Dear All We have a little program written by C#. It will read data from ttyS1 and show information on X-window ( lightdm). We write the autorun to start the program whenever Nano PI M1 starts. The problem is the program can't show anything when it is brought by autorun. But when we kill the program and restart by hand, everything is fine. Could you give me any idea to solve this problem. ThankS!
I would suggest using PSU-ONECOM or some other UART adapter and minicom to view your boot messages. Maybe describe how you do autorun. This is probably at the end of the boot process.
Thanks! The autorun is in the directory fa. the full path is /home/fa/.config/lxsession/LXDE/autorun it will bring program up when LXDE is ready. As I said before, the ttyS1 communication is no problem when we restart this program . Please help. Thanks!
So, the boot messages don't tell you what is happening? Maybe look in syslog to see if you can see any differences. I can't suggest anything else. Good luck!
