标题: MY-I.MX6_MB V2.4底板RTC
底板：MY-I.MX6_MB V2.4 核心板MYZR_IMX6 CB_V2.1 系统：android 4.4.2
软硬件全都是myzr提供的请问现在RTC时钟无效，掉电后无法保持时间，这个是哪里的问题

你好，默认的镜像在android4.2.2有编译，在android4.4.2没编译isl-1208.c的驱动，还有你可以按我下面的方法修改驱动就可以了
首先把make menuconfig 加上配置isl1208
在rct-isl1208.c的文件修改:
struct rtc_time rtc_tm;
struct rtc_time set_tm;
int err = 0;
unsigned long rtc_secs, default_secs=946684800;//2000-1-1

probe函数里的return 0之前再加
err = isl1208_i2c_read_time(client, &rtc_tm);
if (err)
      return err;
err = rtc_tm_to_time(&rtc_tm, &rtc_secs);
if (err)
      return err;
//printk("rtc_secs=%d\n",rtc_secs);
if(rtc_secs <= default_secs)
{
      rtc_time_to_tm(default_secs, &set_tm);
      isl1208_rtc_set_time(&client->dev, &set_tm);
}

在kernel_imx文件夹下运行make menuconfig吗？
运行之后提示错误

已经按照你说的加进去了可是还是不好使呢

你好，首先看看有没生成isl-1208.o的文件，如果没有的话，有可以配置ISL1208没配置，
我记得有个文件是设置默认内核配置TARGET_KERNEL_DEFCONF := imx6_android_defconfig
你在deviece目录搜索文件，用如下命令：
grep TARGET_KERNEL_DEFCONF device -r
最后把这个“TARGET_KERNEL_DEFCONF := imx6_android_defconfig”注释掉
