Arduino Nano with FT232RL

[s-fr]

Hey Guys.

I built a Arduino Nano Board but instead of a CH340 i built a FT232RL on it, and I was wondering if someone of you could make a quick review of my schematic.

The troubles I have with it, is that it's recognized by the PC as FTDI Device it gets a COM Port, I was able to burn the bootloader onto the Atmega328P. But I'm not able to upload any sketch to it as it say:

         System wide configuration file is "C:\Users\Arduino\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino17/etc/avrdude.conf"

         Using Port                    : COM10
         Using Programmer              : arduino
         Overriding Baud Rate          : 115200
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xca

So the question I also have is, can I use a FT232RL out of the box or do I have to program it first, I know it can be programmed with a tool named ftprog.

Your topic was MOVED to its current forum category which is more appropriate than the original as it has nothing to do with Installation and Troubleshooting of the IDE

On the Arduino board with the CH340, the DTR pin is used to trigger a reset when a serial connection is made which causes the MCU to restart and the bootloader to run. The bootloader, in turn, first checks for an attempt to upload code and then runs the program. Try connecting the pin marked DTR on your FT232RL via a 0.1uF capacitor to RST. The value of the capacitor is not too critical so a 0.22 or 0.47 should also work.

Thats exactly what I did, but It doesn't work at all

Can anybody say if my schematic is correct?
