Re: [Crash-utility] using crash for ARM
Hi,
I got the crash up on the target but I get following error.
WARNING: kernels compiled by different gcc versions:
./vmlinux: (unknown)
live system kernel: 4.4.3
crash: cannot open secondary temporary file
I have taken System.map and vmlinux from the same build path.
Regards,
Oza.

Hi,
I would like to use crash utility on ARM.
what I understand is there might be two ways to go about it.
1) cross compile whole crash for arm itself, which doesnt seem to be
good option because on arm target we will need lots of depedent
packages.
2) run crash on x86 and have gdbserver/remoter server compiled on
target. and have serial connection and so on..
please suggest instructions or any pointers regarding the same.
Regards,
Oza.
If you are talking about running crash on a live ARM system, then
option #1 is the only possibility. Option #2 does not exist for
the crash utility; live system access requires either /dev/mem,
/proc/kcore, or the /dev/crash misc driver.
