Brad _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joshua Hintze Sent: Wednesday, December 03, 2008 3:17 PM To: Ring, Chris; [email protected] Subject: RE: system() and Codec Engine Thank you Chris, that is very helpful. Especially the wiki "what to use with what" link. One last thing I've never been sure of is how do you update cgtools? The guy who setup this machine that I am using is long gone from our company so I never saw where it originally came from. I'm guessing the DVSDK cd we got. I'm curious if you can download later versions from TI through myTI account or something. I did however run across this site: https://www-a.ti.com/downloads/sds_support/targetcontent/LinuxDspTools/downl oad.html The only thing that makes me a little suspicious is that all the download links list eval on the file names. I also don't know if you can use these commercially then. Any ideas?

(CE 2.20 is OMAP devices only, and CE 2.21 will require an update to a newer gcc toolchain).

Just going to the updates website at: http://www.ti.com/dvevmupdates I see the latest DVSDK is 1.30.01.04. Inside this the release notes say that it is bundled with dsplink_140-05p1. Is there a different download site for the latest codec engine utilities and such?

I think one of the Link releases had an issue when the apps used system() calls. [ I want to say it was fixed in Link 1.50. ] Chris _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joshua Hintze Sent: Monday, December 01, 2008 4:55 PM To: [email protected] Subject: system() and Codec Engine Hey guys, I'm having a problem when using a system() C function call and the codec engine is running. I know inside a POSIX system(.) it essentially forks, execs, waitpid. From what I read a child process is spawned with the parent's copy of a data space, heap, and a stack. Anyways when I call the system function WITHOUT the codec engine running it executes properly. Just for a test I do something very simple: system("date > test.txt"); Now when I run that with the codec engine running in a separate thread, I get a kernel Oops Error and when the program goes to exit it freezes the davinci. Unable to handle kernel paging request at virtual address c4e06c8e pgd = c06bc000 Any thoughts? Thanks, Josh
