yes last week i was trying to upload it
as selected board :
1. esp32 dev module got error A fatal error occurred: Timed out waiting for packet header
2. generic esp8266 esp_system.h: No such file or directory.
also ive tried and different boards but with no success
after of many tries i upload the code to 8266 as generic esp8266 module and got that message Warning: Image file at 0x0 is not a valid ESP8266 image, so not changing any flash settings.
reset and i open the serial and nothing .no wifi .
