I have problem with programming standalone ATMEGA2560 in my project via FT231X over ARDUINO IDE.
First of all, I loaded bootloader throught Arduino UNO R3 as ISP over JTAG to my ATMEGA2560. This procedure going well. However, problem is, when I want to compile some code in ARDUINO IDE and burn this code into my ATMEGA2560 over USB serial converter FT231X. In ARDUINO IDE shows errors with timeouts. Can you look on my wiring diagram and tell me, if there is some problem in wiring or elsewhere?
Thank you very much for any help
