Arndale : Does boot u-boot but fails with a "Wrong Image Format" which
should be fixed by SR #248024 (already accepted by Alex, thanks). I
fixed it manually before the SR were accepted but I get lots of
"cpufreq: __target_index: Failed to change cpu frequency: -22" errors
logged but I finaly get a prompt.
Yes, you can work around this by echo'ing "performance" into the
governor sysfs file. I haven't quite figured out what's going wrong here.
Ok. It seems that the CPU voltage cannot be adjusted ("exynos-cpufreq
exynos-cpufreq: failed to set cpu voltage to 1100000").
Maybe we are missing a power chip driver in the kernel?
Maybe - I have no idea about power chip drivers :). Can you take a look?
The power chip driver is included. So maybe just a broken cpu freq for exynos?
Serial console and USB2 work, but eth0
seems to have some problems. Second boot seems to be broken (I fallback
to a dracut prompt).
I though I had fixed that one. The problem is that dracut doesn't
include all modules required to access the SD card. So I added them to
INITRD_MODULES in /etc/sysconfig/kernel in config.sh.
Can you please check on first boot whether the line was properly updated?
There is no /etc/sysconfig/kernel file on firstboot.
O_o. There should be.
Using dracut prompt, I listed
"/lib/modules/3.16.1-2.g2ab6585-lpae/kernel/drivers/mmc/host" folder and only
got:
mmci.ko omap.ko omap_hsmmc.ko sdhci-pltfm.ko sdhci-tegra.ko sdhci.ko
So, no dw_* mmc modules. But how those mmc modules get added?
According to dracut documentation:
https://www.kernel.org/pub/linux/utils/boot/dracut/dracut.html#_adding_kernel_modules
We should use /etc/dracut.conf or /etc/dracut.conf.d/myconf.conf and NOT
/etc/sysconfig/kernel
Am I wrong?
First boot is ok since kiwi adds dw_* mmc modules in initial initrd. But 2nd
boot is broken because generated initrd does not include them.
