More than 1 year has passed since last update.

IchigoJamをRaspberry Pi上で動かすためのSDカードを作る手順です。この手順で、今の所3種類のSDカード(Transend,Toshiba,Team)に書き込みが出来ていますが、同一メーカーでもものによって起動しないものが出たりして、何らかの相性問題がどうも残ってはいるようです。(追記:Teamは成功例もありますが、どうしてもうまくいかないケースもありました)

まず、MacでSDカードをフォーマットする際の注意点が、EFIパーティションです。GUIのディスクユーティリティのデフォルト設定では、見ることが出来ないため、指示通りにファイルをコピーしたのに動かない、という場合はこちらをチェックします。 diskutil list でSDカードの構成をチェックし、EFIが出来てたらフォーマット失敗です。

/dev/disk2 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *7.9 GB     disk2
