Prerequisites

This page presents how to create an SD card using pre-compiled Linux binaries package and use it to boot Linux on the Altera Cyclone V SoC Development board.

The following items will be needed in order to succesfully get started with Linux on the Altera SoC Development board:
  • Altera SoC Development board (include power supply and required accessories).
  • Host computer running Linux
  • External USB micro SD card reader (or host computer with built-in micro SD card reader). Alternatively a micro SD to SD card adapter can be used if the host PC or the reader has a SD slot but no micro SD slot.
  • 4GB (or larger) micro SD or micro SDHC card. The actual image is 2GB, but most SD cards have some amount of invalid sectors, so using a 2GB SD card might not work.
  • Local Ethernet network, with DHCP server (will be used to provide IP address to the board).

Creating SD Card

This section explains how to create the SD card necessary to boot Linux, using the SD card image available with the precompiled Linux binaries package.

The steps required to create the SD card for the Cyclone V Development board are:

1. Download the GSRD release binaries:
$ wget http://releases.rocketboards.org/release/2013.11/gsrd/bin/linux-socfpga-gsrd-13.1-cv-bin.tar.gz

2. Extract the compressed Linux SD card image from archive
$ tar -xzf linux-socfpga-gsrd-13.1-cv-bin.tar.gz

3. Expand the compressed Linux SD card image
$ gunzip linux-socfpga-gsrd-13.1-cv-bin/sd_image_cyclone5.bin.gz

4. Determine the device associated with the SD card on the host by running the following command before and after inserting the card in the reader:
$ cat /proc/partitions 

Let's assume it is /dev/sdx.

5. Use dd utility to write the SD image to the SD card:
$ sudo dd if=linux-socfpga-gsrd-13.1-cv-bin/sd_image_cyclone5.bin of=/dev/sdx bs=1M

Note we are using sudo to be able to write to the card.

6. Use sync utility to flush the changes to the SD card:
$ sudo sync

The steps to create the SD card for the Arria V development board are similar:
$ wget http://releases.rocketboards.org/release/2013.11/bin/linux-socfpga-gsrd-13.1-av-bin.tar.gz
$ tar -xzf linux-socfpga-gsrd-13.1-av-bin.tar.gz
$ gunzip linux-socfpga-gsrd-13.1-av-bin/sd_image_arria5.bin.gz
$ sudo dd if=linux-socfpga-gsrd-13.1-av-bin/sd_image_arria5.bin of=/dev/sdx bs=1M

Configuring Board

This section presents the necessary board settings in order to run the GSRD on the Altera SoC development boards.

Cyclone V Development Board

The following image is provided to make it easier to find these locations on the board:

  • Configure Jumpers
Jumper Setting
J5 open
J6 shorted
J7 shorted
J9 open
J13 shorted
J16 open
J26 left shorted
J27 right shorted
J28 left shorted
J29 right shorted
J30 left shorted
J31 open
  • Configure switches
Switch Setting
SW1 All OFF
SW2 All OFF
SW3 1:ON 2:ON 3:ON 4:ON 5:ON 6:ON
SW4 1:OFF 2:OFF 3:ON 4:ON
  • Make sure the power switch SW5 on the board is turned OFF.
  • Connect mini USB cable from the host PC to the board connector J8.
  • Connect Ethernet cable from board connector J2 to the local network (hub or switch). This is needed only if networking is to be used.
  • Connect 19V power supply cable to the board connector J22.

  • Make sure the power switch SW5 on the board is turned OFF.
  • Connect mini USB cable from the host PC to the board connector J22.
  • Connect Ethernet cable from board connector J13 to the local network (hub or switch). This is needed only if networking is to be used.
  • Connect 19V power supply cable to the board connector J34.

Configuring Serial Connection

The board has a built-in USB to Serial converter chip that allows the host computer to see the board as a virtual serial port.

Both Ubuntu 12.04 and CentsOS 6.3 have built-in drivers for the USB to Serial converter chip that is on the Altera SoC Development board, so no driver installation is necessary on those platforms.

1. The virtual serial port is usually named /dev/ttyUSB0. In order to determine the device name associated with the virtual serial port on your host PC, please perform the following:
  • Use the following command to determine which USB serial devices are already installed: ls /dev/ttyUSB*
  • Power up the board using the switch SW5. The board LEDs will turn on.
  • Use the ls /dev/ttyUSB* command command again to determine which new USB serial device appeared.

2. Install minicom application on host PC, if not already installed.
  • On CentOS, use sudo yum install minicom
  • On Ubuntu, use sudo apt-get install minicom

3. Configure minicom
$ sudo minicom -s

Under Serial Port Setup choose the following
  • Serial Device: /dev/ttyUSB0 (edit to match the system as necessary)
  • Bps/Par/Bits: 115200 8N1
  • Hardware Flow Control: No
  • Software Flow Control: No
  • Hit [ESC] to return to the main configuration menu
Select Save Setup as dfl to save the default setupSelect Exit.

Notes:
  • Depending on your board version, the USB Serial device may not be available to your host PC until the board is powered up. This will prevent you from starting minicom until the board is powered up. If the SD card is already inserted, the boot process will have already started by the time minicom is started, and you may miss some of the boot messages.
  • To avoid the above problem, you may use this sequence:
    1. Power up the board without the SD card inserted,
    2. Start minicom
    3. Insert SD card and press HPS warm reset button (S8 on Cyclone V board, S10 on Arria V board)

Booting Linux

This section presents how to boot Linux on the board. The required steps are:
  1. Prepare SD card
  2. Configure Board
  3. Configure Minicom
  4. Start Minicom - it will use the defined configuration
  5. Power up board (or, if already powered up, press Warm reset button or power cycle)
  6. Minicom will show Linux booting, then asking for the username. Enter root then press ENTER. No password will be required.
  7. The four FPGA LEDs on the top right corner of the board will light ON and OFF sequentially.AlteraLinuxGettingStarted.png
  8. The IP address of the target board will be displayed on the 1st line of the LCD display. Note that the IP address is displayed only at the boot time, it is not updated if the IP address is changed later, for example by the user.
