在OK3568-linux-source/buildroot/configs/OK3568_defconfig中添加
+BR2_PACKAGE_NTP=y
+BR2_PACKAGE_NTP_SNTP=y
+BR2_PACKAGE_NTP_NTP_WAIT=y
+BR2_PACKAGE_NTP_NTPD=y
+BR2_PACKAGE_NTP_NTPDATE=y
+BR2_PACKAGE_NTP_NTPQ=y
+BR2_PACKAGE_NTP_NTPTIME=y
+BR2_PACKAGE_NTP_TICKADJ=y

然后删除OK3568-linux-source/buildroot/output/OK3568/build/ntp-4.2.8p10文件
从新编译刷机即可
