Kernel 4.x build?

[Chris]

I built many 3.x kernels for olinuxino, but have no success with 4.x.
I followed these instructions:
https://github.com/koliqi/imx23-olinuxino
and took this rootfs:
https://www.olimex.com/wiki/images/4/49/Imx233_kernel_2.6_ARCH_FS_WIFI_release_4.torrent
but olinuxino fails booting:

Did anybody already successfully build a 4.x kernel and could provide a working .config?

[JohnS]

Did you rebuild every binary, including of course systemd?

I don't see how you can use that rootfs as-is...

John

[Chris]

Did you rebuild every binary, including of course systemd?

No, because the used rootfs is officially provided by olimex especially for olinuxino and Arch Linux release 4:
https://www.olimex.com/wiki/IMX233#Kernels
So I can could expect to work with kernel 4, or?

[progmetalbg]

Your kernel command line is wrong:

[0.000000] Kernel command line: console=ttyAMA0,115200 root=/dev/mmcblk0 init=/usr/lib/systemd/systemd rw rootwait

The Olimex arch linux image is using the old init, not systemd

[Chris]

Thanks for the hint - works perfectly now!
