CH340G Uploading problem

Question

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

Schematics

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

• Majenko: Have you installed the bootloader?
• ahmetertem: Yes @Majenko, I've burned bootloader and uploaded code via ISP. I can communicate with it already, but can not upload code via USB
• KIIV: What else is on the RESET line?
• DataFiddler: If you can use the CH340 as a Serial-USB bridge (Serial.print and Serial.read work) but you cannot upload a sketch without using a programmer, the bootloader (or fuses) are bad for some reason.
• ahmetertem: @KIIV, 10k resistor like Uno and Nano (5V and reset signals)

Answer 1

The schematic is totally working. My mistake was after burning bootloader, I was uploading code via ISP. If you upload code via ISP, you're removing bootloader.

Thank you everyone who helped me to I wasn't mistaken at schematic and else...
