USB host problem on DE2 board

hello,

i am trying to access the usb host on my de2 board using uclinux. i have followed the steps in the wiki at:

http://nioswiki.jot.com/wikihome/operating...host?revision=4 (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/usbhost?revision=4)

i can download the image file to the board, however, when i start the terminal to boot the kernel, it hangs while loading the usb driver. here is the output i receive:

[SOPC Builder]$ nios2-terminal.exe

nios2-terminal: connected to hardware target using JTAG UART on cable

nios2-terminal: "USB-Blaster [USB-0]", device 1, instance 0

nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)

Uncompressing Linux... Ok, booting the kernel.

At this point it stops indefinitely.

When I compare this with the output from the wiki, I notice that the following lines appear in my output and not on the wiki:

isp1362_hc_reset:

clock not ready after 20ms

I'm thinking that I am missing some extra configuration for the FPGA. Currently, I download DE2_NET.sof to my DE2 board as specified in:

http://nioswiki.jot.com/wikihome/operating...s/tryoutuclinux (http://nioswiki.jot.com/wikihome/operatingsystems/tryoutuclinux)

Does anyone have any idea what could be causing this problem? Help is this matter would be greatly appreciated.

Hi , kael

I met same problem.

You need recomplied DE2_NET project again.

Regards

Faye

The messages

isp1362_hc_reset:

clock not ready after 20ms

appear since the 2.6.17 kernel driver,

the reason is that the reset function is now called and was not with 2.6.11 kernel driver.

It does not matter.

Why there is a problem with the clock check on De2 Brd needs investigation.

Do you mean simply recomple the DE2_NET project, or does something need to be reconfigured before recompiling?

Thanks for the quick feedback.

Hello everyone and thanks for your replies.

Going off what Faye suggested, I found the CD that came with the board that has all of the demonstrations mentioned in:

http://nioswiki.jot.com/wikihome/operating...s/tryoutuclinux (http://nioswiki.jot.com/wikihome/operating...s/tryoutuclinux)

I used the DE2_NET.sof from the CD and it works just fine! It seems there is a problem with the file posted in the wiki.

Thanks again.
