uClinux-dist compilation

Hello!

I have installed nios2 BinaryToolchain. Then I have downloaded uClinux-dist-20070130 and have applied uClinux-dist-20070130-nios2-02.diff.gz patch and "make vendor_hwselect" for my .ptf file. (All as is described in http://nioswiki.jot.com/wikihome/operating...ms/uclinuxdist) (http://nioswiki.jot.com/wikihome/operatingsystems/uclinuxdist)). But compilation has failed:

LD vmlinux

/opt/nios2/bin/nios2-linux-uclibc-ld.real: region ram is full (vmlinux section .text)

/opt/nios2/bin/nios2-linux-uclibc-ld.real: region ram is full (vmlinux section .data)

make[1]: *** [vmlinux] Error 1

What it means? Please, help!

PS

I work in Mandriva Linux 2007.

I beginner in Linux... Where I can find informatoin about nios2 BinaryToolchain and SW development in uclinux?

Thanks a lot!

    I just checked against Mandriva2007, and didn't find any problem.

    Perhaps, your source tree is corrupted. Remember, you should apply the patch ONLY ONCE.

    Please try remove the uClinux-dist tree, and install iagain.

    Moin,

    I don't remember exactly, but i think i got a message similar to this one, when i tried to use only the SRAM and not the DDR-SDRAM (on the CyclonII/NIOS Eval-board).

    So maybe it's related to the size of the available RAM. After that, i had to remove the old uClinux-tree and untar+patch+... again to get it work properly again.

    Cheers

    Thank you, hippo. I reinstall uClinux-dist tree but compilation failed with the same error! :-(

    What reasons can be?

    1)Wrong .ptf ?

    Then, what vertion of Quartus I should use?

    Can I use only SDRAM in my project?

    2)Wrong insallation of nios2gcc?

    I also use except for nios2gcc other gnu compilers on my PC.

    Need I in additional adjustments?

    Now try to reinstall Linux on my PC and recompile my project...

    Thanks!

    You must have SDRAM to run uClinux. But you still need a CFI flash to do hwselect, just add a dummy one if you don't.

    Or, you may try the ptf file , only to validate the toolchain,

    /opt/altera6.1/nios2eds/examples/verilog/niosII_cycloneII_2c35/standard/std_2C35.ptf

    what is the message during vendor_hwselect?

    Hello hippo!

    sorry for delay.

    1)vendor_hwselect finished ok. but compilation failed with the same error(no depend on .ptf)

    When I reinstall uClinux and nios2gcc as you described in nioswiki(word by word) there were error: cc command not found .So I think in Mandriva Linux I shoud do some more configuration. May be last time I made it incorrect...

    2)

    Has looked forward...

    Now we use lcd and drawing graphics directly(no OS). If I want to use framebuffer I have to install Avalon VGA Controller from nioswiki( I found only ptf file there) . But lcd we use has differrent timing and we use our own controller. Where I can download verolog source of Avalon VGA Controller to rewrite it? What about performance of framebuffer and microwin?

    Thanks!
