[ART-Linux-Welcome] Root-NFS: Server returned error -13で起動しない
|

こんにちは。
早速ですがAPが起動しないので助けていただけないでしょうか？
よろしくお願いいたします。
ART-Linuxを使ってリアルタイム・プログラミングを勉強しようと思い、初めて
インストールにトライしました。
しかし、末尾のシリアル端末のログに示すように未だ起動していません。
理由が分からず困っています。
試してみることなど何かアドバイスがあればご教授願えないでしょうか。
NFSの接続で失敗しているようなのですが、BSP側でnfs-serverが実行中であるこ
とは確認してあります。
