good, so you have the buildroot/gcc/uclibc/busybox successed?

use the mininal .config copied from the kernel.config or kernel2.config attached.

only change the console (either serial or jtag). do not change any other setting. change others only after you have a successful boot.

Hi hippo.

After I did, It likes follow:

~/buildroot/build_nios2/staging_dir/bin has tools .

~/buildroot/toolchain_build_nios2 has binutils-2.15 ,binutils-2.15-build,uClibc etd dirs.

It&#39;s hard for me to make vmlinux.On sopc builder,I made a "nios2+jtag+onchipram+cfi+ext_flash" system, and get a ptf file.During config the kernel, I did what you said (oad kernel.config and just change the serial console to jtag). But it still can&#39;t succeed.

The most errors are like :undefined reference to `__udivsi3&#39;

undefined reference to `__modsi3&#39;

Please give me some advice. is it because ptf file or config problems? I trid many ways , but failed.
