Crash log and Kernel dump for ARM architecture with imx6 processor

[pradeepanbumani]

Hi,

I am using device with imx6 processor with

1) linux kernel: 3.18.29

2) openWRT Chaos Calmer.

The issue is, during a kernel panic or crash, no crash logs or the kernel core dump is created. Is there any way to get the logs or the kernel core dump?

In the kernel configuration file, the crash log (CRASHLOG) support is provided only for architectures other than ARM, SPARC, PPC. Is there anyway that we can generate these crash logs for ARM architecture. The dependency to generate crash logs are as below

Symbol: CRASHLOG [=n] 

Type : boolean

Prompt: Crash logging

Location:

(1) -> General setup

Defined at init/Kconfig:1282

Depends on: (!NO_BOOTMEM [=y] || HAVE_MEMBLOCK [=y]) && !ARM [=y] && !SPARC && !PPC

Thanks

Hi Pradeep

it is not supported in official linux releases and one can post on OpenWrt wiki:
