Installation: Disk 2? (DM365 EVM)

Ken Koller

Hi,

I downloaded several files from a link that now seems to be working (it was broken this weekend). The wiki pages for the software installation talk about installing some A/V files from disk 2 but I have no disk 2. It also suggests that the file may be downloaded but I do not them listed in the link.

Any ideas?

Thanks,

Ken

Installing the A/V Demo Files

Disk 2 contains the A/V files used by the demos. After following the instructions in the previous section, follow these instructions to install the A/V files:

1) Go to the "clips" subdirectory of the DVSDK directory that you set up previously. For example:

host $ cd ~/dvsdk_#_#/clips

2) Insert disk 2 and Ubuntu will automatically mount it for you in /media/cdrom0. Copy the data.tar.gz file from the mount directory to the clips directory. Alternatively download the appropriate A/V files package for your particular EVM and copy it to the clips directory. For example:

host $ cp /media/cdrom0/data.tar.gz ./

3) Extract the A/V data files. For example:

host $ tar -zxvf data.tar.gz

Sorry about that, I am not sure why the clips are not up there on the DM365 DVSDK page, this is something I will have to check on internally. In the mean time you do not really need them for real development on the DVSDK, or even for exercising the demo as long as you have a video source to feed into the DM365 which you can use to record your own a/v files.The best I can offer for now are the DM355 a/v files which should at least give you an MPEG4 file you can decode, though you may have to use the command line demo to run it.

It looks like I can do one better, there are actual video files up there they are just not sorted in the same way as the GSG was expecting, there is a flash restore image on the DVSDK 2.10 download site that contains these media files. It is a tar file of the intended out of the box filesystem for the DM365 EVM which happens to have the media files in it under opt\dvsdk\dm365\data. I am not sure why the actual data.tar.gz is not listed, as it is for other device's DVSDKs, if it looks like there is no plan to have it out there I can update the GSG to reflect that.

Final update, data.tar.gz has been added to the download site.

Hi Bernie,

I am new to Ti and Linux and I need some help.

I really like what I have seen and read so far about the DM365 and I would like to use it in a video survielance project. However, there are some questions I need answered:

1.) My intended host system is a PC running XP home edition, do you think i should partition my drive and install linux?

2.) if I should use Linux for development on my host, which distro. is currently stable for a PC?

3.) Montavista wants a lot of money for the pro version of their OS.... their price is wayyyyyy out of my range; how stable is the demo version that comes with the DM365 EVM kit,? and from an E 2 E , would you recommand releasing a survielance product based on the Montavista demo version that ships with your EVM?

4.) Finally, do you know anyone besides Leopardboard.org that has a cheaper CMOS sensor for the DM365 EVM?

Thanks in Advance

These are all very good questions.

1) Yes, you will likley need to use a Linux host. I would probrably recommend using a virtual machine program like VMWare workstation or the free VMware player; then it would be esentially like running an application program within Windows.

2) We have been using RHEL 4 for a while so RHEL 5 (RHEL 4 is no longer selling) would probrably be a good choice. Ubuntu is also a good choice and its free.

3) The demo version we provide is good from a functional and stability perspective; however, we only update TI specific drivers whereas MV updates much more, including general OS fixes. Most likely, you will get everything you need to DM365 develoment from our demo distro; however, this is a real complex decision and we avoid giving advice which borders on the legal realm (e.g. release product based on demo version). I believe you can go to production with the demo version; but will stop short of suggesting you should.

4) Not sure which Leopard board you are referring to, but from a cost perspective, the cheapest sensor board I know of is one build for DM355 ($99) which may be easily adaptable to DM365: http://www.leopardboard.org/

I agree with Juan: Install VMWare and use a virtual machine. My development system is Mac laptop. I run Windows as a guest for most of my embedded tools (usually IAR) and when I began this project I just downloaded Ubuntu and installed it as a guest. It's impressive technology.

A Wiki page exists that will guide you in your Ubuntu installation (as well as for Red Hat).

Best of luck.

VMWare is great, especially if you want to be portable, but if you have an extra machine lying around it can also be handy to have a directly installed Linux box. I do it this way for performance and not having to deal with booting and shutting down the VMWare virtual machine on my Windows laptop, I just VNC into the Linux box from the laptop and it works much like VMWare (or I can just SSH for a terminal, or Samba for files).

Thanks Guys,

I think I'll go the directly installed route, I'll be nice to have a development station for each OS plateform(Linux, VxWorks,uc/os 2 ect..) anyways.

Thanks Again guys, i'll keep you posted on progress.

Juan, I am talking about www.leopardboard.org, they have a Camera mudule that comes with a 2A lib. that they want $299 for. I'lll check out the one you're talking about though.

thanks
