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...

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. <div align='right'><{post_snapback}> (index.php?act=findpost&pid=19676) --- Quote End --- [/b] --- Quote End --- Hi , kael I met same problem. You need recomplied DE2_NET project again. Regards Faye
