Error after booting RRSDK kernel

Error after booting RRSDK kernel

This question is not answered

Hi I was able to install RR SDK for my DM365 (DM355SDK840402) Leopard board successfully. After booting is completed I am getting an error saying

"can't open /dev/ttyS0: No such file or directory process '-/bin/sh' (pid 326) exited. Scheduling for restart" .

Can anyone please help me to sort this out. 

Thanks

  • Please turn off your board, turn it back on again, and paste all the output from power-on until you can't open /dev/ttyS0.

    Key items to look at are kernel command line being used and anything in the kernel boot that mentions console.

    Thanks for the reply Todd Fischer :).  I have attached file containing DM355 environment settings and its boot log. Also I tried booting Ubuntu file system built using rootstock via NFS. But even that doesn't work :( . It hangs at " STARTING GNOME DISPLAY MANAGER" . I am trying to bring up UI, can you please give me pointer on this?

    I tried booting board with same file system mounted via NFS, for this case the problem was different.
    Configuration of network interfaces fails :(. I have attached the log of the same.

    Thanks

  • Hi Cristina ,

    While I was anticipating for your reply, I tried following things

     

    1. When file system was mounted via NFS, I was getting network configuration error, I modified /etc/network/interfaces and this did the trick. I will get a message saying

    "Press Enter to activate the console". But no display on device connected to video output

     

    2. I used to 2 GB SD card , to mount the same file system. In this case I got a video output on my screen which  shows Ridge Run LOGO.

    But when I try to run one of the examples from /usr/local/media

    I get the following error

    Now playing: hello
    Running...
    Error: Resource not found.
    Returned, stopping playback
    Deleting pipeline

    Can you please help me to fix this.

    Thanks

  • What is the URL of the instructions you are following?  What did you do before running the example and exactly how did you run the example?  Please paste more output so we can help you.

    My best guess is you didn't run loadmodules.sh
