A board layer is introduced. The location of fpga header and config.c are moved. Please check out the [Board layer] section in the wiki,

    does this branch work on DE2-70 well?

    it seems that this release only supports 3c120 and NEEK board.

    I am afraid whether this tar will support DE3?or could you give some solution to add DE3 platform in menuconfig.

    lulin and wangyipin:

    Please see this page linked in the original post:

    http://nioswiki.com/linux

    Porting Linux to any particular board involves running the sopc command listed on the wiki to create a header file and choosing the drivers for your peripherals in menuconfig. Once you have it working you can save this configuration as a new "vendor" -- this is also documented on the wiki.

    As far as I know, the distribution is moving away from shipping preconfigured headers, much less kernel/driver configurations for specific boards in the distribution.

    Hi

    I search for this solution as well 45 minutes ago.

    Before this i have ported uclinux on the stratix II developement board.

    I took the DE3_150_DDR2_1G_1RANK reference design from the de3 system design cd and try port uclinux on that system. First problem i encounter is that the nios2-terminal hang after this display on the terminal:

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

    nios2-terminal: "USB-Blaster [USB 4-1.2]", device 1, instance 0

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

    Then i checked the system design again and found that the cpu reset vector and Exception vector are on onchip_mem

    Then I disable the onchip_mem and connect the cpu instruction master and data master to the altmemddr which is the high performance DDR2 SDRAM. Then i reconfigure the cpu reset vector and exception vector to altmemddr, regenerate and recompile the design.

    After all the configuration, the uClinux amazingly boots up. :D

    hope this helps.
