kernel panic not syncing: Attempted to kill the idle task! Rebooting in 180 seconds.

[nareshpuli]

Hi,

we are using P2020 Processor, when i power up the board 

NOR BOOT CONSOLE:  U_boot is working  fine, but at kernel level it stalls middle only it shows like kernel panic not syncing: Attempted to kill the idle task! Rebooting in 180 seconds. or  Unable to handle kernel paging request for data at address 0x00000009 Faulting instruction address: 0xc0093780  it doesn't boot totally what could be the problem, even it shows same thing from the SD boot also, i am attached console log , please help me.

Hello naresh puli,

Are you using NXP demo board or bringing up a new target board now?

According to the log, it seems that you built images by yourself, would you please provide your Kernel configuration and dts file?

In addition, what had you modified in u-boot?

Thanks,

Yiping

hi,

how can i fix this kernel panic issue, how can i come out this problem  its stopping me for a long time?? please help me

linux-headers-3.19.0-71-generic

# see Documentation/kbuild/kconfig-language.txt.

#

mainmenu "Linux/$ARCH $KERNELVERSION Kernel Configuration"

config SRCARCH

string

option env="SRCARCH"

source "arch/$SRCARCH/Kconfig"

pls give me specific response

Thanks

regards

naresh

[yipingwang]

Hello naresh puli,

Please provide Kernel configuration file (.config) and dts file, then I could do verification on my target board.

Thanks,

Yiping

[nareshpuli]

hi yiping,

we are bring up new boards, how we check the kernel configuration and dts file

regards

naresh

have a nice day...

[yipingwang]

Hello naresh puli,

According to your Kernel boot log, Kernel uImage was generated on 2016-10-26. If it was generated by you, please send the .config file to me to do more investigation, which was saved with the command "make ARCH=powerpc menuconfig".

If the Kernel image was not generated by you, please boot your target board with the attached images, and captured the log to me.

tftp 1000000 uImage
tftp c00000 dtb
bootm 1000000 - c00000

If you don't have tftp sever, you also could use CodeWarrior to program uImage and dtb file to NOR flash, then boot from NOR FLASH directly.

Thanks,

Yiping
