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:
[ 0.000000] Main crystal frequency not set, using approximate value
[ 0.000000] master clk is overclocked
[ 0.000000] sched_clock: 32 bits at 128 Hz, resolution 7812500ns, wraps
every 16777216000000000ns
[ 0.000000] 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!
Best regards,
Meino
