How to build uclinux to DE2 board ,please help!

[Altera_Forum]

hi,everybody, 

I have a DE2 board and I want to install uclinux onto the board as the OS,but I got some difficulties,would you please info me some files or give me some links  that about the whole process of the installation.Including the boarc hardware drives will be better.  Thank you very much.

Thanks for your answer ,I am working on it now,but there&#39;s something that confuse me ,as below:

in step 2 of the wiki, install the PATH of the nios2 gcc.

Thanks so much! It did work.!I&#39;ve made it . And then I have two questions here .. 

1.What should I do if I want to run my own application programme ,that is to say, I wish some programme run just when the system have booted automatically,are there any steps that I must follow? I&#39;ve read of documents on the kernel-start and the system initial , but still I&#39;m a little puzzled .Is the whole  boot and initial process of uclinux same with linux OS? I will be appreciate if you could info me some documents or links.  2. I&#39;ve leaned ARM linux for a short time .But I want to know how to debug my app programme under uclinux ,like under linux,we can debug through TFTP &mount or NFS or zmodern e.g.But how under uclinux,are there any method and develop tools that could help us to cross compile&run&debug in the  application level (not cross-compile on kernel level ),just like arm-linux ,when we finish the kernel ,we can focus on the application development. Thanks a lot .

great! 

 1. see the wiki, http://nioswiki.jot.com/wikihome/operating...nux/uclinuxdist (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/uclinuxdist) <div class='quotetop'>QUOTE </div>  --- Quote Start ---  The simplified "init" program will run etc/rc and etc/inittab during startup. If you want to customize startup, you should update the files vendors/Altera/nios2nommu/ rc and inittab.[/b]  --- Quote End ---    2. yes, you can use tftp, ftp, http or nfs mount to develope apps. there are tftp, wget, and mount (for nfs) in busybox. you can enable them with make menuconfig in uClinux-dist-test . http://nioswiki.jot.com/wikihome/operating...ms/nfsfilesytem (http://nioswiki.jot.com/wikihome/operatingsystems/nfsfilesytem)

Thanks for hippo&#39;s advise,following the" NFSFileSystem "step by step ,when I download the kernel (include busybox->mount, nfs file support ,and default kernel) 

I got a problem as below:  />mount -t nfs -n -o nolock,rsize=1024,wsize=1024 192.168.11.17:/home/mxp/nios2 /mnt/nfs //my server ip  mount :  cannot read /etc/fstab :No such file or directory /etc>ls config default inetd.conf inittab motd rc services version /etc>  however,after a short time ,(I just debug carefully,unkowning why)it becomes:  />mount -t nfs -n -o nolock,rsize=1024,wsize=1024 192.168.11.17:/home/mxp/nios2 /mnt/nfs mount:RPC: Unable to receive ;error = No route to Host mount:nfsmount failed; Bad file descriptor mount:mount on .168.11.17:/home/mxp/nios2 /mnt/nfs failed />busybox mount //it&#39;s okey,but added with the parameters   //it got the same error msg like above.  The sopc Builder sdk shell display like above, I know that "mount "informations are all in the "etc/fstab" file ,surely this "/etc/fstab" is supposed to be on the board uclinuxOS,not the one on the linux host ,but but how could I make the" fstab "onto the board ,which should I choose when I config the kernel in the "customize vendor/user setting "menu and "customize kernel setting"menu?  Trouble you for another quesion,in the "customize vendor/user setting "menu, I  found that the same bash command (e.g.ping etc.)exits in different submenu, I want to know what is the difference of them and what useness are these submenus .  Thanks a lot.

1. nfs problem, 

on the server, disable firewall, disable SElinux. try mount nfs to the server from another Linux PC.  2. same program in different submenu some programs provide integration of several commands, eg, busybox, sash, tinylogin. there are standalone program, too. there are many options, depend on features and size. integration saves disk space, but dose not save memory space. for nfs mount, you should use the mount in busybox with nfs mount enabled.

Hello everybody, I am configuring the kernel for the DE2 board and there are ALOT of options and applications. How should I configure the kernel to make use of the DE2_NET project?
