dont get kernel booted, boot process ends with 'Starting kernel ...'

juergenvorbach · ‎11-14-2014

I have done the installation part on a SD-Card as described and shown below. But I just get until a Starting Kernel ... message, no further.

Does anyone know how to fix this?

Thanks in advance

For those who run into the same problem.

I changed my setup script to:

#!/bin/sh

DEV=sdc

BOOTLOADER=u-boot-imx6qsabresd_sd.imx

KERNEL=uImage_imx_v7_defconfig

DTB=uImage-imx6q-sabresd-ldo.dtb

#

#Copying the Boot Loader Image, offset=1k

sudo dd if=$BOOTLOADER of=/dev/$DEV bs=512 seek=2 conv=fsync

#Copying the Kernel Image and DTB File, offset=1M

sudo dd if=$KERNEL of=/dev/$DEV bs=512 seek=2048 conv=fsync

#DTB, offset=10M

sudo dd if=$DTB of=/dev/$DEV bs=512 seek=20480 conv=fsync

and now it runs.

Hello,

Good work Juergen Vorbach,

works fine... :smileyhappy: .... DTB=uImage-imx6q-sabresd-ldo.dtb

interesting to know.

Thanks and Regards.

Best Luck.

jaymind · ‎11-18-2014

Hi juergenvorbach,

Can you please write down your all arguments which shown at 'printenv' command in u-boot

and also mention your details that which type of board you used, about RFS and Kernel uImage,

so its good to answer in best way.

I think there may be problem in u-boot side as I assume.

Thanks

jaymind · ‎11-18-2014

Hello,

Some errors as shown in your argument.

We will correct it, maybe its work.

in setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk0p2 rootwait rw video=mxcfb1:dev=ldb,LDB-XGA,if=RGB666

there are /dev/mmcblk0p2 instead of /dev/mmcblk0p1 (name of SD card partition where uImage) and video=mxcfb1 insted of mxcfb0

set below argument in your u-boot from starting.

setenv console ttymxc1

setenv baudrate 115200

setenv mmcdev 0

setenv mmcpart 1

setenv mmcroot /dev/mmcblk0p1 rootwait rw

setenv mmcargs setenv bootargs console=${console},${baudrate} consoleblank=0 root=${mmcroot} xl4 video=mxcfb0:dev=ldb,LDB-XGA,if=RGB666

check with xl4 and without xl4 in last argument. (don't forget)

after entering all arguments and save it if you get u-boot prompts then you are on correct direction.

and enter " bootm " in u-boot prompts after setting all arguments to extract kernel.

Also provide me some hyper-terminal / minicom output after save all above argument and also your 'printenv' output of u-boot then will get idea and move forward to correct direction.

Hope above information helpful to you.

Best Luck

jaymind · ‎11-19-2014

Hello Juergen,

Thanks for providing logs,

Can you please provide me the all arguments of u-boot? so it's easy to go forward.

printenv

I think so it will work, but after doing some correction.

some more arguments would be set,

setenv script boot.scr

setenv loadbootscript fatload mmc ${mmcdev}:${mmcpart} ${loadaddr} ${script};

setenv bootcmd mmc dev ${mmcdev};mmc dev ${mmcdev}; if mmc rescan; then if run loadbootscript; then run bootscript; else if run loaduimage; then run mmcboot; else run netboot; fi; fi; else run netboot; fi

setenv uimage boot/uImage

NOTE : important thing here to notice is that for setting uimage arguments give the correct path where your uImage lies on SD card. (i.e. here it is in boot directory - do not include ' / 'before directory)

so revert me back will u-boot environment and also result output after doing above changes.

Suggestion : If you don't want to save all these env in u-boot then just sets it to in u-boot and print to verify all, they set for the current console/season and automatically set default at next time start.(so its easy for testing purpose)

Thanks and Regards

I dont have anything running on 172.30.50.225, no tftp server or anything else.

jaymind · ‎11-19-2014

Hello,

Actually as per your old logs its shown that your loadaddr is loadaddr=0x12000000.

also be sure that your uimage lies at boot/uImage path. Is this correct ??

so also set it to loadaddr=0x80800000, it may be one of reason.

setenv loadaddr 0x80800000

also set some more below arguments.

However its set already or not just set it one more time.

setenv fdt_high 0xffffffff

setenv initrd_high 0xffffffff

setenv loadbootscript fatload mmc ${mmcdev}:${mmcpart} ${loadaddr} ${script};

setenv loaduimage ext2load mmc ${mmcdev}:${mmcpart} ${loadaddr} ${uimage}

setenv bootscript echo Running bootscript from mmc ...; source

I am not sure about FTP boot, it because of that it can't get loaduimage or loadbootscript or bootscript or mmcboot that's why it go to run netboot.

also set below argument at last.

mmcboot=echo Booting from mmc ...; run mmcargs; bootm

and please provide me u-boot environments all. (by use of 'printenv') after setting all above arguments.

Best luck

Hi Juergen

you can check below as possible reason

https://bugzilla.yoctoproject.org/show_bug.cgi?id=6703

Best regards

Hi Igor,

thanks for your response.

The solution provided doesnt change anything in my case.

Disconnecting the hdmi cable or changing some values as described - still the same boot procedure 'till 'Starting kernel ..."

I keep trying, maybe I overread something.

thanx, kind regards

Hi Juergen,

are you sure that kernel stops booting or are there no more activity on the console?

May be that's the problem? how to set bootconsole on imx6 board

Hi Stefan,

thanx for your response.

that is all I can see at the console when it stops at 'Starting kernel

...', so I think it never really starts to boot.

When I plug in my TFT via HDMI it runs into power save mode or if it

stays connected and I reset it stays in power save mode, just the same

behavior.

But when I boot the android kernel (r13.4) that is provided by freescale

- it runs, but I would like to use the yocto kernel.

kind regards

Juergen
