Now clicking on HELP (in the setup.exe window) shows the following text: Setup program overviewġ. I tried with ATmega 328P and with ATmega 328P (old bootloader). Try to upload a sketch, same problem as described above. Then clicking INSTALL, and "The drive is successfully Pre-installed in advance" was confirmed. Then I downloaded CH341SER.ZIP, extracted the files to my programs folder ".\arduino-1.8.13\drivers\CH341" and ran SETUP.EXE which also was contained in the zip file.Īt first clicking UNISTALL, driver uninstall was confirmed: hi, what's that, the driver was installed? there was no reaction at all, no window popping up, etc. Therefore I downloaded at first CH341SER.EXE and ran it without success, i.e. And there are tips to install the CH340 driver. In the forum here there are many postings reporting this type of error. Īvrdude: stk500_recv(): programmer is not respondingĪvrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x92 Trying to upload a sketch ends with messages.
The first which worried me was that for selection of a port only COM1 was available.
I am not sure but I believe the problem exists since "new boards available" had been poped up and I installed new boards version 1.8.3 for AVR boards. After years of successfully working with my Arduino Nano with CH340 chip, now it is not possible to upload any sketch.
