Part Number: AM3352
Tool/software: Linux
Hello.
I have a problem in RTC. The static date/time (2018/03/26 15:36:31) can be read by date command. Attatched file teraterm.log is dmesg command dump.
In the file, I found a dump the string beginning "@@@@@", which is RTC register data(date/time) when omap_rtc is probed.
What I want to do is to keep increacing times of day even if power switch is turned off.
In software side, please give me some advice.
What I want to know is:
1. Which config should I set in building kernel?
2. Are there any modifications for omap_rtc driver? If yes, how should I modify?
3. In boot sequence, how can I call hctosys after probing omap_rtc?
4. Further advice?
My environment is: using Cutom board like AM335x EVM, and ti-processor-sdk-linux-rt-am335x-evm-04.03.00.05.
Best regards.
