i followed alex&#39;s steps to port the webserver. everything seems fine but i cant access the demo webpage. i can ping my de2 but cant access it with web browser. here are some of my questions: 1. must i follow the Buildrootguide to build the toolchain? i&#39;m totally new and i used the BinaryToolchain for newbies. 2. step 9: shud i run that cmd under ~/ws031202/LINUX dir or under ~/uClinux-dist-test/ dir? is it this cmd is suppose to replace the &#39;make linux image&#39; as in uClinuxDist? 3. step 10: whr shud i run this cmd? i tried the vmlinux file under ~/uClinux-dist-test/linux-2.6.xx/ (<= sry cant remember the numbers...) is it correct? Pls help. thank you in advance. ps. i&#39;m totally new n i hope my q doesnt sound stupid. i&#39;ll b glad if u would like to suggest anything.

there is no need to run the buildroot. you can use the rootfs, http://nioswiki.jot.com/wikihome/operating...2rootfs.tar.bz2 (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/binarytoolchain/nios2rootfs.tar.bz2) cd ~ tar jxf nios2rootfs.tar.bz2 The rootfs with busybox will be in ~/rootfs and ~/download/rootfs_list . you can add goahead to the rootfs. then update the initramfs path in kernel config. and rebuild zImage.

thx for your reply, hippo. i&#39;ve done wat u said and made the zImage. I download it to my DE2, i can go into the terminal but it show sth like this (http://i74.photobucket.com/albums/i248/jwlam1984/console.jpg) when i run any command. the list keep going on non stop. any idea wat&#39;s going on? pls help. thx again.

The message your getting are from the oom-killer (Out Of Memory killer) The DE2 board has not much memory... I&#39;m affraid that board will not run a webserver. You can however if you manage to get the SD-card running and put your rootfs and a swap partition on the SD card so you will get extra memory from losing the rootfs in RAM and the oom-killer will not kick in when there is swap-space available (unless that is full too). One thing to consider: Swap space is VERY slow memory... Your system won&#39;t run any faster with it, it will run. That&#39;s all. Hope this helps! Edit: He Hippo! We were typing the same info at the same time.... http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/wink.gif

it is running out of memory. how big is your initramfs? DE2 has only 8MB sdram. the rootfs from buildroot take up a lot of memory. what is the result of goahead with uClinux-dist-test ? which will use fewer memory. You should try to reduce the initramfs size. put some of user program and data onto other storages, eg, jffs2 on CFI, usb disk, or nfs.

putting the memory matter aside, did my setup refuse to work bcoz of the need for rootfs? b4 this i put everything under ~/uClinux-dist-test/romfs and i manage to boot it n run some cmd n ping. the only prob is tat i failed to open the test page with browser.

i have a little confusion here... where is the code dowloaded to when we run nios2-download? is it i have NOT been dealing with the onboard cfi flash in your UClinuxDist guide?

ps. sry for the hassle coz i kinda jump-start in learning fpga stuff by getting dirty thru hands-on straight away.

you can use nios2-download to write to sdram and sram, etc.
nios2-download does not write to flash.

you don't have to program flash everytime during apps development.
it is slow and flash have limited write life.

you should use nfs.
try program the sof and zImage (with network and nfs support) to epcs.

then mount nfs from your linux pc,
put your web server and content on the nfs share,
and test your apps out there.
