[Buildroot] hwclock doesn't work

[Buildroot] hwclock doesn't work

[JNY]

When I try to use hwclock on my target system I get the error:

can't open '/dev/misc/rtc'

Is there a buildroot option or setting I've not noticed to enable hwclock?

Hi,

Please verify the output of the kernel during bootup. Also accessible 
via "dmesg" after login. Make sure to have some sort of message, which 
confirms to activate a real time clock. Setting up a real time clock 
module is an issue of the kernel. Not buildroot itself.
 >dmesg|grep -i clock
or
 >dmesg|grep -i rtc

Regards,
Marcus

When  I use dmesg|grep -i rtc, I get the response:
platform rtc-cmos: registered platform RTC device (no PNP device found)

When I use dmesg|grep -i clock, I get the response:
Switching to clocksource pit

If this is dealt with by the kernel, do I have to look through the linux26
menuconfig instead?
