ZYBO-Z7を用いたLチカ(Petalinux編)
ZYBO Z7(20) を買ったので、PetalinuxによるLinuxビルドを簡単なLチカを行う。 使用バージョンはVivado/SDK/Petalinux 2017.2
実施手順
- 事前準備
- VivadoでGPIOによるLED回路作成、bitstreamの生成
- Petalinuxの設定とビルド
- SDカードへの書込み
- ブート・動作確認
1. 事前準備
- Vivado Version 2015.1 and Later Board File Installation を参考に予めZYBO Z7のボードファイルをインストールしておく
- FTDI Chip より必要なUSB-JTAG/UARTのドライバをダウンロードし、インストールしておく
2. VivadoでGPIOによるLED回路作成、bitstreamの生成
Vivadoの設定
プロジェクト名「lnxled」。 予めインストールしておいたボードファイル「Zybo Z7-20」を選択。
回路の作成
Flow Navigator > IP INTEGRATOR > Create Block Design
デフォルトの「design_1」でOK
中央の「+」ボタン(Add IP)をクリックして、「zynq」と検索、Enterで追加。
緑色でアシスタンスされている「Run Block Automation」をクリックします。
デフォルトのまま「OK」をクリック。
BoardタブからGPIOの4LEDsをクリックする。
デフォルトで選択されているGPIOのままOKをクリック。
アシスタンスされているRun Connection Automationをクリック。
デフォルトのままOKをクリック。
AXI GPIOを開く。
IP ConfigurationのDefault Tri State Valueを「0x00000000(すべて出力)」に設定する。
Validate Designを実行し、問題ないことを確認する。DDR周りでclock skew valueが4か所Critical warningとなるが気にしない。
Address Editorタブに切り替えて、 Offset Addressを確認しておく。
今回の場合は、0x41200000。
Sourcesタブの「design_1」を右クリックしてCreate HDL Wrapperを実行。
Flow Navigator > PROGRAM AND DEBUG > GenerateBitstream をクリックしてBitstreamが生成されるのを待つ
bitstreamが生成されたら、File > Export > Export Hardwareを選択。「include bistream」のチェックは入れておく。
Vivadoの作業は終了
3. Petalinuxの設定とビルド
場所はどこでも構わないがとりあえずプロジェクトディレクトリ(lnxled.srcsとかがあるところ)でPetalinuxのプロジェクトを作成する。
$ petalinux-create -t project -n lnxled.lnx --template zynq INFO: Create project: lnxled.lnx INFO: New project successfully created in /home/aster_ism/Project/zybo-z7/lnxled/lnxled.lnx
Petalinuxのプロジェクトディレクトリに移動して、コンフィグを行う。
$ cd lnxled.lnx $ petalinux-config --get-hw-description ../lnxled.sdk INFO: Getting hardware description... INFO: Rename design_1_wrapper.hdf to system.hdf [INFO] generating Kconfig for project
コンフィグ画面が出てくるがそのままExitする。
しばらく設定が完了するまで待つ。

設定ファイルが生成されたらビルドを実行する。

INFO: Copying Images from deploy to images INFO: Creating images/linux directory [INFO] successfully built project
最後に、BOOT.binを作成します
$ petalinux-package --boot --fsbl images/linux/zynq_fsbl.elf --fpga images/linux/design_1_wrapper.bit --u-boot --force INFO: File in BOOT BIN: "/home/aster_ism/Project/zybo-z7/lnxled/lnxled.lnx/images/linux/zynq_fsbl.elf" INFO: File in BOOT BIN: "/home/aster_ism/Project/zybo-z7/lnxled/lnxled.lnx/images/linux/design_1_wrapper.bit" INFO: File in BOOT BIN: "/home/aster_ism/Project/zybo-z7/lnxled/lnxled.lnx/images/linux/u-boot.elf" INFO: Generating zynq binary package BOOT.BIN... INFO: Binary is ready. WARNING: Unable to access the TFTPBOOT folder /tftpboot!!! WARNING: Skip file copy to TFTPBOOT folder!!!
Warningが出てますが気にしなくていい。
BOOT.bin と image.ub をSDカードにアクセスできる場所にコピーします。
$ cp images/linux/BOOT.BIN /mnt/windows/ $ cp images/linux/image.ub /mnt/windows/
4. SDカードへの書込み
先ほどのBOOT.binとimage.ubをFAT32でフォーマットされたmicroSDカードに書き込みます。
普通にデバイスの取り外しを行い、SDカードを取り外します。
5. ブート・動作確認
ZYBO Z7にmircoSDカードを差し込み、JP5(ZYBO Z7のロゴの近く)が「SD」になるように設定して、電源を入れる(電源を入れないとSerialポートが認識しないため)。MobaXtermを立ち上げて、Serialのセッションを追加。スピードは115200bps。
すぐに起動してしまってログが見えなかったので、起動ログを見るためにPS-SRSTボタンを押す。 (起動ログ、Ether等設定していないので、Warningが出ているが、とりあれず今回のデモでは関係ない)

メモしていたAddress Offset を使ってLEDを光らせる。アドレスに1を書き込むと点灯し、0を書き込むと消灯する。0~3ビットがそれぞれLD0~3に対応している。従って、LD0を点灯させる場合は下記の通り。
# devmem 0x41200000 32 0x1
(わかりづらいがLD0スイッチの上のLED右端が点灯)
4つとも光らせるなら
# devmem 0x41200000 32 0xF
