Ch340 driver

Posted by3 years ago

I just received a signed driver by Winchiphead for their USB Serial bridge CH340. Now it should be possible to use Arduino’s equipped with that without any problems under Mac OS 10.9 to mac OS 10.13 (High Sierra).

Hey guys,

I just bought an Arduino Uno Clone with CH340 serial chip, just to realize the few dollars I saved are not worth. The problem is that I cannot upload the Blink program to the board and I have no idea why. This is what is happening:

Choosing the Board = Uno and Port = COM3, I connect the USB cable and the L LED is blinking and the ON LED is on. So I am trying to change this delay of the blinking with the Blink program example. But when I hit Upload, it takes around 1min and I get this error:

avrdude: stk500_recv(): programmer is not responding

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x1d

avrdude: stk500_recv(): programmer is not responding

avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x1d

until 10. The LED keeps blinking as before and not as I tried to. Since yesterday I was reading a lot of blogs about people that had this issue and this is what I've tried:

Avrdude Usb Serial Ch340 Driver

  • Downloaded the CH340 drives with success and my Windows 10 recognizes it on the Device Manager as USB-SERIAL CH340 (COM3). Same results.

  • Followed this tutorial by babydickonboard to add a new board on the boards.txt. I can use this new board but it still give me the same error.

  • Changed the Programmer to all the options but they were all not working. I'm currently using the AVRISP mkll

  • Uninstalled the IDE version from 1.6.7 and installed the 1.6.3, but same issue happening.

Now I'm out of options. Does anyone have some ideas how I can fix that?
