I use revision 59ca38f of branch 4.2. In my kernel config i activated CONFIG_FEC.

When trying to set the ip address, i get an error.

Hi,
Did you crosscompile kernel, if yes, which toolset? which version of udoo you have, quad or dual?

Hardware: Udoo quad
Compiled within yocto 1.8, using gcc 4.9.2.

The devicetree is used as is, with the addition of one spi port and two spidev devices.

The kernel bootup messages (the spidev warning messages and stack traces are only warnings...):

Btw: With your kernel 4.0.8 it worked.

I (CC) compiled 4.2 and via DHCP works normally. I'll check manually later.

I couldnt reproduce this problem. Could you remove your changes related to spi and test it again? I have some idea.

btw. could you move " MX6QDL_PAD_EIM_EB3__GPIO2_IO31 0x80000000 /* ethernet power */" from enetgrp to hoggrp and test again?

Even without the spidev patch, i get the same error.

I moved the line starting with "MX6QDL_PAD_EIM_EB3__GPIO2_IO31" from enetgrp to the end of hoggrp -> no change, the error is still present.

could you supply your config file via some pastebin page or could you test configfile: http://kowalczyk.ws/imx/kernel/config-4.2

I couldn't reproduce this problem with my config file and spi driver only for imx. Probably you compiled in some other driver which generate problem.

Thank you for your test. I use the following kernel config:

I will try to test the mainline kernel tomorrow

Hi,

We couldnt configure spidev directly in a dtsi file. You have to configure them via /sys or /proc

related to spi DT problem please check:

 spidev0: spi@0 {
                compatible = "rohm,dh2228fv";
                reg = <0>;
                spi-max-frequency = <54000000>;
        };
        spidev1: spi@1 {
                compatible = "rohm,dh2228fv";
                reg = <1>;
                spi-max-frequency = <54000000>;
        };

and then test SPI again and later ethernet.

The mainline kernel 4.2 with my configuration produces the same error as mentioned in my first post.
The mainline kernel 4.2 with your configuration http://kowalczyk.ws/imx/kernel/config-4.2 does not boot, see https://paste.fedoraproject.org/269610/ for a log.

For now i will continue to use 4.0.8. When i have some spare time i will try to find the reason for my crash.

Hi, Your log file for booted kernel looks like a log for vanilla kernel. Unfortunately we couldn't boot udoo with vanilla kernel because of bug in usb driver. Please compile a last udoo 4.2 branch with my config file and then make a test.

The configuration from http://kowalczyk.ws/imx/kernel/config-4.2 works within yocto and with your kernel 4.2. So it is an issue with my configuration...

Could you test your config with last changes from 4.2 branch and new config file from that same location? I updated config http://kowalczyk.ws/imx/kernel/config-4.2.

So i found the problem in my configuration:

CONFIG_MICREL_PHY=y

When removing this, it works.
I will test your SPIdev configuration next.

Spidev work with the current version of the 4.2 branch.
