9. you should try out the new kernel.

follow step5, build kernel as before, but "cd ~/linux-2.6.15.4" .

if you will develop drivers, you should use the new kernel.

While testing the new kernel, I discovered that "socket.h" needs a patch. Also, the SMC91111 driver is missing its header file. This soon becomes apparent when you enable Networking -> Networking support, then attempt to build new kernel.

Save the following as ~/download/linux-nios2-03.diff

Apply the patch as follows....

cd ~/linux-2.6.15.4
#  Patch socket.h
patch -p0 <~/download/linux-nios2-03.diff
#  Salvage the missing SMC91111 header file
cp ~/linux-2.6.x/drivers/net/smc91111.h drivers/net
#  Config the kernel
make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- menuconfig
#  Compile the kernel

Pls let me know how it goes
