安裝步驟

事前準備

  • echo $SED 必須為空，或者unset SED
  • echo $GREP_OPTIONS 不可含有 --initial-tab
  • 添加 PATH 至 ~/.bashrc
    • /staging_dir/host/bin
    • /staging_dir/toolchain-<platform>-<gcc_ver>-<libc_ver>/bin
  • 支援硬體表
  • 不能使用 Root User 進行 Compile

# m -> <M> -> package (opkg to install)
# n -> < > -> 不處理
# 存檔後會產生 /.config

Image 位置

E.g. if your is ~/openwrt/trunk, the binaries are in ~/openwrt/trunk/bin/ar71xx.

make dirclean ; make defconfig ; make V=s -j1

# 修改 /etc/rc.local
chown 777 /etc/rc.local

Misc

.config - OpenWrt Configuration
编译单个软件，进入编译选项选择要编译的软件后，如果没有make需执行以下：
make tools/install
make toolchain/install
然后编译指定的软件：
make package/name/compile

mount -o remount,rw /

opkg update 失敗

Signature check failed

修改/etc/opkg.conf
註解 option check_signature 1
Signature check failed问题解决(附opkg.conf)

wget return 8

修改
/etc/opkg.conf
/etc/opkg/distfeeds.conf

Pi 3 的情況是指向空目錄

LinkIt Smart 7688

透過 wifi 連入後，網頁進入 mylinkit.local 設定 root 密碼

設定成 station mode 後，可透過 ssh root@mylinkit.local 連入

使用 mraa 套件來操控 GPIO

自製 ipk
