First check you have a RTC. on the 7500 it is optional. From: osogoet <> To: Sent: Wednesday, August 24, 2011 1:23 PM Subject: [ts-7000] TS-7800, Cannot access the Hardware Clock via any known method. I have been running kernel 2.6.34 from microSD on TS-7800, and everything goes well.
However, recently I encounter the problem of RTC. While, it's OK for TS-7800 board with 'BOOTROM - built Jun 10 2009', the RTC of TS-7800 board with 'BOOTROM - built May 11 2011' is not recognized. The related boot message is: Setting the system clock. Cannot access the Hardware Clock via any known method. Use the --debug option to see the details of our search for an access method. Unable to set System Clock to: Thu Jan 1 00:00:12 UTC 1970 (warning). and the results of 'hwclock' and 'hwclock --debug' are: ts7800:~# hwclock Cannot access the Hardware Clock via any known method. Use the --debug option to see the details of our search for an access method. ts7800:~# hwclock --debug hwclock from util-linux-ng 2.13.1.1 hwclock: Open of /dev/rtc failed, errno=2: No such file or directory. No usable clock interface found. Cannot access the Hardware Clock via any known method. Also, there are /dev/rtc and /dev/rtc0 on TS-7800 board with 'BOOTROM - built Jun 10 2009', there is neither /dev/rtc nor /dev/rtc0 on TS-7800 board with 'BOOTROM - built May 11 2011'. How could it be fixed? __._,_.___
