Hi Jeff,

Both of errors indicate your user layer or kernel driver is using a wrong IOCTL command, maybe your RTC_RD_TIME of user layer doesnot match the RTC_RD_TIME of kernel layer. so driver return a '--ENOTTY' error no.
The better thing is you can write a rtc test application to identify your driver works well.
Maybe you can change other version hwclock for testing.
