Customer:
I cannot upload to the board since yesterday afternoon. The program compiles correctly but stops during upload and takes a long time (the LED does not blink - it stays off). Eventually I get an error as shown in the error log. It appears the upload cannot reach the selected serial port, even though in Device Manager and the Arduino package the selected port matches and shows as active, and in Properties the port says it’s OK.
I tried a different cable just in case, but it made no difference. I had not changed any configurations before this problem.
I renamed the selected port from COM5 to COM19 and when attempting upload got the error:
avrdude: ser_open(): can’t open device “\..\COM19”: The system cannot find the file specified
I also used Device Manager to uninstall all ghost COMxx ports, restarted the laptop, but with no success.
The driver in use is “Silicon Labs CP210xUSB to UART Bridge”.

Da li bi mi molim Vas mogli pomoći sa sljedećim: Nikako ne mogu napraviti UPLOAD od jučer poslije podne - u prilogu šaljem log datoteke grešaka. Program se korektno kompajlira i onda stane na UPLOAD i to traje poprilično dugo (pripadna LEDica ne trepće - stalno je ugašena). Na kraju mi izbaci grešku kako je navedeno u “Error_log.txt”. Izgleda mi da ne može doći do izabranog serijskog porta iako u “Device Manager-u” i u Arduino paketu se izabrani port i aktivni prikazani (u Device Manager) podudaraju, a u “Properties” port kaže da je OK. Probao sam i drugi kabel za svaki slučaj (makar ne znam zašto bi prethodni krepao), ali nema razlike. Prije ovog problema nisam ništa mijenjao u konfiguracijama. Izabrani port (bio je COM5) sam preimenovao na COM19 i pri pokušaju UPLOADa sa dobio grešku opisanu u “Error_log_2.txt” Ukratko kaže sljedeće: avrdude: ser_open(): can’t open device “\.\COM19”: The system cannot find the file specified Također sam pomoću Device Managera napravio “uninstall” svih COMxx koji su bili GHOST, restartao laptop, ali bez ikakvih uspjeha. Inače koristi se sljedeći driver: “Silicon Labs CP210xUSB to UART Bridge”. Bio bih Vam ekstremno zahvalan na korisnom savjetu za rješenje ovog problema. Najljepša hvala.
