Message-ID: <3CBB4BA7.1010304@redhat.com> (raw)
I've used the NEW_TIME_C method to implement support for the Dallas 1501
RTC in my MIPS port . I now successfully read the hw clock, and the
date program works, and I can change the time.
However, the hwclock program tells me that it can't access the Hardware
Clock and tells me that /dev/rtc doesn't exist (although it actually
does) when running hwclock --debug. Also, I see an oddity that may be
related - ping reports zero (as in 0 msec) round trip times always. I
configured CONFIG_RTC into the kernel, and checked the major, minor of
/dev/rtc on my embedded ramdisk. Also, I don't see /proc/driver/rtc.
Is this normal behavior with NEW_TIME_C configurations? I've checked
my rtc_get_time and rtc_set_time, ..., like I said, the 'date' program
works, reading and writing to the clock.
Thanks,
Lanny DeVaney
