hwclock doesn't work
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

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?
