Thank you very much!

@György-Farkas
Thank you.
Can you answer the second and third questions?

When I entered the command omega2-ctrl gpiomux get, I seen it:

Group i2c - [i2c] gpio
Group uart0 - [uart] gpio
Group uart1 - [uart] gpio pwm01
Group uart2 - [uart] gpio pwm23
Group pwm0 - pwm [gpio]
Group pwm1 - pwm [gpio]
Group refclk - refclk [gpio]
Group spi_s - spi_s [gpio] pwm01_uart2
Group spi_cs1 - [spi_cs1] gpio refclk
Group i2s - i2s [gpio] pcm
Group ephy - [ephy] gpio
Group wled - wled [gpio]

I have several question about Omega-2+ pins.

1. Omega 2+ has three UART? I know about UART0 and UART1, but what pins support UART2?
2. What pins support PWM and how to use them? (Is it possible to connect the servo motor?)
3. What is it Group refclk, Group ephy and Group wled?

@William-Scott
Thank you

How to cancel the automatic time synchronization with the server on Omega2?

@György-Farkas
Thank you

When I enter echo '123' >> /tmp/mounts/SD-P1/data-$(date +%d.%m.%y-%H:%M:%s).csv
Omega2 write -ash: can't create /tmp/mounts/SD-P1/data-27.12.18-16:49:1545929397.csv: Invalid argument
When I enter echo '123' >> /root/data-$(date +%d.%m.%y-%H:%M:%s)
All working

@cas
Thank you. I added the line with deviсe key to the file /.ssh/_known_hosts and it all worked.

@cas
Thank. I realized that the my program on Python is working. I have another problem:
I want that when you start Omega, the file is sent to another computer via psync. I entred the command rsync -e "ssh -i /root/.ssh/id_rsa" /tmp/mounts/SD-P1/data.dat user@192.168.0.19:/home/user/Desktop to the file rc.local. It would seem that everything should be in order, but the log shows it: Host '192.168.0.19' is not in the trusted hosts file.
Do you want to continue connecting? (y/n).
At the same time, if i enter this command manually, then everything works. I think that by the time the command start, the file with the saved networks is not loaded yet and for this Omega asks for confirmation. How to fix this?

@cas
Are there ways to run scripts automatically when Omega is fully loaded?
