compact flash problem

Hi,

I'm working on the nios II cyclone board card.But I need to suppress the cf interface.So I did it in SOPC builder.

Then I need to implement linux in the nios board card.So I configured the kernel disableing "ATA/ATAPI/MFM/RLL support" and I built the kernel and the files system and I uploaded them in the nios. But when I open the shell SDK window, I cannot log on in Linux. I don't know why.Everything seems to be all rigth.I tried to do the same project but including the cf and it works.

Does the problem comes from the support I've disabled?

If somebody can help me, it'll be great!

Thanks, Dior.

    Hi Wentao,

    Here is the kernel booting message:

    "Welcome to Altera SOPC Builder

    Version 4.20, Built Tue Nov 2 09:42:35 PST 2004

    [SOPC Builder]$ nios2-terminal

    And it stops, wheareas when it works I&#39;ve exactly the same message but after the last ligne, it starts linux.

    Sorry, I mean the kernel booting messages generated by Linux itself, not by the local client on your PC. Those messages started with: 

    uClinux/Nios II
Altera Nios II support (C) 2004 Microtronix Datacom Ltd.
Built 1 zonelists
........

    If you post those messages, we should be able to find out what was wrong during the booting.

    BTW, what is your kernel console, uart or jtag?

    Hi Sylvain,

    You must have your kernel console directed to your uart. Change your kernel configuration: 

    device drivers ---> character devices ---> serial drivers
< > 8250/16550 and compatible serial support
--- Non-8250 serial port support
 Nios serial support
    Support for console on Nios UART
<*> Altera JTAG UART support
    Support for console on Altera JTAG UART

    Then you will be able to see the booting messages on JTAG.

    Hi wentao,

    Sorry, but I&#39;ve checked the kernel configuration and the kernel console isn&#39;t directed to the UART but to the JTAG like you showed it in the code.

    All good. Can you post your kernel booting message then?

    Hi Wentao,

    Once again, this is the point of my problem. I cannot obtain the kernel booting message. The NiosII SDK shell window cannot display the kernel booting message and I don&#39;t know why. I&#39;ve this problem only when I worked on a quartus project where the cf is removed.
