Quick guide for porting linux to ALTERA DE2-70

Platform and tools:  Ubuntu 9.04

 

Step 1,   Download the nios linux tallbal

 

 

wget http://www.niosftp.com/pub/linux/nios2-linux-20090929.tar

 

or use xunlei to fix it.

 

Step2,

 

tar xvf  nios2-linux-20090929.tar

cd nios2-linux

./checkout

 

Step 3,   Generate the fpga.h file

First, a nios processor should be constructed.

 

Use any one of examples in the DE2 cd.  For instance, use  E:/fpga/de2_70/DE2_70_demonstrations/DE2_70_NIOS_HOST_MOUSE_VGA

 

Then add a mmu as pics bellow.   Remember to click the Auto-Assign Base Addresses, or it will sthick on the booting stage.

Click Generate, this takes a while.

 

Alfter above steps, we can get fpga.h file now.Open Nios II Command Shell,   cd to this DE2...vga DIR,  and key in the following commond

 

sopc-create-header-files --single fpga.h

 

start complication

 

copy ***VGA.sof to c:/

 

then copy the fpga.h file to /softs/nios2-linux/linux-2.6/arch/nios2/include/asm

 

Step 4     Building the linux kernel

 

Add "PATH=$PATH:~/nios2-linux/toolchain-mmu/x86-linux2/bin" to ~/.bashrc file

cd /softs/nios2-linux/uClinux-dist

make menuconfig        

#Enable the dma9000 and mtd drivers

make

cd images

copy linux.initramfs.gz  to windows xp  c:/


Step 5   Flash Linux kelnel to DE2-70

 

Open Nios II Command Shell,   cd to this DE2...vga DIR,  and key in the following commonds

 

nios2-configure-sof  ***.sof

nios2-download -g linux.initramfs.gz

nios2-terminal
