My application requires me to log the time when an event happens. The PXA270
on verdex pro has a RTC, which resets on power cycles. So I thought of
attaching an external battery backed intersil 1208 RTC. I would be glad if
someone could point me to how to get this to work. My requirements are
1) Program the current time in 1208. Hopefully this will be one time setup
2) When the event happens, either read the 1208 directly, or set the
internal RTC with current time on bootup and use the system time thereafter.
I understand I will have to set the internal RTC on every boot.
I know 1208 works on I2C. I haven't worked on I2C before, so any help to get
me started would be appreciated.
Just to let you know, I was trying to compile 1208 support as a kernel
module, but it would always default to kernel-module-rtc-sa1100, which is
the module to access PXA's RTC. So I assume I cannot directly use the
external RTC. I will have to program the internal RTC using the external
