電気回路/zynq/Petalinux のビルド の履歴(No.1)

新しいプロジェクトを作る†

z-turn ボード用にビルドしたいのだけれど、公式にはサポートされていないので、 試しに zedboard 用のテンプレートを落としてみた。

LANG:console
$ file avnet-digilent-zedboard-v2016.4-final1.bsp
 avnet-digilent-zedboard-v2016.4-final1.bsp: gzip compressed data, last modified: Fri Dec 16 03:02:22 2016, from Unix
$ tar fxz avnet-digilent-zedboard-v2016.4-final1.bsp
$ cd avnet-digilent-zedboard-2016.4/
$ ls
 components  config.project  hardware  pre-built  project-spec

かなりいろいろ入ってる。。。

これを元にプロジェクトを作るのというのがチュートリアルだけれど、 ここではそんな便利なものはないので、zynq 用の汎用テンプレートを使って作る。

LANG:console
$ cd ~/z-turn
$ petalinux-create -t project --template zynq -n zturn-v2016.4
 INFO: Create project: zturn-v2016.4
 INFO: New project successfully created in /home/osamu/z-turn/zturn-v2016.4
$ cd zturn-v2016.4
$ git init

$ cat <<EOT > .gitignore

images
EOT
$ git add .
$ git commit -m "newly created"
$ ls project-spec/
 attributes  configs  hw-description  meta-user

どうやら project-spec/ というのが petalinux のプロジェクト本体のようだ。

vivado のハードウェア設定を出力する†

z-turn についていた mys-xc7z020-trd.xpr から [File]-[Export]-[Export Hardware...]

&ref(): File not found: "file-export-hardware.png" at page "電気回路/zynq/Petalinux のビルド";

[Include bitstream], [Local to Project] で OK

&ref(): File not found: "export-including-bitstream.png" at page "電気回路/zynq/Petalinux のビルド";

この操作により、

(project dir)/(project-name).sdk/design_1_wrapper_hw_platform_0/*

に design_1_wrapper.bit, ps7_init.* や system.hdf が出力されます。

&ref(): File not found: "exported-hardware-configuration.png" at page "電気回路/zynq/Petalinux のビルド";

vivado のハードウェア設定を取り込みつつ基本の設定†

上記フォルダ(コピーしたもの)を指定して petalinux-config すると、 ハードウェア設定を取り込んだ後、いろいろ設定可能なメニューが現れます。

LANG:console
$ cd (petalinux-project-dir)
$ petalinux-config --get-hw-description=../design_1_wrapper_hw_platform_1
 INFO: Getting hardware description...

&ref(): File not found: "petalinux-system-configuration.png" at page "電気回路/zynq/Petalinux のビルド";

とりあえず何も変更せずに Exit して設定を保存。

No real function for mknod について：
https://forums.xilinx.com/t5/Embedded-Linux/Strange-messages-about-shared-libraries-in-Petalinux/td-p/729766
libc6 2.24 固有の問題で出るエラーで、メッセージは無視して良いと書いてある

確かに、インストールされているのはバージョン 2.24 だ。。。

petalinux が推奨する Ubuntu 16.04 では libc6 は 2.23 になっている。 たぶん、Ubuntu が 2.24 はやばいと思ってまだ上げていないんだと思う。

えーと、上記リンクで紹介されているパッチを当てる先が見つからない？

ここを潰せばいいのは、わかる。

雰囲気的には meta にパッチを置いておくと、.tar.bz2 を展開し、 そのパッチを当ててからコンパイルしてくれる感じ？

むしろ、pseudo-1.7.5/ports/unix/wrapfuncs.in から mknod と mknodat をなくしちゃえばいいとか、 ないのかな？
