Other Parts Discussed in Thread: AM5728

Hi,

We are testing our custom hardware designed with AM5728 with processor SDK.

LCD is displaying  /usr/bin/runWeston: line 39: 692 Segmentation fault weston --idle-time=0 >> /var/log/weston.log 2>&1

The Kernel is hanging with the following messages. Kindly help on this,

    Have you used different UART console port in your custom board ?
    Suppose you have used UART console port 1 then you should change the /etc/initab" file /dev/ttyO1 whereas EVM board might have used "/dev/ttyO2"
    You have to use correct console UART port to get successful login.

    Hi,

    In every post we are mentioning the SDK as well as Hardware. We are creating the multiple threads for multiple problems only. We are doing this to solve the issues as soon as possible as we have lot of pressure . Earlier we had worked on GLSDK. Recently your team requested to change over to Processor SDK. Due to this we required lot of efforts. We will continue this till some time.

    Thanks & Regards,
    N.V.Subbaiah.
