[systemd-devel] How to print debug printf messages when we login using telnet

[Dhananjay Patil]

Dear All,
We successfully login using telnet on board.
Our application start as systemd service in order to start at boot time.
We define service as follow:
[Unit]
Description=Initmyapplication

[Service]
ExecStart=/usr/bin/myapplication &
Our application have some debug messages implemented using printf.
After completing login process using telnet those printf are not visible on telnet.
After killing application by kill -9 myapplication command and starting application by executing command /usr/bin/myapplication & debug printf are visible.
I have following question

  1.  How to get those printf when AM4376 start after power on and available on console when we login through telnet?

I tried Standard output =tty

            TTYPATH= /dev/pts/0

But if there is no device (/dev/pts/0) service gets terminated
      2. Is there any other way to print debug printf output when we login using telnet?

Please guide me to solve the issue.

Regards,
Dhananjay Patil
