HelioボードでLinuxをブート

Helioボードが来たので、SDカードにLinuxのブートイメージを書いて、Linuxをブートした。

Helioボードには、説明書が紙1枚だったので、RocketBoards.org の Macnica Helio SoC Evaluation Kit のページの Getting Started (v0.31 Preliminary, May.15, 2013) を見ながら設定を行った。

・SDFormatter でSDカードをフォーマット

・Linux SD Card Image (Linux kernel 3.8, Preliminary, May.29, 2013)をダウンロードして、DiskImager でイメージをSDカードにWriteした。

・マニュアルに従って、USB-to-SerialのドライバをWindowsパソコンにインストールした。

・USBケーブル（ミニB）を挿すと、ピポンと言って、ドライバのインストールが始まった。USB-to-SerialのICは、USB給電のようだ。気が利いているね。

・Tera Termを立ちあげ、ボー・レートを 57600 bit/sec に設定した。

・Helioボードの設定ピンやDIP SWはマニュアルの通りだった。

・Helioボードに電源プラグを差し込んだ。（電源SWは未実装で、下のパターンに、たぶん0Ω抵抗が付いていた）



・Linux が立ち上がった。


・ルート・ディレクトリを ls してみた。


ZedBoardのZynq-7020 より、FPGAの温度が高い感じがする。FPGAの回路が沢山入っているのだろうか？
温度を測ってみたら、47.3度だった（放射温度計）。ちなみに机の温度は28.4度だ。ず～と触っていることは難しい。

Linuxの起動メッセージを貼っておく。sshd や httpd も起動しているようだ。
