先 複製一份 hal_examples 的 example 成為自已的專案。

copy到 /project/linkit7697_hdk/apps/這個目錄裡面

cp -R mtk/project/linkit7697_hdk/hal_examples/gpio_configure_pull_state ../apps/gpio_ex_01

然後回到mtk sdk 的目錄下執行

./build.sh list

會list出來剛剛的專案資料夾

/gpio_ex_01/

root@e4bf41fef16e:/data/mtk# ./build.sh list

開始build

                                   下面的為build過程中會顯示訊息
