I can't configure rx-tx ports, how to start an Arduino clone?

Question

Arduino

I bought a fork of Arduino, there is a programmer for it . The drivers are installed, the device is located, but the LEDs on rx-tx are silent, and the test program is not loaded, the IDE writes:

Using Port                    : /dev/tty.usbserial-AH02JYIS
         Using Programmer              : arduino
         Overriding Baud Rate          : 115200

avrdude done.  Thank you.

The pinout when connected looks something like this:

Iteduino    Foca
DTR           DTR
Gnd           Gnd
TXD           RXD
RXD           TXD
З,ЗV         VCCIO

There are two unused contacts on the controller, I don’t know why. The programmer is set to 3.3 volts, like the arduino. But rx-tx are silent, I can't do anything. The board has its own power, the miniUSB cable is suitable, what could be the jamb? Maybe someone will point a noob in the right direction with:

Answer 1

Everything, we decided, we just had to connect to it as an Arduino Micro 328p, and not Uno.

Answer 2

1) Is power being supplied to the controller? Not on the board, but on the chip itself. Can be measured directly on the legs of the atmega or on the capacitors nearby.
2) If the bootloader is not flashed into the atmega, nothing will be uploaded via UART. Try connecting via ISP (6-pin connector).

Answer 3

Your board has its own power, it does not need to be supplied with 3.3 V from the programmer, remove the wire
3, 3V VCCIO
6, 7 output on the SIP7-FW connector are free, do not think about them.

Answer 4

If you didn’t mess up with the power supply (usually at least 1 LED on the board should light up), then immediately after the start of the firmware (after compilation) you need to press Reset on the board, then it will go into firmware mode for a couple of seconds, if it didn’t work the first time scary, I got used to it 10 times
