2. Path set
1.安裝quartus:
chmod +x ~/Downloads/altera_installer.external.sh
~/Downloads/altera_installer.external.sh
2.vim .bashrc
3.Add $PATH:

3. Make (.sof)
git://openrisc.net/stefan/orpsoc
cd ~/orpsoc/boards/altera/de0_nano/syn/quartus/run
make asm

4. Make (.sof)

5. De0_nano USB BLASTER(.rules)
cd /etc/udev/rules.d/
gedit 51-usbblaster.rules
killall jtagd
sudo /opt/altera/12.1sp1/quartus/bin/jtagd

6. Programming Hardware
make pgm
(quartus_pgm --mode=jtag -o p;orpsoc.sof)

7. OpenOCD install
(1)git clone git://repo.or.cz/openocd.git
(2) cd ~/openocd
(3) ./bootstrap
(4) ./configure --enable-ftdi --enable-usb_blaster_libftdi
--enable-maintainer-mode
(5) make

8. OpenOCD Troubleshooting
1.error:libusb-1.x
Solution:
sudo apt-get install libftdi-dev libusb-1.0-0-dev

9. OpenOCD Troubleshooting
2.TCL error:
Solution:
Remove $PATH : /opt/altera/12.1sp1/quartus/bin

10. Check Uart pin
