Hi Kevin,
Yes, I did. No difference. When I try to load the rtc-cmos driver it
says:
:codes# modprobe rtc-cmos
FATAL: Error inserting rtc_cmos
(/lib/modules/2.6.23-rc1ide_2/kernel/drivers/rtc/rtc-cmos.ko): No such
device
I also just tried compiling the test program at the end of rtc.txt in
the kernel tree. The first thing it tries to do is open /dev/rtc0 and
fails, even though I've created it with mknod /dev/rtc0 c 10 135 (and
re-loaded the rtc modules). This seems to be the crux of the problem:
that node cannot be opened.
What I don't understand yet is what happens when the rtc-m48t86 driver
is loaded. Dmesg says that the chip is registered "as rtc0" but what
does that mean? It says that whether or not I've created the /dev/rtc0
-> /dev/rtc link, so it doesn't seem to look at what's in the dev
tree. Could this be a udev problem of some kind? Is there some place in
the udev setup where I need to configure something that is missing?
