I have problem, that there is not "ready" after start. I have only in 74880bps:

SDK ver: 2.1.0(ace2d95) compiled @ Oct 24 2017 12:04:16

I have IO0 in high state (also tried in float)
Everything was worked to moment when i sended to device:
"AT+UART_DEF=57600,8,1,0,3" so i turned on flow control.

Anybody have idea what is wrong?
What for is IO15? should it be in low or high state? (i tried both but program doesn't started).

The fact that you see the SDK and phy library versions means you have made it into user program space.

The command you sent dropped the baud rate to 57600, so you will need to change the tty speed in order to see more output after that

There is not any more data. with tty on 57600 i see only garbage. Earlier, before changing baudrate (there was 115200) there was "ready" after garbage.

I found the reason.
I had high state on CTS (IO13) and after turning on flow control it stopped transmision.
