How to make applications run on nios2linux

[Altera_Forum]

Hi , 

How to make applications run on nios2linux by comman mount or ftpd. because the kernel is romfs, I can't mount linux host and windows xp. I can't send files to filesystem by ftpd either. Does somebody want to give a hand? My QQ is 332418170. Waiting for you!!

Welcome to darkstar. 

You can mount over initramfs. Add a PC to run Linux, and follow this link to build tools/kernel/apps, http://forum.niosforum.com/forum/index.php?showtopic=3174 (http://forum.niosforum.com/forum/index.php?showtopic=3174)

The initramfs is a read/writable root fs. It is not like romfs, which is read-only. 

 eg, to mount jffs2 "mount -t jffs2 /dev/mtdblock0 /mnt" will mount a mtd block device (0) to dir /mnt, /mnt is the mount point, you can use other dir for it. (you can even remount root fs with switch-root, but probably you won&#39;t)   eg, to mount nfs "mount -t nfs 192.168.1.2:/home /home" will mount the /home dir from nfs server 192.168.1.2 to dir /home .  eg, to mount vfat on ide/cf "mount -t vfat /dev/hda1 /var/www" will mount ide part 1, which is formatted as vfat, to dir /var/www

Hippo,Thank you for your reply. I have my own problems. I am not able to install Quartus5.0 on Fedora4.0 though I download quartus5.0_for_linux form ftp.altera.com.cn. After ./install run, there is message like "the installation is not finished, please insert CD." Oh, I am confused about that. Tried several times, none succedded. And I am not familiar with Fedora. Could you help me walk through the process on windowsXP? 

My QQ:332418170. Could you tell me your QQ ? http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/laugh.gif

I don&#39;t have QQ. 

 You need two PCs, use the windows XP with quartus 5.1sp1 and nios2 5.1sp1, which is used to compile hardware and download sof/elf/flash. Another Linux PC, (does not need quartus), used to build software, (tools/kernel/apps). Run a samba server (or client) on Linux PC, so that they can share files.  The zip files are at the end of post#1 in the thread.  You can use the Linux distribution which you are familiar. You should use the latest release of it. And you should have gcc 3.xx .

Hi MFM, 

We do it on Linux with buildroot tools. Jdhar and I had tried to do it on windows/cygwin but failed. That&#39;s the beginning of this story. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

good, so you have the buildroot/gcc/uclibc/busybox successed? 

 Use the mininal .config copied from the kernel.config or kernel2.config attached. Only change the console (either serial or jtag). DO NOT change any other setting. Change others only after you have a successful boot.

But it still can&#39;t succeed.  The most errors are like :undefined reference to `__udivsi3&#39;  undefined reference to `__modsi3&#39; Please give me some advice. is it because ptf file or config problems? I trid many ways , but failed.

The problem should be in library binding. Which Linux distribution did you use? 

 Do you have sdram on your board? you should run uclinux from it.
