Re: [Crash-utility] using crash for ARM
----- Original Message -----
Hi,
I got the crash up on the target but I get following error.
Well, that's impressive...
WARNING: kernels compiled by different gcc versions:
./vmlinux: (unknown)
live system kernel: 4.4.3
That's a harmless warning, but what do these commands show:
$ strings vmlinux | grep "Linux version"
and
$ cat /proc/version
The gcc-related data in those two strings are being compared.
crash: cannot open secondary temporary file
When do you see that message?
I have taken System.map and vmlinux from the same build path.
The System.map file is not necessary if the vmlinux is the kernel
that the live system is running.

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.
