Having followed the instructions, modified some defines in nios2.h and enabled the networking support, finally got linux image for my DE2-70. Unfortunately, the kernel boot get stuck:

Linux/Nios II-MMU

init_bootmem_node(?,0x4476, 0x4000, 0x6000)

free_bootmem(0x4476000, 0x1b8a000)

reserve_bootmem(0x4476000, 0x400)

Built 1 zonelists in Zone order, mobility grouping on. Total pages: 8128

Inode-cache hash table entries: 2048 (order: 1, 8192 bytes)

We have 24576 pages of RAM

TCP: Hash tables configured (established 1024 bind 1024)

Any ideas what else should be done to make it work?

    go back to "Creating a Nios II Design with an MMU" page.if you assigned the s1 and s2 with different addresses, try a same address.

    or you can select auto-assign base addresses in SOPC Builder for why.

    good luck.

    my problem is just the same with chonger's at that time, so I found here but there was no answer.

    after that, I try auto-assign in SOPC Builder and found they have same address by default.

    so I modified and figured it out.

    maybe we have the different reason.

    sorry that can't help you.
