I've tried to copy CH340G from other schematics and existing Arduino Uno Clones... Searched online & StackExchange but no good :/ My problem is almost the same as this one
Here is my schematic
I can read & send data from the serial monitor
- OS: Win 10 64 Bit
- USB Driver: 3.5.2019.1
Upload Options:
- Arduino IDE version: 1.8.12
- Board: Arduino Uno (also tired nano & nano old bootloader options)
What I've tried:
- With & without the driver
- Rebooted the computer
- Tried different ports
- Different cables
- In case of IC not working, I've desoldered IC from working UNO
- Changed RX, TX vice versa
- Without R1 & R2
- Different capacitors on C6 and C3 Buuut results are always the same as below

avrdude done. Thank you.
Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
I appreciate any help, idea, suggestion Regards
