Hello, i'm having problems with a led blinking code using a Mini D1 ESP32. In short, everytime i try to upload, using my laptop, it gives me this error: ```arduino Sketch uses 236793 bytes (18%) of program storage space. Maximum is 1310720 bytes. Global variables use 21048 bytes (6%) of dynamic memory, leaving 306632 bytes for local variables. Maximum is 327680 bytes. esptool.py v4.5.1 Serial port COM3 Connecting... A serial exception error occurred: Write timeout Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers. For troubleshooting steps visit: https://docs.espressif.com/projects/esptool/en/latest/troubleshooting.html Failed uploading: uploading error: exit status 1 ``` The funny thing is that i tried it on my other PC and it works, so at least i know the problem is not the cable or the board itself. Anything could help. ---
