i.Mx6q kernel stuck

[faustosessego1]

Hi,

I am trying to port the kernel 4.1-1.0. from sabresd to my custom board.

Everything builds without an error and I get a new zImage, as shown below.  However,  the Kernel hangs while starting up.

My define called into custom_board.h (u-boot) are

"if run loadimage; then " \
"run mmcboot; " \

"else run mmcbooterror; fi; " \

I compile the kernel by

#!/bin/bash
export ARCH=arm
export CROSS_COMPILE=arm-linux-
export PATH=/home/fsessego/Documents/Yocto/fsl-linaro-toolchain/bin/:$PATH
cd ../linux-fslc
make clean
make imx_v7_defconfig
make -j4 zImage imx6q-custom.dtb

I suspect something wrong with my zImage when I specify the load address.

Hi Fausto,

If you are using a custom board then u-boot has no support for your board. You may refer to the porting guide that Igor pointed you here: https://community.nxp.com/thread/448757

Hi Carlos,

finally i'm able to boot my custom board.

Now i have another problem.

I load correctly u-boot, kernel and root-fs but the board stucks:

-->Stuck

Sometimes i'm able to write the user "root" but, after few seconds i logged, the system stuck.

Can you help me?

Can it depend on Kernel?

Thanks

Hello Fausto,

That's a long time ago since your message on this thread, there was no answer, but I have the same issue with another board with an iMX6 too. I'm usually able to login, but after few seconds or minutes the system is stucked (or at least the console !) Have you got solved this ?

Thanks,

Joel

Hi Fausto,

actually the kernel will not need modifications because you may use the same machine in your custom board. so, rather than the kernel you may edit the Device Tree and the bootloader to match your custom board.

The following thread shows how to modify a bootloader for a custom board which in this case is the Udoo Quad board

U-Boot Migration Example 

Next you can find a doc showing how to implement a device tree for a custom board which again is the Udoo Quad

Basic Device Tree for the Udoo Board 

Finally you can find here the hole process to build an image based in NXP kernel with a custom  bootloader and a custom device tree.

Building Linux Image with QT5 for UDOO Quad 

Please note that specific matters about custom boards are beyond free support scope. For further help you may be intersted in our Professional Support and Service Resources|NXP 

Best regards,
TIC

Hi Carlos,

i didn't modify the kernel but i created only the .dts file for my custom board.

The imx6q-custom.dts is:

/dts-v1/;

#include "imx6q.dtsi"
#include "imx6q-custom.dtsi"

/ {
model = "i.MX6 Quad CUSTOMBoard";
compatible = "fsl,imx6q-custom", "fsl,imx6q";
};

The mx6q-custom.dtsi is:

#include <dt-bindings/gpio/gpio.h>
#include <dt-bindings/input/input.h>

/ {
memory{
reg = <0x10000000 0x40000000>;
};
};

&uart1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_uart1>;
status = "okay";
};

&usdhc4 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_usdhc4>;
non-removable;
status = "okay";
};

&iomuxc {
imx6q-sibiri {
pinctrl_uart1: uart1grp {
fsl,pins = <
MX6QDL_PAD_SD3_DAT7__UART1_TX_DATA 0x1b0b1
MX6QDL_PAD_SD3_DAT6__UART1_RX_DATA 0x1b0b1
>;
};

pinctrl_usdhc4: usdhc4grp {
fsl,pins = <
MX6QDL_PAD_SD4_CMD__SD4_CMD 0x17059
MX6QDL_PAD_SD4_CLK__SD4_CLK 0x10059
MX6QDL_PAD_SD4_DAT0__SD4_DATA0 0x17059
MX6QDL_PAD_SD4_DAT1__SD4_DATA1 0x17059
MX6QDL_PAD_SD4_DAT2__SD4_DATA2 0x17059
MX6QDL_PAD_SD4_DAT3__SD4_DATA3 0x17059
>;
};
};
};

I set only the uart and the micro SD interface.

Here you are my interface

Where is the problem from your point of view?

Can it depend on wrong ram configuration? 

Let me know

Thanks

What u-boot are you using?

I think the problem is there. When I was writing Building Linux Image with QT5 for UDOO Quad  I had the same issue, booting sequence hanged, and the problem was that the bootloader was not adapted for UdooQuad board.

I'm using u-boot 2016.07 and kernel 4.1-1.0.x.

I get u-boot and kernel directly from yocto, so i think the matching is right.
