[[公開メモ]]

* Petalinux 2018.3 を使って zynq-7000 用のブートSDカードを作る [#xf4d6dda]

[[電気回路/zynq/Petalinux2018.3環境を整える]] の続き。

以前、Petalinux 2016.4 でやった [[電気回路/zynq/Petalinux のビルド#aabc4100]] および [[電気回路/zynq/Petalinux のカスタマイズ#p4f8f224]] を新しいバージョンでやり直すことになる。

#contents

ターゲットは z-turn board で、これまで以下のような記事を書いていた。

#ls2(電気回路/z-turn,compact)

Petalinux により標準でサポートされている環境ではない(BSP が提供されていない)ので、
いろいろ調べながらやることになる。

* プロジェクトの作成 [#o40aac7b]

z-turn ボードに対応する BSP は配布されていないので、
zynq の汎用テンプレートを使ってプロジェクトを作る。
（BSP が配布されているシステムであればプロジェクト作成時に BSP を指定する）

プロジェクトルートに .gitignore が作られるので、
それをそのまま使うことで git による管理が基本的には可能となる。

ただし、現時点で petalinux の git 対応は完全ではないため、
プロジェクトを共有するには BSP を使った方が良い、との注意もあった。

 LANG:console

config.project と project-spec/ とがプロジェクトの本体になる。

* vivado のハードウェア設定を取り込みつつ基本の設定 [#o3495afb]

[[vivado のハードウェア設定を出力する>電気回路/zynq/Petalinux のビルド#a82e50cc]] の手順で 
vivado 2018.3 を使って design_1_wrapper.hdf  を作成して、zturn_v2018.3/hw_platform/design_1_wrapper.hdf  に置いた。
(.hdf ファイルの実体は hw_platform ディレクトリ内の主要ファイルを .zip 形式でまとめたもの)

実はこのとき、[[ZYNQ7 Processor System の SDIO Clock を 50MHz にしておかなければダメだった>#i8da51ff]]。

とりあえず何も変更せずに Exit し、git へ登録した。

** 罫線の表示がおかしい [#t90ff50a]

設定画面が現れたのだけれど・・・そのままだと罫線部分が文字化けする。

&ref(petalinux-config1.png,,50%);

https://islandcnt.exblog.jp/16849117/ の "-YaSTのライン化け-" にあるように、
PuTTY の設定で Charactor set を use font encording にすればいいらしい。

&ref(petalinux-config2.png,,50%);

ただこれだと LANG=ja_JP.UTF-8 での日本語表示がおかしくなる。

http://totech.hateblo.jp/entry/2014/09/22/071012 にあるように 
ja_JP.sjis ロケールを追加して、

 LANG:console
 $ sudo localedef -f SHIFT_JIS -i ja_JP ja_JP.SJIS
  character map `SHIFT_JIS' is not ASCII compatible, locale not ISO C compliant
 $ export LANG=ja_JP.sjis
  takeuchi@petalinux2019-3:~/petalinux/zturn_v2018.3$ ls -l
  合計 28
  drwxrwxr-x 7 takeuchi takeuchi 4096  3月 15 20:38 build
  drwxrwxr-x 3 takeuchi takeuchi 4096  3月 15 20:31 components
  -rw-r--r-- 1 takeuchi takeuchi  248  3月 15 20:14 config.project
  drwxrwxr-x 2 takeuchi takeuchi 4096  3月 15 20:30 hw_platform
  drwxr-xr-x 6 takeuchi takeuchi 4096  3月 15 20:36 project-spec

のようにすれば文字化けはなくなるのだけれど・・・今時 Linux ターミナルで
SJIS 使うのはどうなのかと。

LANG=C で進めるか、その都度 PuTTY の設定を変える方がよいのかもしれない。

** ロケール問題再び？ [#rfb10738]

ああそうか、そもそも [[電気回路/zynq/Petalinux のビルド#y0c5addb]] で痛い目に遭ったように、
Petalinux 自体が LANG=C 以外だとおかしな事になるんだった。

この問題は今も続いているようで、

 LANG:console
 $ export LANG=ja_JP.sjis
 $ petalinux-build -c kernel
  [INFO] building kernel
  [INFO] sourcing bitbake
  INFO: bitbake virtual/kernel
  Please use a locale setting which supports UTF-8 (such as LANG=en_US.UTF-8).
  Python can't change the filesystem locale after loading so we need a UTF-8 when Python starts or things won't work.
  ERROR: Failed to build kernel

のように、自ら検出してエラーを出してくれるようになっていた。

あれ？エラーメッセージを読むと UTF-8 なら問題ないと書いてある？？？

というかむしろ、

 LANG:console
 $ export LANG=C
 $ petalinux-build -c kernel
  [INFO] building kernel
  [INFO] sourcing bitbake
  INFO: bitbake virtual/kernel
  Please use a locale setting which supports UTF-8 (such as LANG=en_US.UTF-8).
  Python can't change the filesystem locale after loading so we need a UTF-8 when Python starts or things won't work.
  ERROR: Failed to build kernel

LANG=C だと UTF-8 が処理できないのでダメらしい。

** 暗号化ファイルシステムの問題 [#haea0979]

ということは、LANG=ja_JP.UTF-8 なら問題ない？

 LANG:console
 $ export LANG=ja_JP.UTF-8
 $ petalinux-build -c kernel
  [INFO] building kernel
  [INFO] sourcing bitbake
  INFO: bitbake virtual/kernel
  ERROR:  OE-core's config sanity checker detected a potential misconfiguration.
      Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
      Following is the list of potential problems / advisories:
  
      Failed to create a file with a long name in TMPDIR. Please use a filesystem that does not unreasonably limit filename length.
  Failed to create a file with a long name in SSTATE_DIR. Please use a filesystem that does not unreasonably limit filename length.
 
  Summary: There was 1 ERROR message shown, returning a non-zero exit code.
 ERROR: Failed to build kernel

今度は長いファイル名を使えないのがダメと言われた。

うわーこれきついや。

仕方がないので [[ホームディレクトリ暗号化の解除>電気回路/zynq/Petalinux2018.3環境を整える#e1dacfc9]]
の手順で暗号化を解除した。

すると、

 LANG:console
 $ source /opt/petalinux_2018.3/settings.sh
 $ petalinux-build -c kernel
  [INFO] building kernel
  [INFO] sourcing bitbake
  INFO: bitbake virtual/kernel
  Parsing recipes:   5%

のようにビルドが進むようになった。

Non-fatal となっているので、無視しても良いってことかしら？？？

以下のように、全体のビルドも問題なかった。

 LANG:console
 $ petalinux-build
  ...
 
  NOTE: Tasks Summary: Attempted 3065 tasks of which 2474 didn't need to be rerun and all succeeded.

  rootfs.cpio.bz2  rootfs.ext3.bz2        rootfs.jffs2    rootfs.testdata.json  u-boot.bin        zynq_fsbl.elf

してみると、いろいろとできていることを確認できる。

** 古い .hdf だとエラーが出た [#x53811ae]

同じソースから vivado 2016.4 で作成した hdf を与えた場合には
"Unable to find ps7 init files" というエラーが出た。

新しいバージョンで作り直さないとダメみたい。

によると、

> BOOT.binはbitstreamとFSBL、u-bootをひとつのバイナリに結合したもので、image.ubはkernelとrootfs、デバイスツリーのようです。

とのことなので、まっさらな FAT フォーマットの SD カードに BOOT.bin と image.ub だけ入れればいい。

 LANG:console
 $ sudo mount /dev/sdf1 /mnt/sdcard1
 $ sudo cp images/linux/BOOT.BIN images/linux/image.ub /mnt/sdcard1
 $ sudo umount /dev/sdf1

これでいいはず。

** SDIO Clock = 50MHz にしないとだめだった [#i8da51ff]

上でもちょっと書いたけれど
「[[電気回路/zynq/最新の fsbl で Linux が起動しない理由を調べる]]」 で判明したのと同じ原因で、
.hdf を作る際に ZYNQ7 Processor System の設定で SDIO Clock を 50MHz 
にしないとまったくうんともすんとも言わなかった。

&ref(sdio-clock-50MHz.png,,50%);

** FSBL の UART チャンネル設定 [#lfc4ab30]

起動するにはしたが 「[[電気回路/zynq/Petalinux のビルド#ode1428c]]」 と比べると、
FSBL 関連のメッセージが出ていないので、どこかで UART チャンネルの指定が足りていないっぽい。

対処法は・・・これかもしれない？

https://japan.xilinx.com/support/answers/61349.html

menuconfig で [Linux Components Selection] に移動し、[First Stage Bootloader] 
を無効にしたけれど components/ に fsbl のコードは存在しないのでどうしようもない。

えー？
