  • Hello,

    It looks like I got the same problem. Following the instructions given by Advantech from a PDF file ("DSPC-8661 Demo Quick Start Guide 0.3.pdf") found on the Linux Live they give as a downloadable disc image (from http://support.advantech.com/Support/DownloadSRDetail_New.aspx?SR_ID=1-O4X0N7&Doc_Source=Download, i get stuck at the point where i have to execute a script, video.sh. I do it from the ~/src/ti816x_pcie directory, and i get the following output :

    ubuntu@ubuntu:~/src/ti816x_pcie$ sudo ~/Desktop/video.sh
