Intel Edisonが文鎮になりかけたので、初期化して修復した方法

Intel Edisonをいろいろいじっていたら突然下記のようなログが出て、一向にOSが起動しなくなってしまいました。

何かBattery Over heatと言われても、そもそも電源に繋いでいるしなと思いながらちょっと時間を開けて冷やしてしてみましたが同じエラーが出続けるのでこれは根本的な問題があると思い、いろいろ調べた結果初期化するしかないらしいという結論に辿り着きました。

なかなか文鎮化しかけたハードにさらに手を入れるのは素人では恐いのですが、やらざるを得なかったのとこれ関係のWebでの記事があまり見つからなかったので、備忘録の意味も含めて手順とログを残しておきます。

最新版の公式イメージをダウンロードする

公式サイトから最新版のYoctoをダウンロードします
執筆時(2017/02/09)はiot-devkit-prof-dev-image-edison-20160606-patch

解凍して、flashall.shがあることを確認する

Macの環境を整える

この後flashall.shを実行するのだが、その際にMacに入ってなさそうで必要なコマンドをインストールしておく
$ brew install gnu-getopt
$ brew install coreutils
(必要なのはgreadlinkだが、greadlinkはcoreutils内に入っている)
$ brew install dfu-util

  • 私の場合はこれで足りたが、他にインストールする必要がある人もいるかも知れないのでそれは適時実行してください

Edisonの準備

まずはシリアル経由でMacからEdisonに接続

$ screen /dev/cu.usbserial-XXXX 115200 -L
* usbserial-XXXXのXXXXはご自身の環境に合わせてください

Edisonをフラッシュモードにする

Edisonを起動して、「Hit any key to stop autoboot: 0」が出たタイミングで何かキーを押してautobotを止める。
そうすると「boot >」プロンプトになる

U-Boot 2014.04 (Apr 29 2015 - 03:53:19)

       Watchdog enabled
DRAM:  980.6 MiB
MMC:   tangier_sdhci: 0
In:    serial
Out:   serial
Err:   serial
Hit any key to stop autoboot:  0
boot >

この状態で「run do_flash」を叩いて、Edisonをフラッシュモードにする

boot > run do_flash
Saving Environment to MMC...
Writing to redundant MMC(0)... done
GADGET DRIVER: usb_dnl_dfu

このように待ち状態になったらEdison側の準備はOK

Mac側からフラッシュの開始

Mac側からflashall.shを起動する

$ cd ~/Downloads/iot-devkit-prof-dev-image-edison-20160606-patch  
$ chmod +x flashall.sh  
$ ./flashall.sh  

うまく行くとEdisonと繋いでいるシリアルの画面にてDFUのログが出始める

Hit any key to stop autoboot:  0
boot > run do_flash
Saving Environment to MMC...
Writing to MMC(0)... done
GADGET DRIVER: usb_dnl_dfu

文鎮になりかけた時はだいぶ焦りましたが、とりあえず戻せて良かったです。
ただ何がそうなってしまった原因なのか不明なのでそこを追求しないと。と

最後に一応今後のVerifyのためにMac側、Edison側それぞれの全ログを記載しておきます
