基本的には Using ARM on Debian の内容を実行。

最後のテストでは g++ が無いといわれ、インストールして再度実行したら以下のようなエラーになった。

マイクロSD カードは、最初 KIOXIA の 64GB SDXC を試したもののやはり容量がだめ。次に試したのが Panasonic の 32GB SDHC で、容量は大丈夫のはずなのに TEST でコンペアエラーになった。最後に KIOXIA の 16GB SDHC を買ってきたところ、これは TEST も正常終了して問題無く使えているよう。

(2024/May/16) クロスコンパイラはこちらが良いかもしれない。
