Raspberry Pi 3B+ 安裝 DS3231 RTC備忘

硬體
Raspberry Pi 3 Model B+
DS3231 模組

作業系統
自行編譯buildroot 2021.02

  • make raspberrypi3_64_defconfig
  • make menuconfig選擇好要安裝的程式
    • i2c-tools
  • make
  • 燒錄image至sd卡

修改config.txt <- 類似raspberrypi的bios設定
config.txt位於sdcard的第一個partition，開機進入buildroot linux後可以手動掛載此partition (/dev/mmcblk0p1)
config.txt要加入下面的資料
dtparam=i2c_arm=on

進入系統後執行下面指令

modprobe i2c-dev
modprobe i2c-bcm2835
modprobe rtc-ds1307
echo ds3231 0x68 > /sys/class/i2c-adapter/i2c-1/new_device

測試

hwclock -r
hwclock -w
