building application

[MuhammadOmarFar]

hey, i have a task to write a helo world program at I.MX 53 quick start board with linux operating system using eclipse SDK. i am a student and doing my internship. can any one guide me ? or tell me any document which tells the procedure step by step.

Thanks

actually my project is to build application for image processing using openCV. i think it will be better to write code on host and then run the binary on target. i am afraid have little knowledge about tftpboot , NFS etc , but still i am setting up the host and target by acting upon the instructions that are mentioned in documentation without knowing whats the meaning of these commands :)

i have built and install LTIB , the next step is to run image on target board. the instruction for it are so complex that i am confused.. do you know any other document where they explain it in more detail.

thanks

Any application can be built on the host and run on the target, that's how most developers - with respect to QSB - work. But a few build and run on the target. If you decide to build on the host, look into tftpboot the kernel and NFS mounting your rootfs, saves you from having to burn a card every time you make a change. But if you are building only applications or scripts, building on the target is fine, just make sure you back up regularly. :)

Note - application developing is done on host machine, and relatively simple applications
(as "Hello World") may be build on host and then run on the target demo image.

ok. thanks

I know a customer who was booting into Ubuntu on the QSB and building there, it's Linux and Ubuntu, so connect it to a network to install any necessary packages ( sudo apt-get install pkg_name ) or use the Ubuntu package manager. You should be able to do builds, etc.

ok i will check for it.i want to know that can i build an application directly on imx platform ? i read the document which tells how to build application on host computer and then compile it to run on imx board. is the host computer necessary ?

[RandyKrakora]

If you download the BSP docs, it has a guide on how to setup the BSP and run ltib.

Also, for some extra VM and ltib setup you can look around here: http://www.imxdev.org/wiki/index.php?title=All_Boards_LTIB

thanks Yuri . this document tells how to setup eclipse SDK but i am afraid i don't even have BSP running on IMX platform. can you tell me any document from where i can start building LTIB  and install linux on my IMX platform. 

i put a linux image in memory card and then run IMX board and it works fine. can't i use image ?

Here's a start:

The eclipse section is not complete, but shouldn't be too difficult to finish.
