_ATTR, ISRs…)

DATA : 1252 ) – initialized variables (global, static) in RAM/HEAP

RODATA : 828 ) / 81920 – constants (global, static) in RAM/HEAP

BSS : 25000 ) – zeroed variables (global, static) in RAM/HEAP

El Sketch usa 266716 bytes (27%) del espacio de almacenamiento de programa. El máximo es 958448 bytes.
Las variables Globales usan 27080 bytes (33%) de la memoria dinámica, dejando 54840 bytes para las variables locales. El máximo es 81920 bytes.

URL´s Correct
Board Installed and updated
Libraries Installed and updated
COM correct
I used a usb based on CH340, another usb /TTL, Arduino UNO.
Nothing work with two board ESP8266 -01 (ESP-01)
I need Help.
 
Thank you so much
