Hi Robert, THANK YOU SO MUCH FOR THAT HINT! :) The new kernel version and the hint from Acmesystems mailing list to explicitely set the XTALs clock frequencies in the dts file are the solutions for both problems -- the running clock and not being able to poweroff the board! Now the clock is just *in* time and poweroff powers off the board. GREAT! I am happy! Thank you VERY much!

[beagleboard] [OT]: ATMEL AT91SAM9G25/ARM926EJ-S Helpneededforinterpretationofadmesgmessage
Hi, I am using a Arietta G25 (http://www.acmesystems.it/arietta) with Robert Nelsons Kernel 3.17.3 and the kernel configuration provided by Acmesystems for their Debian Linux for the Arietta G25 based on Linux kernel 3.16.1. As far as I know the only patches they used are agains dts/dtb files (I use the same ones) and to configure the kernel without the need of using makeconfig. So far so nice...the system boots with a Gentoo stage3 rootfs. There only two things left: 1.) shuthdown -h -H now (as said to be used by Acmesystems) reboots the system instead of powering it off (which works with their image). 2.) The at91 RTC is missing the Real...the difference are several minutes per hour. I compared the dmesg output of the Arietta G25 booted with one and the other system. With the Gentoo system there is one line which irritates me and may indicate a way to a solution for the RTC problem: [0.00] Main crystal frequency not set, using approximate value [0.00] master clk is overclocked [0.00] sched_clock: 32 bits at 128 Hz, resolution 7812500ns, wraps every 167772160ns [0.00] Console: colour dummy device 80x30 [0.054687] Calibrating delay loop... 220.07 BogoMIPS (lpj=862208) The clock frequency of the CPU is unknown??? The Debian system does not have that problem... Any suggestion how to fix one or (better! :) both problem is VERY 8) appreciated! Thank you very much in advance for any help!

About the time clock , as I know , its about the crystal , called jitter ?

Hi liyaoshi, thanks for your posting! I am not searching for workaround -- the small Arietta will become a mobile device which has no connection to the internet. I am searching for the reasons of the two problems and want to fix the (currently unknown) bugs behind that. Even without sync an RTC should not become THAT wrong as the RTC of the Arietta currently.

Re: [beagleboard] [OT]: ATMEL AT91SAM9G25/ARM926EJ-S Helpneededforinterpretationofadmesgmessage
Hi liyaoshi, in the meanwhile I digged deeper into the kernel and found, that in Linux 3.17.3 there is a new configuration item AT91_USE_OLD_CLK which is set to n which in turn set USE_OLD_CLK to n. But last get set when using Linux 3.16.1. I compiled Linux 3.16.1 with the instructions of Acmesystems (including the patch, which inserts some dts files and the kernel configuration itsself) and it seems (no long period done though) that the RTC problem is gone. As Robert mentioned in his mail to this thread, there were a lot of RTC changes AND (TADA!) the Arietta should be supported by the mainline kernel, which in turn makes me completly independant from any patches by acmesystems (*NO* inplicite or explicite cirtism intended here!!!), which are GOOD news. Gentlemen...start your compilers!
