Programming OpenRISC on Altera De0-nano
Yi-Chiao Lin
Path set
1.安裝 quartus:
chmod +x ~/Downloads/altera_installer.external.sh
~/Downloads/altera_installer.external.sh
2.vim .bashrc
3.Add $PATH:
Make (.sof)
git://openrisc.net/stefan/orpsoccd ~/orpsoc/boards/altera/de0_nano/syn/quartus/runmake asm
Make (.sof)
De0_nano USB BLASTER(.rules)
cd /etc/udev/rules.d/gedit 51-usbblaster.rules
killall jtagdsudo /opt/altera/12.1sp1/quartus/bin/jtagd
Programming Hardware
make pgm(quartus_pgm --mode=jtag -o p\;orpsoc.sof)
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
OpenOCD Troubleshooting
1.error:libusb-1.x
Solution:sudo apt-get install libftdi-dev libusb-1.0-0-dev
OpenOCD Troubleshooting
2.TCL error:
Solution:Remove $PATH : /opt/altera/12.1sp1/quartus/bin
Check Uart pin
cd ~/orpsoc/boards/altera/de0_nano/syn/quartus/tcl
vim UART0_pin_assignments.tcl
Check Uart pin
