using µclinux in board 2C35

hello,

I followed the step of the http://www.nioswiki.com/linux

after this steps i arrived to

3. The images created are,

images/linux.initramfs.gz is the elf image with initramfs built-in

images/zImge.initramfs.gz is the compressed elf image with initramfs built-in

images/vmImage is compressed u-boot image

images/rootfs.jffs2 is jffs2 image, eg, cp rootfs.jffs2 /dev/mtd0. This is available when jffs2 is selected in kernel. Please note the flash erase sector size on 3c120 dev board is 128KB, you will have to specify "MKFS_JFFS2_FLAGS = -l -p -e 128" at the beginning of your product Makefile.

Connect USB Blaster cable to 3C120 dev board, download the sof and elf.

nios2-configure-sof ../3c120_default/nios2_linux_3c120_125mhz_top.sof

nios2-download -g images/linux.initramfs.gz

nios2-terminal

I would know if this version can work with 2c35 board (cyclone ii) ?

and how can download the sof and elf in borad ,we should use commande in linux or start the quartus II ?

because at know i'm not build our NIOS II processor with MMU

    Please make sure you have installed bash. The default shell of ubuntu is no good with quartus.

    Hello,Hippo

    yes i followed the step

    On Ubuntu, check if the default shell is "bash" , (the default might be "dash", which won't work with install scripts)

    ls -l /bin/sh

    This should give "/bin/sh -> bash",

    Otherwise, change it with,

    sudo rm /bin/sh

    sudo ln -s bash /bin/sh

    i have a bash

    so,is not the cause !

    Check that you have the correct path to the quartus tools in your $PATH environment variable

    hello,

    thank's

    yes i find a problem in PATH ,i changed to /opt/altera9.1sp1/quartus

    now

    when i execute ./n2sdk

    [NiosII EDS]$ quartus

    bash: quartus : (the quartus launched good)

    [NiosII EDS]$

    the only problem is

    [NiosII EDS]$ jtagconfig

    bash: jtagconfig : commande not found

    /opt

    because he don't indicated that we should creat script jtagconfig in this link

    http://nioswiki.com/operatingsystems/uclinux/quartusforlinux

    so how can creat this script jtagconfig?
