OverClocked full featured problems

Hello All http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

First .. I&#39;d like to give GREAT thanks to Hippo .. and to all members of this fantastic forum .. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/cool.gif

I have a 2C35 board..

i was success in creating a bootable image having my application.. runs perfect on the standard processor..

i also had an overclocked (125 MHz) full featured processor .. i tested it wih my application as a single threaded program (no uClinux) .. it was working very good..

when i tried to build a new image based on the overclocked processor

it did very weird hings when booting ..

The question is :: is the problem with the " full feaured CPU " or with " OverClocking" ??

I have another question.. pls any1 help ..

I had enabled the ethernet .. i want to read large files from my PC to process them on the board ..

wha can i use to do so ...

is there a samba client for uClinux ?

or maybe Ftp ..?? but how ..?? i dont know how to configure ftp !

    Please check in sopc builder,

    the interrupt vector (ie, exception vector) should be in uClinux program memory, ie sdram.

    If you change sopc project,

    you have to "make clean" the uClinux-dist-test dir. Then run "make linux_hwselect ...." again.

    You may use ftp, setup ftp server on pc, and use ftpget/put/wget of busybox in nios2.

    Hippo .. thanks for your help ..

    but the default in SOPC is that the vector is loaded in SDRAM.. i did not change it .

    what i saw when trying to make hw_select

    and it hangs at this point .

    i tried several builds based on several ptf s .. with different cashes (Data and Instr) .. all the CPU builds gave almost the same error results..

    =====

    about files from my PC .. i saw an option in the eithernet called " Samba file system " .. will this make the job ?? or you sill suggest using ftp server on my PC ?

    ..

    Thanks a lot Hippo .. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

    SSSOOORRRRRRYYY .... Mr Hippo ..

    you were totally correct.. i fixed the interrupt vector .. and booted very fine ..

    the CPU&#39;s performance was perfect .. much more than thought.

    The single threaded prog. decoded some video sequence in 0.4 sec

    now ..under uClinux ... the same job was done in 0.22 sec

    if u dont mind.. pls reply me concerning the ftp or samba client ..

    thanks in advance

    It is easy to use ftp , http or nfs.

    you may setup any of these servers on PC.

    I didn&#39;t work through smb on nios2 yet. ( the code size is much bigger ).
