Anyone got Linux 3.1 or Linux 3.0 running on EVK

netstv — Fri, 02 Sep 2011 22:21:55 GMT

We have been trying for a day or so now to get the NFS booting of the Linux 3.x kernel. There is a setting in there for the iMX28EVK but all we get is a hang once the kernel is starting up.

We have double checked the MACH_ID and that doesn't seem to be the problem.

So I'm just curious if anyone has this working.

Thanks.

Can you post your boot log?

Hello Fabio,

I work with Steve. There is really nothing in the boot log. U-boot runs fine and loads the kernel, decompresses it and displays message "Starting kernel" and we don't see any console output.

However when using 2.6.35 kernel and associated freescale patches, using the same u-boot and kernel command line parameters board boots just fine.

We have noticed that there have been lot changes between 2.6.35 and the latest 3.1.0 RC available from ARM git and also 3.0 git source from pentronix git.

Particularly stuff in arch/arm/mx28, mx23 seems to have been consolidated into arch/arm/mach-mxs

make sure that you have

CONFIG_SERIAL_AMBA_PL011=y
CONFIG_SERIAL_AMBA_PL011_CONSOLE=y

in Linux kernel config and your kernel command line looks like

console=ttyAMA0,115200 root=/dev/mmcblk0p3 rw rootwait

you have to modify linux_prep bootlet to do so
