Zybo Z7 + Petalinux2019でEthernet0が繋がらない問題

f:id:fumimaker:20201003015020j:plain
Zybo Z7-20

Zybo on Petalinux2019.2でEthernetが繋がらない

これは前回の続きです.Petalinuxをインストールして,ビルドして焼いて実行する過程については以下の記事をご覧ください.

Zybo Z7-20でpetalinux2019を動かしました.Ethernetを使いたかったのですが,なぜかこのログのようにリンクしてくれていません.起動ログを見てもIPも取得できていないし,これは困りました. fumimaker.net

Ethernetは有効になってる?

Eth0が有効かされてないのかと思って一応確認してみた。DHCPになっていて問題ありませんでしたが一応追記しておきました.

vi /etc/network/interfaces

# Wired or wireless interfaces
auto eth0
iface eth0 inet dhcp
        netmask 255.255.255.0
        gateway 192.168.1.1
iface eth1 inet dhcp

でも変化はなかった。当然だがルーター側からも認識されてなかった.

PSの設定でEthernetは有効?

デフォルトで有効になってるはずだが確認した.やっぱり問題なかった.

f:id:fumimaker:20201001002331p:plain
ETH0は有効

PSの設定でMDIOはMIOになってるか?

Ethernetが繋がらないと調べると大量に出てくる情報がこれです.ボードファイルのバージョンによってはEthernetのPHYチップとの通信を担うMDIOがEMIOにデフォルトで設定されているらしい.確認したところ問題なくMIOになっていた.

f:id:fumimaker:20201001002336p:plain
MDIOは有効

ハードウェアの問題?

どうしてもEth0がリンクしてくれない.Petalinuxの問題かと思っていろいろ調べたけどやっぱり問題はなさそう.となるとやっぱりハードウェアの問題を疑うべきか? 諦めずに調べていたらこのような情報を発見した. github.com

クロックの問題?

情報によればEth0がExternalになってる?うせやろ?確認してみる.

f:id:fumimaker:20201001002341p:plain
マジでなってる
まじでなってる.IOPLLに変更した.なんでEthernetだけExtになってるんだ...罠すぎるでしょう.他の記事にはこのような情報がないってことはこのバージョンだけこのようなことが発生しているのでしょうか?厄介すぎますね.

ということでPSのハードウェア設定を変更して保存して,ビットストリームを再生成して,ハードウェアをエクスポートして,petalinux-configしなおして,petalinux-buildして,Packageして,焼きました.詳しいやり方については前回の記事を見てください.
