Hi,
based on your suggestions from thread "[Xenomai] ipipe-core-3.10 patch
for arm"
I started testing Xenomai on an i.MX6 board [1].
* checked out branch imx_3.10.17_1.0.0_ga from linux-2.6-imx.git [2]
* merged vanilla v3.10.32 tag
resolved 3 conflicts:
drivers/net/can/flexcan.c
drivers/usb/host/ehci.h
sound/soc/codecs/wm8962.c
* applied ipipe-v3.10.32.patch
resolved 4 conflicts:
arch/arm/mach-imx/clk-imx6q.c
arch/arm/mach-imx/mach-imx6q.c
arch/arm/mach-imx/mm-imx27.c
arch/arm/mach-imx/mm-imx3.c
* applied xenomai-2.6 support (prepare-kernel.sh)
My box boots without errors and seems to be quiet stable at the first
glance.
Linux arm 3.10.32-xenomai-armv7-x1 #24 SMP Sun May 4 12:17:10 CEST 2014
armv7l GNU/Linux
The first thing I observed is a system time problem:
the RTC and system time clocks get out of phase very quickly.
I do compare the timers (end - start) on console by calling:
- hwclock && date (start)
- wait an hour or more
- hwclock && date (end)
The hwclock time is always o.k. but the system time reported by date is
roughly 25% faster.
Do you have an idea what could go wrong here?
Many thanks for your great job and best regards
Ralf
