![]() The chip doesn't have an Arduino bootloader (new chip) or the bootloader is corrupt/damaged.įrom some of the causes above, I fixed it.There is another circuit connected to the TX RX. ![]() ![]() ![]() When uploading the program, the notification that appears is not responding, such as:Īvrdude: stk500_recv(): programmer is not responding Cause stk500_recv(): programmer is not respondingĪfter some testing and searching for problems, it turns out that this problem occurs because there is no response from the Atmel ATmega328 microcontroller after sending data from the serial. The initial problem is that I can't program Arduino using USB Serial such as FTDI 232 and CH340.
